DESCRIPTION JP2010232840
The present invention provides an acoustic control console that allows a user to adjust the color
combination of LED operators. A sound adjustment console includes a color matching adjustment
mode selection button 16 and adjustment target designation buttons 17, 18, 19 and 20. The user
operates the color matching adjustment mode selection button 16 to set the color matching
adjustment mode, and operates the adjustment target designation button 17, 18 or 19 to
designate one of the RGB LEDs as the adjustment target. When the user operates any of the
operators (for example, channel selection button 8 etc.), the brightness of the LED corresponding
to the color designated as the adjustment target in the multicolor LED unit 10 corresponding to
the operator is relatively The ratio of the brightness of the plurality of LEDs is changed so as to
be high, and the coloration of the color is enhanced. This work is performed for each LED and
each LED button 9. [Selected figure] Figure 3
An acoustic control console capable of adjusting the coloration of the LED operator and an
operation method for adjusting the coloration of the LED operator.
[0001]
The present invention is an acoustic control console having a plurality of operators used for
operations etc. for mixing acoustic signals of a plurality of channels, and among the plurality of
operators, an LED for each predetermined color of a plurality of colors. The present invention
relates to an LED controller including a multicolor LED unit as one set.
[0002]
One set of multicolor LED units using three LEDs (Light Emitting Diodes) corresponding to RGB
(red (R), green (G) and blue (B)) which are three primary colors of color It is known that various
10-04-2019

colors are expressed by configuring and emitting each color of the red LED, the green LED, and
the blue LED at an arbitrary ratio.
[0003]
The multicolor LED unit as described above is used in various parts of various devices.
In one of the usage examples of the multicolor LED unit, a multicolor LED unit may be
incorporated in an operator provided in an electronic device to constitute a so-called selfilluminating operator (LED operator).
For example, it has been conventional practice to incorporate a multi-color LED unit for a number
of controls provided on an audio control console for audio mixing. In this case, it is possible to
intuitively grasp the on / off state of the parameter assigned to the LED operator, the type of the
parameter, and the like through lighting of the multicolor LED unit and color coding of the light
emission color. Generally, the user of the sound control console has to perform complicated work
using a large number of operators, so the light emission of the multicolor LED unit allows
visualizing parameter on / off status, parameter type, etc. Intuitive grasping is advantageous in
terms of operability and operability.
[0004]
By the way, each LED which comprises a multi-color LED unit has the fault that the dispersion |
variation in the luminescent property for every solid is large. For this reason, even if the same
drive signal is given to each LED of a plurality of multicolor LED units to emit light with the same
light emission characteristic, the mutual brightness of each multicolor LED unit and the emission
color Unevenness in color may occur. For example, even if it was tried to make a plurality of
multicolor LED units emit light with the same red color, it was not always the case that all the
multicolor LED units emit light with the same brightness or color "red".
[0005]
In order to solve the problem of variations in the light emission characteristics of individual
10-04-2019

LEDs, devices have conventionally been devised to adjust the luminance and color tone of each
individual LED. As an example, there is a technology that automatically measures the lighting
condition of each LED, compares the result of the automatic measurement with the drive signal
for lighting the LED, and corrects the light emission characteristic of each LED based on the
comparison result. (See, for example, the following Patent Document 1 and the following Patent
Document 2).
[0006]
Also, in the past, there has been an acoustic control console having a configuration for changing
the light emission color of a self-illumination type operating element incorporating a multicolor
LED unit or the like. According to this, the user brings up a screen for performing setting relating
to the operating element on the display provided on the sound adjustment console, and selects a
desired color from among a plurality of predetermined options on the screen. Thus, the luminous
color can be selected for each operator (see Non-Patent Document 1). Further, in a controller for
performing a voice editing operation and a video editing operation using a computer, the key top
portion of the operating element provided on the operation panel is illuminated from the inside
by a color LCD screen built in the operation panel. Thus, there has been a technology that can
freely change the display color, display character, etc. of each operator according to the display
content of the screen (see Non-Patent Document 2).

[0009]
However, since the sound adjustment console described in Non-Patent Document 1 is configured
to select the light emission color of the self-illumination type operator from among a plurality of
10-04-2019

color choices in advance, the user creates a light emission color of an arbitrary color
combination. There was no one who could adjust the color.
Further, the technique described in Non-Patent Document 2 aims to change the display color and
display character of each operation according to the function to be controlled by the controller,
and the light emission color of each operation It does not disclose creating or adjusting the color.
And, since this technology is a technology to change the display color etc. of the operation
element by displaying the display thing corresponding to the operation element image on the
LCD screen, the self-illumination type of the sound control console having no such structure It
can not be applied to creating an emission color of an arbitrary color in an operator.
[0010]
In short, in the conventional sound control console, the color combination of the light emission
color of the LED operator incorporating the multicolor LED unit is arbitrarily generated by the
user operation, or the color combination of the emission color of the LED operator is adjusted by
the user operation I could not do it.
[0011]
Also, even if it becomes possible for the user to work to adjust the coloration of the multicolor
LED unit (LED operator) in the sound control console, the work is incidental from the original
function of the sound control console It is.
In addition, the task of the original function of the sound control console is a highly specialized
and very complex task. From these points, in order to be able to adjust the coloration of the
multicolor LED unit by the operation of the user, it is desirable to be able to perform the
coloration adjustment of the multicolor LED unit by a method as simple and easy to understand
as possible.

