[0011]
<1. Embodiment> "Overview of Embodiment" First, an overview of an embodiment in the
present disclosure will be described. In one embodiment of the present disclosure, for example,
the reproduction volume of the audio content reproduced from the speaker is changed according
to the position at which the user is present and the brightness of the illumination. FIG. 1A shows
an example of a room R of a user U. A light L is disposed on the ceiling of the room R. In the
room R, a bed B, which is an example of bedding, is installed. The bedding may be a futon.
[0012]
Although the details will be described later, the illumination L is integrally configured with an
imaging device for imaging a position including the bed B and a reproduction device for
reproducing audio content. Therefore, the audio content is reproduced from the vicinity of the
arrangement position of the illumination L toward the room of the room R. The mark of the note
shown in FIG. 1A schematically shows that the audio content is being reproduced in the room R.
The size of the mark of the note schematically indicates the size of the reproduction volume of
the audio content. The larger the size of the note mark, the larger the reproduction volume of the
audio content.
[0013]
During playback of the audio content, the brightness of the illumination is controlled such that
the brightness of the illumination is less than or equal to a predetermined brightness. In the
example of FIG. 1A, since the user U is at a position different from the position of the bed, no
person is detected from the captured image acquired by the imaging device. In such a case, the
user U is determined to listen to the audio content in the dark, and the reproduction volume of
the audio content is not controlled.
[0014]
On the other hand, in the example of FIG. 1B, the user U lies on the bed B during the
reproduction of the audio content. The user U who is a person is detected from the captured
image acquired by the imaging device. In such a case, it is determined that the user U goes to
11-04-2019
4
bed, and the reproduction mode of the audio content is changed. For example, the playback
volume of the audio content being played back is reduced. Thus, in one embodiment of the
present disclosure, the playback volume of the audio content is controlled according to the
position of the user and the brightness of the illumination. Hereinafter, the contents of an
embodiment of the present disclosure will be described in detail.
[0015]
"An example of a system" Drawing 2 shows an example of composition of a system in one
embodiment. The system 1 includes, for example, a playback device 100, a home server 200, and
a portable terminal 300. For example, the playback device 100 is integrally configured with the
lighting device 110 and the imaging device 120, and is attached to the ceiling of a room. The
home server 200 is placed at a predetermined position in the room. The home server 200 has,
for example, a portable size and weight. The portable terminal 300 is carried by the user. The
portable terminal 300 can be used to control the playback device 100, the home server 200, and
the like. Each device will be described in detail below.
[0016]
The playback device 100 is attached, for example, near the center of the ceiling of the room. The
playback device 100 includes a columnar casing 10 standing upright toward the room from
approximately the center of the ceiling. Wiring or the like for supplying power to the playback
device 100, the lighting device 110, and the imaging device 120 is housed inside the housing 10.
For example, power based on a commercial power supply is supplied to the playback device 100,
the lighting device 110, and the imaging device 120.
[0017]
For example, two speakers SP are disposed on each side surface of the housing 10. The playback
device 100 has eight speakers SP. The position and the number of the speakers SP can be
changed as appropriate. The light emitting unit 111 of the lighting device 110 is attached to the
end face of the housing 10. The imaging unit 121 of the imaging device 120 stands upright
toward the room from substantially the center of the lighting device 110. The imaging unit 121
is configured, for example, as an omnidirectional imaging optical system capable of imaging an
object present in all directions (0 ° to 360 °), and configured to be able to image the inside of a
11-04-2019
5
room.
[0018]
The home server 200 accumulates content data. The content data is, for example, audio content.
It may be video content or still image content such as a photo. The content data accumulated in
the home server 200 is supplied to the reproduction device 100 via the network and reproduced
by the reproduction device 100. The home server 200 may have other functions such as a
function as a personal computer and a function as a game machine.
[0019]
The mobile terminal 300 is, for example, a smartphone. The portable terminal 300 may be a
tablet computer or a dedicated remote control device usable in the system 1. For example, by
downloading a predetermined application to the mobile terminal 300 and executing the
application, control using the mobile terminal 300 can be performed on a plurality of electronic
devices.