color of an LED operation member incorporating a multicolor LED unit can be arbitrarily created

incorporated in the LED operator corresponding to the manipulated operator is relatively high In
order to achieve the above, it is characterized by comprising color adjustment means for
changing the ratio of the brightness of the plurality of LEDs.
[0014]
According to the sound adjustment console of the present invention, in the color adjustment
mode, the user designates at least one of predetermined plural colors constituting the multicolor
LED unit as the color to be adjusted, and the plural operators. The brightness of the LED
corresponding to the color designated by the adjustment target designation means in the
multicolor LED unit incorporated in the LED operator corresponding to the operated operator by
operating any one of The ratio of the brightness of the plurality of LEDs can be changed such
that is relatively high.
As a result, the user can create a color combination of a desired light emission color or adjust the
color combination for each of the LED operators by the user's own operation.

[0041]
The display control circuit 24 individually controls lighting of each of the LEDs constituting each
multicolor LED unit 10 (LED button 9) according to a lighting control method known as dynamic
lighting, which is conventionally known, based on an instruction given from the CPU 21. FIGS. 5A
and 5B are diagrams for explaining the lighting operation of the multicolor LED unit 10 (LED
button 9) according to the dynamic lighting method, and the horizontal axis represents time. In
(a), a predetermined number (eight in the example of the drawing) of multi-color LED units 10
are sequentially lit every predetermined lighting cycle (in the example of the drawing, 12
milliseconds (12 ms)) by the dynamic lighting method. It shows how to make
[0042]
In the example shown in FIG. 5A, the lighting control of the eight multicolor LED units 10 is
sequentially performed one by one with the lighting cycle of 12 ms, so the time allocated to one
multicolor LED unit 10 is 12/8 ms. = 1.5 ms. The display control circuit 24 controls lighting of
the eight multicolor LED units 10 one by one in the lighting cycle of 12 ms while switching the
multicolor LED units 10 to be lighted control one by one every 1.5 ms. Do. Therefore, focusing on
one multi-color LED unit 10, one multi-color LED unit 10 lights on the basis of lighting control
10-04-2019
13
only for a period of 1.5 ms every cycle of 12 ms, and is turned off for other periods. It means that
the blinking operation is repeated.
[0043]
Although each multi-color LED unit 10 is repeatedly blinking at a lighting cycle (about 83 Hz)
every 12 ms, it seems that each multi-color LED unit 10 is always on due to the afterimage effect
to human eyes It looks like Therefore, although the multi-color LED unit 10 actually blinks at the
timing shown in FIG. 5A, it looks like it is always on to the human eye due to the afterimage
effect.
[0044]
FIG. 5B is a view for explaining the operation of lighting control of one multi-color LED unit 10 in
a period of 1.5 ms. The display control circuit 24 controls each of the LEDs 11, 12, and 13 based
on lighting control data for each of the three red LEDs 11, the green LEDs 12, and the blue LEDs
13 that constitute the multicolor LED unit 10 in a 1.5 ms period. Lighting control of 13
individually.
[0045]
The lighting control data for each of the LEDs 11 to 13 is, as an example, data for controlling the
timing of turning on and off the LEDs within a period of 1.5 ms. The CPU 21 gives an instruction
based on the lighting control data to the display control circuit 24, whereby the display control
circuit 24 controls the lighting time of each LED in the 1.5 ms period. In this embodiment, the
lighting control data is constituted by a 6-bit binary code, and the value of “1” or “0” set for
each bit turns on / off the LED corresponding to the lighting control data. Control the timing.
That is, the LED turns on at the on timing of each bit of the lighting control data, and the LED
turns off at the off timing. When lighting control data is configured by a 6-bit binary code, 64
types of on / off timing patterns can be expressed by a combination of on / off of each bit. In the
case where the LED is turned off, the lighting time represented by the lighting control data is
zero. That is, on is not set to any bit.
[0046]
10-04-2019
14
For example, in FIG. 5B, the red LED (R) is turned on for 4 bits of lighting time, the green LED (G)
is turned on for 3 bits of lighting time, and the blue LED (R) is turned on. An example of a pattern
of on / off timing is shown in which B) is turned on for a lighting time of 2 bits. As the lighting
time of the LED per 1.5 ms period is longer, the amount of light when blinking on the lighting
cycle every 12 ms increases, so the luminance of the LED becomes higher, and conversely, the
LED per 1.5 ms period As the lighting time is shorter, the amount of light when blinking in the
lighting cycle every 12 ms is smaller, so the luminance of the LED is lower. That is, the luminance
for lighting the LED is determined according to the lighting time of the LED represented by the
lighting control data.
[0047]
By the way, from the point of view of control of lighting time, the timings of ON / OFF of the LED
in the 1.5 ms period are different, and the patterns of the on / off timing with the same lighting
time are distinguished. There is no need. Therefore, in the present embodiment, as shown in FIG.
6, six time patterns having different lighting times are determined in advance, and any one of the
six time patterns shown in FIG. 6 is used as lighting control data for each LED. The time pattern
of is assumed to be set.
[0048]
In FIG. 6, “pattern 6” is a time pattern in which all 6 bits are set to ON, “pattern 5” is a time
pattern in which 5 bits of 6 bits are set to ON, and “pattern 4” is 6 Of the bits, a time pattern in
which 4 bits are set to ON, a “pattern 3” is a time pattern in which 3 bits of 6 bits are set to
ON, and “Pattern 2” is set to 2 bits of 6 bits ON The “time pattern” and the “pattern 1”
are time patterns in which one of six bits is set to on. In these six time patterns “pattern 6” to
“pattern 1”, “pattern 6” is the pattern with the highest brightness (bright), and the
brightness becomes 1 as the lighting time decreases by one step in the order of the numbers.