[0020]
When an operation is performed on the portable terminal 300, a control signal corresponding to
the operation is generated. A control signal is sent to the reproduction device 100 or the like, and
the reproduction device 100 or the like operates according to the control signal. The control
signal transmitted from the portable terminal 300 is transmitted, for example, wirelessly. The
control signal sent from the portable terminal 300 may be transmitted by infrared light.
[0021]
The following control is exemplified as control for the electronic device using the portable
terminal 300. For example, the home server 200 can be controlled to select audio content to be
reproduced. For example, control for adjusting the playback volume of the audio content played
back from the playback device 100 can be performed on the playback device 100. For example,
control for adjusting the brightness of the light emitting unit 111 of the lighting device 110 can
11-04-2019
6
be performed on the lighting device 110.
[0022]
Each device constituting the system 1 corresponds to, for example, Digital Living Network
Alliance (DLNA). The DLNA is one specification for building a home network in which a plurality
of electronic devices on the network are connected. By DLNA, digital AV (Audio Visual) devices
and personal computers are mutually connected by a home network, and specifications
(guidelines) for mutually using contents such as moving images, music, still images, etc. are
formulated. In the specifications of DLNA, the following devices are defined as devices (referred
to as devices).
[0023]
DMS (Digital Media Server): A content supply unit that provides content. It is called a server. DMP
(Digital Media Player): A control playback unit having an interface function and a content
playback function. DMR (Digital Media Renderer): A reproduction unit having a function of
reproducing content stored in the DMS or content transmitted from the DMS side under control
of the DMC described later. It is called a renderer. DMC (Digital Media Controller): A control
function unit that controls DMP, DMR, etc. to perform necessary playback control.
[0024]
In the example of system 1, the playback device 100 functions as a DMR. The home server 200
functions as DMS and DMP. The portable terminal 300 functions as a DMC.
[0025]
[One Example of Configuration of Reproducing Device Etc.] Next, an example of the configuration
of each of the reproducing device 100, the illumination device 110, and the imaging device 120
(appropriately referred to as the reproducing device 100 etc.) will be described. The reproduction
device 100, the illumination device 110, and the imaging device 120 are integrally configured,
for example. The integral configuration means that the playback device 100, the lighting device
11-04-2019
7
110, and the imaging device 120 are physically and integrally configured, and a control unit
common to the playback device 100, the lighting device 110, and the imaging device 120.
Meaning controlled by at least one of the following.
[0026]
FIG. 3 shows an example of the configuration of the playback device 100 and the like. The
playback device 100 includes, for example, a control unit 101, a communication unit 102, an
audio processing unit 103, an amplifier 104, and a speaker 105. The communication unit 102,
the audio processing unit 103, and the amplifier 104 are connected to the control unit 101. The
communication unit 102 and the amplifier 104 are connected to the audio processing unit 103.
The speaker 105 is connected to the amplifier 104. For example, the audio processing unit 103,
the amplifier 104, and the speaker 105 constitute a content reproduction unit. Although one
amplifier 104 and one speaker 105 are illustrated in FIG. 3, in actuality, the configuration
corresponds to the number of speakers (eight speakers SP) provided in the housing 10.
[0027]
The control unit 101 is configured of, for example, a CPU (Central Processing Unit), and controls
each unit of the playback device 100. For example, the setting value of the parameter in the
process of the audio processing unit 103 is appropriately changed to change the reproduction
mode of the audio content.
[0028]
The control unit 101 further controls the lighting device 110 and the imaging device 120. The
control unit 101 performs control for changing the brightness of the lighting device 110, for
example. The control unit 101 analyzes the captured image supplied from the imaging device
120, and determines whether a person (user) is in the bed. For example, an image in the vicinity
of the bed when the user goes to bed is captured in advance, and the captured image is stored in
a memory (not shown) as a pattern. Several patterns may be held according to the posture of the
user at bedtime. The control unit 101 performs pattern matching processing to determine
whether a pattern is included in the captured image supplied from the imaging device 120. When
the captured image includes a pattern, the control unit 101 determines that the user is in the
bed.
11-04-2019
8
[0029]
The method of determining whether or not the user is in the bed is not limited to the pattern
matching process. For example, the vicinity of the position where the pillow is placed on the bed
may be imaged to determine whether the skin color component is included in the imaged image.
The control unit 101 determines that the user is in bed when a skin color component is included
in the captured image. Of course, other known methods may be applied to determine if the user
is in bed. When it is determined that the brightness of the lighting apparatus 110 is smaller than
a predetermined brightness and the user is in the bed, the control unit 101 performs control to
change the reproduction mode of the audio content.
[0030]
The communication unit 102 receives audio content supplied from the home server 200 via the
network. Audio content received by the communication unit 102 is supplied to the audio
processing unit 103. Furthermore, the communication unit 102 receives a control signal
transmitted from the portable terminal 300. The control signal is, for example, a control signal
for adjusting the brightness of the illumination or a control signal for changing the reproduction
mode of the audio content.
[0031]
The audio processing unit 103 includes, for example, a DSP (Digital Signal Processor), and
performs various signal processing on audio content input to the audio processing unit 103. For
example, audio content received by the communication unit 102 is input to the audio processing
unit 103. The audio processing unit 103 performs, for example, FFT (Fast Fourier Transform)
processing, digital filtering processing, deinterleave processing, decoding processing, level
control processing, and digital signals subjected to these processing on input audio content. It
performs DAC (Digital to Analog Converter) processing etc. to convert into an analog signal.
[0032]
11-04-2019
9
The amplifier 104 amplifies the audio content processed by the audio processing unit 103 at a
predetermined amplification factor. The amplifier 104 may be configured by a digital amplifier.
Audio content amplified by the amplifier 104 is reproduced from the speaker 105.
[0033]
The lighting device 110 includes, for example, a light emitting unit 111 and a light emission
control unit 112. The light emitting unit 111 includes, for example, a light emitting diode (LED)
and a night light. The light emission control unit 112 operates based on the control of the control
unit 101, and controls switching of the brightness of the LED and the lighting and extinguishing
of the night light.
[0034]
The light emission control unit 112 adjusts the brightness of the LED, for example, by controlling
a direct current flowing to the LED. The brightness of the LED may be adjusted by turning on or
off the current flowing to the LED with a constant frequency and controlling the ratio of the on
period. The functions of the light emission control unit 112 may be incorporated in the control
unit 101. The brightness of the light emitting unit 111 is defined, for example, in units of lumens
(lm). The brightness of the light emitting unit 111 may be defined by other known contents.
[0035]
For example, the light emitting unit 111 can take any of a full light state, a light off state, a state
in which only a night light is turned on, and a light control state. In the all-light state, the LED is
lit at a brightness of 100% (%). In the extinguished state, both the LED and the night light are
extinguished. The dimming state is a state in which the brightness of the LED can be varied. For
example, the brightness of the LED can be changed stepwise in 10% steps. When only the night
light is on, the LED is off. Although details will be described later, any state can be set using the
portable terminal 300.
[0036]
11-04-2019
10
In addition, the light emission part 111 is not restricted to LED, A fluorescent lamp etc. may be
sufficient. The light emission control unit 112 may be configured to include an inverter circuit
for controlling the brightness and the like of the fluorescent lamp.
[0037]
The imaging device 120 includes, for example, an imaging unit 121 and an image processing unit
122. The imaging unit 121 may be, for example, a lens for imaging an object, an imaging element
including a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS),
a mechanism for driving the imaging element to a predetermined position or a mechanism for
adjusting an aperture, and focus , Zoom adjustment mechanism, camera shake correction
mechanism, and the like. The control of the lens, the imaging device, and each mechanism is
performed by the control unit 101, for example. The frame rate of the imaging device 120 is, for
example, 60 f / s (frame per second).
[0038]
The image processing unit 122 includes, for example, an analog signal processing unit, an A / D
(Analog to Digital) conversion unit, and a digital signal processing unit. The analog signal
processing unit performs CDS (Correlated Double Sampling) processing on an analog image
signal obtained by the photoelectric conversion function of the imaging device to make the S / N
ratio (Signal to Noise Ratio) better, and AGC (Automatic Gain) Control) to control the gain. An
analog image signal subjected to analog signal processing is converted into a digital image signal
by an A / D converter. A digital image signal is supplied to the digital signal processor. The digital
signal processing unit subjects the digital image signal to camera signal processing such as
demosaicing processing and AF (Auto Focus), AE (Auto Exposure), AWB (Auto White Balance),
and the like. The image signal subjected to the processing by the image processing unit 122 is
supplied to the control unit 101.