Step by step. "Pattern 1" is the pattern with the lowest luminance (dark).
[0049]
In the ROM 22 or the RAM 23, any one time pattern of "pattern 1" to "pattern 6" shown in FIG. 6
10-04-2019
15
is stored as the current value of the lighting control data for each LED. The lighting control data
stored in the ROM 22 or the RAM 23 is, in principle, the red LED for the multicolor LED unit 10
incorporated in each of the plurality of LED buttons 9, the green LED, and the ROM 22 for each
blue LED. It is stored in the RAM 23. This is because lighting control of each of the multicolor
LED units 10 is performed for each LED based on lighting control data for each of the red LED,
the green LED, and the blue LED.
[0050]
On the other hand, for the push button switch 6 (LED button 9) of each channel strip of the
channel strip section 3 in FIG. 1, exceptionally, each LED of each physical LED button 9 and
lighting control data correspond one to one. Rather, the lighting control data for each LED of the
LED button 9 of the channel strip is stored in the ROM 22 or the RAM 23 for each channel
allocated to the channel strip. The lighting state of the LED button 9 of each channel strip (for
example, the lighting on / off state of the LED button 9, the emission color of the LED button 9,
etc.) differs depending on the channel currently assigned to that channel strip. It is. For example,
if channel number "1" or "17" can be assigned to a certain channel strip, lighting for channel
number "1" corresponding to one physical LED button 9 provided for that channel strip Two
lighting control data of the control data and the lighting control data for the channel number
"17" are stored in the ROM 22 or the RAM 23.
[0051]
Next, an example of the operation method for adjusting the luminance of the LED button 9 and
an example of the operation method for adjusting the color combination of the LED button 9 will
be described. First, the user operates either the brightness adjustment mode selection button
(Brightness) 15 or the color matching adjustment mode selection button (Color) 16 to change the
operation mode from the normal mode to either the brightness adjusting mode or the color
matching adjustment mode. Switch.
[0052]
FIG. 7 is a flow chart for explaining the procedure of processing executed by the CPU 21 to set
the luminance adjustment mode or the color matching adjustment mode to ON. The processing in
FIG. 7 is activated when either the brightness adjustment mode selection button 15 or the color
10-04-2019
16
matching adjustment mode selection button 16 is operated to turn on the brightness adjustment
mode or the color matching adjustment mode. When either the brightness adjustment mode
selection button 15 or the color matching adjustment mode selection button 16 is operated, the
CPU 21 determines that the operated button is either the brightness adjustment mode selection
button 15 or the color matching adjustment mode selection button 16 It is determined (step S1).
If the operated button is the brightness adjustment mode selection button 15, the CPU 21 sets
the brightness adjustment mode to ON (step S2). If the operated button is the color matching
adjustment mode selection button 16, the CPU 21 sets the color matching adjustment mode to on
(step S3).
[0053]
When the normal operation mode is on, both the brightness adjustment mode and the color
adjustment mode are off. In this state, when either the brightness adjustment mode selection
button 15 or the color adjustment mode selection button 16 is operated, the CPU 21 operates the
operation mode of the sound adjustment console 1 in step S2 or step S3. Switch to the brightness
adjustment mode or the color adjustment mode corresponding to 15 or 16.
[0054]
The on / off state of the luminance adjustment mode selection button 15 or the color matching
adjustment mode selection button 16 is switched every one operation, and only one of them is
exclusively turned on. Therefore, when one of the buttons 15 or 16 is on and the other off button
is operated, the mode corresponding to the operated button switches from off to on in step S2 or
step S3. At the same time, the mode that was on until the last switch is switched off. When one of
the brightness adjustment mode and the color adjustment mode is on and the button 15 or 16
corresponding to the on mode is operated, the mode is switched from on to off, and the operation
mode is normally Switch to mode.
[0055]
<< Brightness adjustment mode >> When adjusting the brightness (brightness) of the LED button
9, the user first operates the brightness adjustment mode selection button (Brightness) 15 to set
the brightness adjustment mode by the process of FIG. turn on. Then, using the adjustment target
designation buttons 17, 18, 19 and 20, the color (LED) to be adjusted is designated, and the LED
10-04-2019
17
button 9 is operated to operate the multicolor LED unit 10 corresponding to the operated LED
button 9. Adjust the brightness for the color to be adjusted (LED).
[0056]
FIG. 8 is a flowchart for explaining the procedure of processing executed by the CPU 21 to
designate a color (LED) to be adjusted. The processing in FIG. 8 is activated when any one of the
adjustment target designation buttons 17, 18, 19 and 20 is operated in the state where the
brightness adjustment mode or the color matching adjustment mode is on. That is, the operations
of the adjustment target designation buttons 17, 18, 19 and 20 are effective only when the
luminance adjustment mode or the color matching adjustment mode is on. If the operation mode
is the normal mode, the target color designation operation is not performed.
[0057]
When one of the adjustment target designation buttons 17, 18, 19 and 20 is operated, the CPU
21 determines which of the adjustment target designation buttons 17, 18, 19 and 20 is the
operated button (Step S4). When the operated adjustment target designation button is a button
17, 18 or 19 for designating red (R), green (G) or blue (B), the CPU 21 adjusts the LED of the
designated color (Step S5). When the operated adjustment target designation button is the button
20 for designating all colors (ALL), the CPU 21 sets LEDs of all colors of RGB as adjustment
targets (step S6). It is assumed that only one of the adjustment target designation buttons 17, 18,
19 and 20 is exclusively turned on. Therefore, when a new adjustment target is set in step S5 or
S6, the color designated as the adjustment target until immediately before is not the adjustment
target.