[0039]
“One Example of Operation of Reproduction Device Etc.” An example of the operation of the
reproduction device 100 will be described. Audio content transmitted from the home server 200
is received by the communication unit 102. The audio content to be received is supplied to the
audio processing unit 103. The audio processing unit 103 performs predetermined processing
11-04-2019
11
on the audio content, and the audio content subjected to the processing is supplied to the
amplifier 104. In addition, the example of a predetermined | prescribed process is as having
mentioned above. The audio content that has been processed by the audio processing unit 103 is
amplified by the amplifier 104 and reproduced from the speaker 105.
[0040]
The reproduction mode of the audio content is changed using the portable terminal 300. For
example, the reproduction volume and frequency characteristics of the audio content are
changed. A control signal corresponding to an operation using portable terminal 300 is
generated. The generated control signal is transmitted from the portable terminal 300. The
control signal to be transmitted is received by the communication unit 102 of the playback
device 100. A control signal to be received is supplied from the communication unit 102 to the
control unit 101. The control unit 101 changes the setting value of the audio processing unit
103 according to the supplied control signal, and changes the reproduction volume and
frequency characteristic of the audio content.
[0041]
Next, an example of the operation of the lighting device 110 will be described. Under the control
of the light emission control unit 112, the light emitting unit 111 emits light with a
predetermined brightness. The light emission control unit 112 operates in accordance with
control by the control unit 101. The case where the light emitting unit 111 is an LED will be
described. A control signal for causing the light emitting unit 111 to emit light at a
predetermined brightness is supplied from the control unit 101 to the light emission control unit
112. The light emission control unit 112 controls the value of the DC current of the LED based
on the control signal, and controls the LED so as to have the brightness indicated by the control
signal. When the control signal for lighting the all-night light is supplied, the light emission
control unit 112 performs control to turn off the LED and light the all-night light. In addition, the
change of the brightness of the light emission part 111 is changed using the portable terminal
300, for example.
[0042]
Next, an example of the operation of the imaging device 120 will be described. The imaging unit
11-04-2019
12
121 of the imaging device 120 can capture an image in all directions of 360 degrees, for
example. A range (referred to as an imaging range as appropriate) captured by the imaging unit
121 can be set by the user. For example, a range including the position where the bed is installed
indoors is set as the imaging range.
[0043]
An image signal that is a captured image captured by the imaging unit 121 is supplied to the
image processing unit 122. Image processing is performed on the image signal by the image
processing unit 122, and the image signal subjected to the image processing is supplied to the
control unit 101. An example of image processing is as described above.
[0044]
The control unit 101 compares the above-described pattern with the image signal, and
determines whether or not a user who is a person is present in the bed. The process of
comparing the pattern and the image signal is performed, for example, for each frame. In order
to reduce the load on the control unit 101, processing may be performed to reduce the number
of frames and compare the pattern with the image signal. When a pattern is included in the
image signal, the control unit 101 detects a person in the bed and determines that the user is in
the bed. The image processing unit 122 may perform processing for determining whether or not
the user is in the bed.
[0045]
An example of the operation of each device in the process of automatically controlling the
playback volume of the audio content being played (referred to as appropriate as an automatic
volume control process) will be described.
[0046]
A process of reproducing audio content is performed by the reproduction device 100, and the
audio content is reproduced from the speaker 105.
11-04-2019
13
A range including the position of the bed is imaged by the imaging device 120, and the image
processing unit 122 performs processing on an image signal obtained by imaging. The image
signal subjected to the processing is supplied from the image processing unit 122 to the control
unit 101.
[0047]
During reproduction of the audio content, an operation to make the brightness of the light
emitting unit 111 of the lighting device 110 smaller than a predetermined brightness is
performed using the portable terminal 300. For example, an operation to turn off the light
emitting unit 111 is performed. A control signal for turning off the light emitting unit 111 is
generated according to the operation, and the generated control signal is transmitted from the
portable terminal 300. The control signal is received by the communication unit 102, and the
control signal is supplied to the control unit 101.
[0048]
The control unit 101 analyzes the image signal supplied from the image processing unit 122, and
determines whether a person (user) is present in the bed. When the image signal includes a
pattern, the control unit 101 determines that the user is in the bed.