[0058]
The user designates the color to be adjusted (LED) using the adjustment object designation
buttons 17, 18, 19 and 20, and then operates the LED button 9 to operate the multicolor LED
unit corresponding to the operated LED button 9. Adjust the brightness for the color to be
adjusted (LED) in 10).
[0059]
10-04-2019
18
FIG. 9 is a flowchart for explaining the procedure of processing executed by the CPU 21 in order
to change the luminance of the color (LED) designated as the adjustment target in the luminance
adjustment mode.
The process of FIG. 9 is activated each time the user presses the LED button 9 corresponding to
the multicolor LED unit 10 which performs the brightness adjustment. When the LED button 9 is
operated, the CPU 21 controls the color (LED) to be adjusted designated in the process of FIG. 8
to be any one of red (R), green (G) and blue (B). It is determined whether it is or all colors (ALL)
(step S7). This is because subsequent processing differs depending on whether the designated
adjustment target is one color or all colors.
[0060]
When the designated adjustment target is any one color (one LED) of red (R), green (G), or blue
(B), the CPU 21 is a multicolor LED unit corresponding to the operated LED button 9 The value
(time pattern) of the lighting control data for the color to be adjusted (LED) in 10 is acquired
from the ROM 22 or the RAM 23 (step S8). For example, when red is designated as the
adjustment target, the current value of the lighting control data for the red LED in the multicolor
LED unit 10 corresponding to the operated LED button 9 is acquired from the ROM 22 or the
RAM 23. The current value of the lighting control data acquired here corresponds to the
luminance of the color in the multi-color LED unit 10 at the present time.
[0061]
Then, the CPU 21 changes the value of the lighting control data for the color to be adjusted (LED)
acquired in step S8 to a time pattern (see FIG. 6) having a high one-step luminance (step S9). The
CPU 21 rewrites the stored contents of the ROM 22 or the RAM 23 in accordance with the
change of the value of the lighting control data. Thereby, the brightness of the color (LED) to be
adjusted in the multicolor LED unit 10 corresponding to the operated LED button 9 is increased
by one level.
[0062]
When the designated adjustment target is all colors (three LEDs), the CPU 21 controls the
10-04-2019
19
lighting control data for the three LEDs constituting the multicolor LED unit 10 corresponding to
the operated LED button 9 by using the ROM 22 or the RAM 23. (Step S10). Then, the CPU 21
changes the value of each lighting control data for each LED acquired in step S10 into a pattern
with high (bright) one-step luminance (step S11). The CPU 21 rewrites the stored contents of the
ROM 22 or the RAM 23 in accordance with the change of the value of the lighting control data.
Thereby, the values of the lighting control data for the three LEDs of the multicolor LED unit 10
corresponding to the operated LED button 9 are simultaneously changed to increase the
brightness (brightness) of the multicolor LED unit 10 by one step. . That is, the difference
between step S10 and step S11, and the difference between step S8 and step S9 is processing of
the lighting control data for one color designated as the adjustment target, or lighting control for
all colors (for three LEDs) The point is whether to process data.
[0063]
<< Method of Operating the LED Buttons One by One >> In the brightness adjustment mode, an
example of the operation method of adjusting the brightness of the LEDs is the operation of the
LED button 9 itself having the color (LED) to be adjusted. There is a method of adjusting the
brightness of the color to be adjusted (LED) in the multicolor LED unit 10 incorporated in FIG. In
this case, the multicolor LED unit 10 incorporated in the operated LED button 9 corresponds to
the “multicolor LED unit 10 corresponding to the LED button 9”. The user can adjust the
brightness of each LED in the multicolor LED unit 10 incorporated in the LED button 9 one by
one individually with respect to the plurality of LED buttons 9 provided on the sound adjustment
console 1.
[0064]
When the adjustment target is designated one by one (when the adjustment target designation
button 17, 18 or 19 is turned on), the CPU 21 presses the LED button 9 once while visually
recognizing how the luminance is changed. And S9, the brightness of the color to be adjusted is
increased by one step. When the color (LED) designated as the adjustment target becomes a
desired brightness by the operation of the LED button 9, the user ends the operation of the LED
button 9. By performing this operation for a plurality of LED buttons 9, it is possible to obtain
user's favorite brightness for each LED of each LED button 9. According to this method, for
example, the luminance of another LED button 9 is adjusted for each LED with reference to the
luminance of a certain LED button 9, whereby variations in luminance of individual LEDs among
a plurality of LED buttons 9 are generated. Can be corrected.
10-04-2019
20
[0065]
When all the colors are designated as the adjustment target (when the adjustment target
designation button 20 is turned on), the CPU 21 executes steps S10 and S11 each time the LED
button 9 is operated once. The brightness of all the LEDs of the multicolor LED unit 10
incorporated in the LED button 9 is increased by one step. Therefore, in this case, the user can
adjust the overall brightness of the multicolor LED unit 10 to change the brightness of the
multicolor LED unit 10. When the LED button 9 has a desired brightness, the operation of the
LED button 9 is ended. By performing this operation on a plurality of LED buttons 9, it is possible
to obtain the user's favorite brightness for each of the LED buttons 9. This method is suitable
when it is desired to correct the variation in luminance of the entire multicolor LED unit 10
among the plurality of LED buttons 9.
[0066]
<< Method Using Channel Selection Button >> As another example of the operation method in the
luminance adjustment mode, there is a method of changing the luminance using the channel
selection button 8 of the control section 7. As described above, the channel selection button 8
functions as a button for selecting a channel group to be assigned to a plurality of channel strips
of the channel strip section 3 in the normal operation mode. On the other hand, when the
brightness adjustment mode is on, the channel selection button 8 is an adjustment target for the
multicolor LED unit 10 incorporated in the LED button 9 (push button switch 6) provided for
each channel strip of the channel strip section. It functions as a button for adjusting the
brightness of the color to be adjusted (LED) designated by the designation buttons 17, 18, 19
and 20.
[0067]
When adjusting the brightness using the channel selection button 8, the CPU 21 controls the
color designated as the adjustment target (LED for one color or LED for all colors) every time the
channel selection button 8 is operated once. The values of LED lighting control data (that is, a
plurality of lighting control data for a plurality of channels) set for each channel belonging to the
channel group corresponding to the operated channel selection button 8 are acquired from the
ROM 22 or the RAM 23, The value of each acquired lighting control data is changed to a time
pattern having a high one-step luminance. In this case, the multicolor LED unit 10 incorporated
10-04-2019
21
in the LED button 9 (push button switch 6) of each channel strip of the channel strip section
corresponds to the "multicolor LED unit 10 corresponding to the operated LED button 9". It will
correspond to
[0068]
Therefore, every time the user operates the channel selection button 8, the brightness of the LED
button 9 (push button switch 6) of each channel strip currently emitted at that time can be
simultaneously brightened one by one. it can. That is, by operating one channel selection button
8, the color (the LED for one color) or the adjustment target color is collectively obtained for a
plurality of LED buttons 9 (push button switches 6) other than the channel selection button 8. It
is possible to adjust the brightness of the LEDs for all colors. By performing this operation on a
plurality of channel selection buttons 8, it is possible to adjust the brightness of the LED button 9
(push button switch 6) when calling each channel corresponding to each channel selection
button 8 to the channel strip. . Here, it is assumed that the channel selection button 8
corresponding to the channel group assigned to each channel strip of the channel strip section at
that time is operated. This is because it is natural to perform the brightness adjustment of the
LED while visually recognizing the lighting condition of the LED button 9 currently lit.
[0069]
When the luminance is adjusted using a channel selection button 8 other than the channel
selection button 8 (the one in the on state) corresponding to the channel group currently
assigned to the channel strip section 3, for example, After the channel group assigned to the
channel strip section 3 is switched by the first operation, the brightness adjustment may be
started after the next operation.
[0070]
As described above, in the “brightness adjustment mode”, the brightness of each of the LEDs
11 to 13 constituting the multicolor LED unit 10 is set for each of the LED buttons 9
incorporating the multicolor LED unit 10 in the acoustic control console. There is an excellent
effect that it can be adjusted by operation.
Along with this, for example, the brightness of another LED button 9 can be adjusted for each
LED based on the brightness of a certain LED button 9, or the variation of the brightness among
10-04-2019
22
the plurality of LED buttons 9 can be easily made. It will be possible to fix it. Furthermore, this
brightness adjustment operation can be performed by activating the brightness adjustment mode
and specifying the color to be adjusted, and then operating the operation element corresponding
to the multicolor LED unit 10 for which the brightness adjustment is desired Because it can, it
can be done in a concise and easy-to-understand manner. Further, since a mechanism or the like
for automatically measuring the lighting condition of the LED is unnecessary, the function of
adjusting the brightness can be realized without cost.
[0071]
<< Color Adjustment Mode >> Next, the “color adjustment mode” will be described. When
adjusting the color combination (hue) of the LED button 9, the user first operates the color
adjustment mode selection button 16 to turn on the color adjustment mode (the process of FIG.
7). Then, the user operates one of the adjustment target designation buttons 17, 18, 19 and 20 to
designate a color (LED) to be adjusted, operates the LED button 9, and corresponds to the
operated LED button 9. The coloration of the color to be adjusted (LED) in the multicolor LED
unit 10 is adjusted. The process for designating the color to be adjusted, which is executed by the
CPU 21 in accordance with the operation of the adjustment target designation buttons 17, 18, 19
and 20, is the same as that described with reference to FIG. And I omit the explanation.
[0072]
In the color adjustment mode, in accordance with the operation of the LED button 9, the
luminance of the color (LED) designated as the adjustment target in the multicolor LED unit 10
corresponding to the LED button 9 is increased, and the other colors (LED The RGB balance of
the multi-color LED unit 10 is changed by lowering the luminance of), thereby adjusting the
coloration of the emission color of the multi-color LED unit 10 (LED button 9). FIG. 10 is a view
for explaining how the RGB balance changes when changing the color combination of the light
emission color of the multicolor LED unit 10 in the color adjustment mode.
[0073]
In FIG. 10, assuming that the LEDs of each color in the multicolor LED unit 10 are lit with
maximum luminance at 100%, (a) shows that the red LED (R) of the multicolor LED unit 10 is 70
%, The green LED (G) is 20%, and the blue LED (B) is lit at a luminance of 50%. In this state, when
10-04-2019
23
red is designated as the color to be adjusted, the balance of RGB changes from the state of (a) to
the state of (b) according to the operation of the LED button 9. In (b), the luminance of the red to
be adjusted is 10% higher than in (a), and the luminances of the other green and blue are each
10% lower. As a result, the color combination of the light emission color changes in the direction
in which redness intensifies as the entire multicolor LED unit 10. Thus, according to the
operation of the LED button 9, changing the RGB balance of the multicolor LED unit 10, that is,
changing the luminance ratio of the red LED, the green LED, and the blue LED The coloration of
the light emission color of the multicolor LED unit 10 can be arbitrarily created or adjusted. In
addition, in this specification, a "coloring" is taken as the term which points out the color (hue)
created by combination of each color of LED for red, LED for green, and LED for blue.
[0074]
FIG. 11 is a flowchart for explaining the procedure of processing executed by the CPU 21 in
order to change the color combination of the color (LED) designated as the adjustment target in
the color adjustment mode. The process of FIG. 11 is activated each time the user presses the
LED button 9 corresponding to the multicolor LED unit 10 which performs color matching. The
CPU 21 determines whether the color to be adjusted (LED) designated in the process of FIG. 8 is
any one color of red (R), green (G) or blue (B), or all colors (LED It is determined whether it is
ALL) (step S12). This is because subsequent processing differs depending on whether the
designated adjustment target is one color or all colors.
[0075]
When the adjustment target is designated one by one (when the adjustment target designation
button 17, 18 or 19 is turned on), the CPU 21 controls the adjustment target in the multicolor
LED unit 10 corresponding to the operated LED button 9 Change the value of lighting control
data for color (LED) to a pattern with high one-step luminance (step S13), and change the value
of lighting control data for colors other than adjustment target (LED) to a pattern with one lowstep luminance It changes (Step S14). The CPU 21 rewrites the stored contents of the ROM 22 or
the RAM 23 in accordance with the change of the value of the lighting control data. That is, every
time the LED button 9 is operated once, the CPU 21 executes steps S13 and S14 to designate the
adjustment target in the multicolor LED unit 10 corresponding to the LED button 9 operated by
the user. The ratio of the luminance of the LEDs constituting the multicolor LED unit 10 is
changed so that the luminance of the selected color (LED) becomes relatively high (see FIG. 10).
10-04-2019
24
[0076]
In the color adjustment mode, the luminance of the LED corresponding to the color designated as
the adjustment target is made relatively high, and the ratio of the luminance of the plurality of
LEDs constituting the multicolor LED unit 10 is changed. Since the purpose is to adjust the
coloration for the designated color, in principle, there is no use of the adjustment target
designation button 20 (the designation of all the colors as the adjustment target). In such a case,
the overall brightness is increased without changing the color combination of the light emission
color of the multicolor LED unit 10. However, since this relates to the method of use by the user,
the processing executed by the CPU 21 when the adjustment target designation button 20 is
operated is depicted in FIG. That is, when all the colors are designated as the adjustment target
(when the adjustment target designation button 20 is turned on), the CPU 21 controls the three
LEDs constituting the multicolor LED unit 10 corresponding to the operated LED button 9 A
process is performed to change the value of the lighting control data for (all colors of red (R),
green (G) and blue (B)) to a pattern having a high one-step luminance (step S15). The brightness
of unit 10 is generally increased.
[0077]
The operation method in the color adjustment mode is a method of adjusting the color
combination of the multicolor LED unit 10 incorporated in the operated LED button 9 in
accordance with the operation of the LED button 9 as described in the above-mentioned
brightness adjustment mode. (Method of operating the LED button 9 one by one) and method of
changing the color combination of the multicolor LED unit 10 incorporated in the LED button 9
of each channel strip of the channel strip section according to the operation of the channel
selection button 8 Any method (method using the channel selection button 8) is possible.
[0078]
In the case of "the method of operating the LED button 9 one by one", the CPU 21 executes steps
S13 and S14 each time the user operates the LED button 9 one time, thereby changing the color
combination of the LED button 9 Be done.
The user visually recognizes the degree of change in coloration and adjusts the coloration of the
LED button 9 while changing the color of the adjustment target as necessary. When the LED
button 9 has a desired color combination, the operation of the LED button 9 is ended. By
performing this operation for a plurality of LED buttons 9, it is possible to obtain the user's
10-04-2019
25
favorite color combination for each of the LED buttons 9. That is, for each of the LED buttons 9,
the light emission color can be set to any color combination.
[0079]
Further, in the case of the “method using the channel selection button 8”, the CPU 21 controls
the color designated as the adjustment target (LED for one color or LED for all colors) each time
the channel selection button 8 is operated once. The values of lighting control data (that is, a
plurality of lighting control data for a plurality of channels) for the LED set for each channel
belonging to the channel group corresponding to the operated channel selection button 8 are
acquired from the ROM 22 or the RAM 23 Change the value of each acquired lighting control
data to a time pattern having a high one-step luminance (step S13), and change the value of
lighting control data for colors (LEDs) other than the adjustment target to one-step luminance Is
changed to a low time pattern (step S14). In this case, the multicolor LED unit 10 incorporated in
the LED button 9 (push button switch 6) of each channel strip of the channel strip section
corresponds to the "multicolor LED unit 10 corresponding to the operated LED button 9". It
corresponds to
[0080]
Therefore, each time the user operates the channel selection button 8, the color combination of
the LED button 9 (the push button switch 6) of each channel strip currently being emitted at that
time is changed. That is, the user operates one channel selection button 8 to collectively adjust
the colors (one color) of the plurality of LED buttons 9 (push button switches 6) different from
the channel selection button 8 in a batch. Adjustment of the color of the LED). Here, although it is
assumed that the channel selection button 8 corresponding to the channel group assigned to
each channel strip of the channel strip section at that time is operated, the same as the
brightness adjustment described above In addition, it is also possible to perform color matching
using a button 8 other than the channel selection button 8 (the one in the on state)
corresponding to the channel group currently assigned to the channel strip section 3.
[0081]
As described above, in the “color adjustment mode”, for each LED button 9 incorporating the
multicolor LED unit 10, the color combination of the light emission color is optionally created by
10-04-2019
26
the user operation, or the color combination is performed by the user operation It has the
excellent effect of being able to be adjusted. Along with this, it becomes possible for the user to
set the light emission color of each of the LED buttons 9 independently, and an environment easy
for the user to operate can be created. In addition, since the color adjustment is performed for
each LED by designating the color to be adjusted, it is possible to easily correct the color
variation among a plurality of LED operators caused by the variation of the light emission
characteristic of each LED. Can. Furthermore, this color adjustment operation can be performed
only by activating the color adjustment mode and designating the color to be adjusted, and then
operating the operation element corresponding to the multicolor LED unit for which color
adjustment is desired to be performed. So it can be done in a concise and easy to understand
way.
[0082]
In FIG. 6, six patterns of lighting control data of 6 bits are determined in advance, and in the
“brightness adjustment mode” and the “color adjustment mode”, each pattern of the LED
button 9 is operated. Although an example in which six time patterns are sequentially switched
has been described, all 64 patterns that can be expressed by 6-bit lighting control data may be
used. In short, the brightness of the LED corresponding to the lighting control data may be
changed by changing the lighting time represented by the lighting control data. Further, the size
(number of bits) of the lighting control data is not limited to 6 bits.
[0083]
Further, in the process of changing the lighting control data in step S9 and step S11 of FIG. 9
above to the one with high brightness one step at a time in the brightness adjustment mode,
when the lighting control data reaches the maximum value, the LED button thereafter The
operation of 9 may be configured to be invalid (the value does not change after that), or may be
configured to return to the minimum value.
[0084]
Further, with regard to the color matching adjustment mode, in steps S13 and S15 of FIG. 11
above, the lighting control data of the color to be adjusted is changed one step at a time to a high
luminance one for each operation of the LED button 9 In this process, the lighting control data is
changed one step at a time to low luminance, but the lighting control data for the color to be
adjusted is not limited to the configuration in which the color to be adjusted is strengthened at
10-04-2019
27
the same time other colors are weakened. It may be configured to perform only the process of
changing the value of V in one step into the one with high brightness (process of intensifying the
color to be adjusted).
Also, in this case, after the lighting control data for the color to be adjusted reaches the maximum
value, the lighting control data for the colors other than the color to be adjusted is lowered by
one step to lower luminance (that is, the colors other than the color to be adjusted are weakened)
) May be configured.
[0085]
Further, in FIG. 3, in the control section 7, a configuration example in which a luminance
adjustment mode selection button 15, a color matching adjustment mode selection button 16,
and adjustment target designation buttons 17, 18, 19 and 20 are provided. An example of the
configuration in which an operator related to luminance adjustment or color adjustment is
provided as a physical operator has been shown. However, the operators 15 to 20 involved in the
brightness adjustment or the color adjustment of the LED buttons 9 are not limited to those
provided as physical operators on the operation panel, but the LCD display 2 An image of an
operator related to luminance adjustment or color adjustment may be displayed, and may be
configured by an operator image related to luminance adjustment of the LED button 9 or color
adjustment.
[0086]
Further, in the above embodiment, the lighting time of the LED to be adjusted is changed by
changing the time pattern represented by the lighting control data in accordance with the
operation of the LED button 9, whereby the multicolor LED unit 10 is changed. Although the
configuration example in which the brightness or the coloration is changed, that is, the
configuration example in which the brightness of the LED is changed by changing the time
pattern without changing the voltage value of the lighting control data, the invention is not
limited thereto. The voltage value of the lighting control data may be changed according to the
operation of the button 9 to change the luminance or the color combination of the multicolor
LED unit 10. In this case, each of the LEDs 11 to 13 of the multicolor LED unit 10 is controlled to
light at a luminance according to the voltage value indicated by the corresponding lighting
control data. Then, in the case of the brightness adjustment, the CPU 21 executes the processing
corresponding to the steps S8 and S9 or the steps S10 and S11 of FIG. 9 according to the user's
10-04-2019
28
operation, and in the case of the color adjustment, the above By executing the processing
corresponding to steps S13 and S14 in FIG. 11, the voltage value indicated by the lighting control
data for the LED to be adjusted is changed, and the luminance of the LED is adjusted. Even with
this configuration, it is possible to change the luminance or coloration of the multicolor LED unit
10. The change of the voltage value is performed, for example, in such a manner that the voltage
value increases stepwise by 10% each time the LED button 9 is operated.
[0087]
Further, by providing an operator that allows the user to select whether to change the time
pattern of the lighting control data or to change the voltage value according to the operation of
the LED button 9, the time pattern indicated by the lighting control data can be obtained. The
user may select whether to change or change the voltage value. As a specific configuration
example, an operator for selecting to change the pattern of lighting control data and an operator
for selecting to change the voltage value are provided on the operation panel such as the control
section of FIG. Alternatively, they may be provided as physical operators, or they may be
configured by an operator image displayed on the LCD display 2. In addition, when an operator
selects to change the pattern of lighting control data and an operator selects to change the
voltage value, when those operators are provided, the luminance adjustment mode selection
button 15 and the color adjustment adjustment mode selection button 16 may not be provided.
In this case, an instruction to turn on the brightness adjustment mode or the color matching
adjustment mode substantially includes an operator selecting to change the pattern of the
lighting control data, and an operator selecting to change the voltage value. It is because it can
carry out using.

Further, in the above embodiment, the LED button 9 comprising a push button switch
incorporating a multicolor LED unit is illustrated as an example of the configuration of the LED
operator (see FIG. 2), but the configuration of the LED operator is It is not limited. That is, the
operation mode of the LED button 9 is not limited to the push button switch shown in the above
embodiment, but any type of operation element such as a knob type operation element operated
in a rotary manner or a level operation body operated in a slide manner. Even the present
invention can be applied. If it is a knob type operation element, the brightness or color
combination of the corresponding multicolor LED unit 10 may be changed according to the
rotation position or rotation operation, and it corresponds according to the operation position or
slide operation of the fader type operation element. The luminance or color combination of the

multicolor LED unit 10 may be changed. Further, the LED operators are not limited to the selfillumination type operators incorporated in the operators themselves corresponding to the
multicolor LED unit 10, but for example, those provided in the vicinity of the operators, etc. in
the present invention It is included in "LED Controller with built-in multi-color LED unit".
[0089]
Further, in the above embodiment, it has been described that only one of the adjustment target
designation buttons 17, 18, 19 and 20 is exclusively turned on. However, the adjustment target
designation for specifying the adjustment target for each color is described. For buttons 17, 18
and 19, one or more may be able to be turned on simultaneously. That is, two colors may be
designated as adjustment targets. In this case, the CPU 21 sets the LEDs corresponding to the
two designated colors in the step S5 as the adjustment target, and in the case of the luminance
adjustment mode, each of the designated two colors in the steps S8 and S9. Change lighting
control data to one with high brightness. Further, in the case of the color adjustment mode, the
CPU 21 increases the brightness of each lighting control data for the two designated colors in the
steps S13 and S14, and lights the LEDs corresponding to colors other than the designated color.
Decrease the brightness represented by the control data.
[0090]
Further, in the above embodiment, the configuration is described in which the brightness or the
color combination of the multicolor LED unit 10 is adjusted by operating the LED button 9 itself
corresponding to the multicolor LED unit 10 for which the brightness or the color combination is
desired to be adjusted. In this case, for adjustment for each color, it is necessary to designate one
of the three colors of LEDs in the multicolor LED unit 10. Another configuration example
regarding this point is shown in FIG. FIG. 12 shows a modification of the control section 7 shown
in FIG. 12, in place of the adjustment target designation buttons 17 to 20 shown in FIG. 3, three
luminance or color tone adjustment operators 40, 41 and 42 corresponding to the three colors of
LEDs are provided. The operating elements 40, 41 and 42 are constituted by, for example, a knob
type operating element (rotary encoder) which is operated to be rotated. In this case, when the
user designates the LED button 9 corresponding to the multicolor LED unit 10 whose brightness
or coloration is desired to be adjusted in the brightness adjustment mode or the color adjustment
mode, the CPU 21 designates the LED button 9 according to the designated operation. A process
of assigning lighting control data for three LEDs of the multicolor LED unit 10 corresponding to
the LED button 9 to the corresponding luminance or color setting adjustment operators 40, 41
and 42 is performed. Then, the CPU 21 changes the luminance represented by the lighting
10-04-2019

control data assigned to each of the operators 40, 41 and 42 in accordance with the operation of
each of the three luminance or color combination adjustment operators 40, 41 and 42. Thereby,
the user can individually adjust the luminance or the color combination of the three-color LEDs
of the multicolor LED unit 10 corresponding to the designated LED button 9. As an example of
the operation method in the case where the LED button 9 is a push button switch, the LED button
9 is kept pressed and the LED button 9 is operated by operating the operators 40, 41 and 42 for
adjusting brightness or color combination. It is possible to perform brightness or color
adjustment, and releasing the LED button 9 can end the brightness or color adjustment of the
LED button 9. Furthermore, in this case, the lighting control data for the three color LEDs are
collectively assigned to any one of the luminance or color matching adjustment operators 40, 41
and 42 to operate the brightness or color matching adjustment operators. Accordingly, the
brightness or color combination of the three color LEDs may be able to be adjusted collectively.
The operation form of the three luminance or color adjustment operators corresponding to each
color of the three color LEDs is not limited to the knob type operator but may be any form such
as a push button switch or a fader type operator. It may be.
In addition, the present invention is not limited to the configuration in which dedicated operators
are provided as the brightness or color adjustment operators 40, 41 and 42, but the operators
originally intended for other applications are in the brightness adjustment mode or the color
adjustment mode , And may be configured to function as the operators 40, 41 and 42 for
adjusting the brightness or the color combination.
[0091]
Also, in the “method using the channel selection button 8” described as another example of
the operation method in the luminance adjustment mode or the color matching adjustment mode,
an example in which the user operates the “channel selection button 8” has been described.
The operating elements to be used are not limited to the “channel selection button 8”, and the
brightness adjustment or the color matching adjustment is performed for a plurality of
predetermined LED buttons 9 different from the operated operating element according to the
operation of the operating element by the user. It does not matter which operator is used.
Further, in this method, since the luminance or the color combination is adjusted for a plurality
of LED buttons 9 other than the operator operated by the user, the operator operated by the user
does not have to be the LED button 9 itself.