[0049]
Since the instruction to turn off the light emitting unit 111 is issued and the user is in the bed,
the control unit 101 determines that the user goes to bed. Then, the control unit 101 changes
the reproduction mode of the audio content. For example, the control unit 101 controls the audio
processing unit 103 to mute the reproduction volume of the audio content being reproduced.
[0050]
The control unit 101 controls the light emission control unit 112 according to a control signal
for turning off the light emitting unit 111. The light emission control unit 112 operates based on
the control of the control unit 101. For example, when the light emission control unit 112
11-04-2019
14
controls the value of the current flowing to the LED, the light emitting unit 11 is turned off. The
light emitting unit 111 is turned off, and the reproduction volume of the audio content is
automatically muted. The user can go to bed in a quiet environment without performing an
operation to stop the reproduction of the audio content.
[0051]
“Example of Configuration of Home Server” FIG. 4 shows an example of the configuration of
the home server 200. The home server 200 includes, for example, a control unit 201, a database
202, and a communication unit 203. The control unit 201 includes, for example, a CPU, and
controls each unit of the home server 200. As the process executed by the control unit 201, a
process of reading out predetermined audio content from the database 202 and a process of
modulating audio content are exemplified.
[0052]
The database 202 comprises, for example, a large capacity hard disk drive. The database 202
stores a plurality of audio contents. For example, audio content ripped from a CD (Compact Disk)
may be newly added to the database 202.
[0053]
The communication unit 203 communicates with, for example, the communication unit 102 of
the playback device 100. Furthermore, the communication unit 203 receives a control signal
transmitted from the portable terminal 300. The control signal transmitted from the portable
terminal 300 is, for example, a control signal for selecting audio content to be reproduced.
[0054]
“One Example of Operation of Home Server” An example of the operation of the home server
200 will be described. For example, an operation of selecting audio content to be reproduced is
performed on the portable terminal 300. A control signal generated in response to the operation
is transmitted from the portable terminal 300. The control signal is received by the
11-04-2019
15
communication unit 203. A control signal is supplied from the communication unit 203 to the
control unit 201. The control unit 201 reads out the audio content indicated by the control signal
from the database 202.
[0055]
The control unit 201 subjects the audio content read out from the database 202 to processing
such as modulation processing. The audio content that has been subjected to modulation
processing and the like by the control unit 201 is transmitted from the communication unit 203
to the playback apparatus 100. The audio content is received by the communication unit 102,
and the audio content is reproduced by the reproduction device 100.
[0056]
A list of audio content stored in the database 202 may be generated by the control unit 201, and
the list may be transmitted to the portable terminal 300. The list may be displayed on the display
unit of the portable terminal 300. A plurality of audio contents and a playlist defining the order
of reproduction of the audio contents may be transmitted from the portable terminal 300 to the
home server 200. The control unit 201 may read out and reproduce the audio content indicated
by the playlist in the order indicated by the playlist.
[0057]
“One Example of Configuration of Mobile Terminal” The mobile terminal 300 includes, for
example, a control unit 301, a display unit 302a, a memory 303, a communication unit 304, an
audio processing unit 305, an amplifier 306, and a speaker 307. The display unit 302a is
configured as a touch panel 302b that can operate the display unit 302a.
[0058]
The control unit 301 includes, for example, a CPU, and controls each unit of the mobile terminal
300. The control unit 301 generates a control signal, for example, in response to an operation on
the touch panel 302b. A control signal generated by the control unit 301 is transmitted to the
11-04-2019
16
reproduction apparatus 100, the home server 200, and the like.
[0059]
The display unit 302 a includes a display panel such as an LCD (Liquid Crystal Display) or an

[0066]
“One Example of Operation of Mobile Terminal” An example of the operation of the mobile
terminal 300 will be described. The portable terminal 300 can be used to control a plurality of
electronic devices. For example, a specific application published on the network is downloaded
via the communication unit 304. By executing the downloaded application, an operation screen
for operating a plurality of electronic devices can be displayed on the display portion 302 a.
11-04-2019
18
[0067]
A predetermined operation is performed on touch panel 302b. An operation signal
corresponding to the operation is generated, and the operation signal is supplied from the touch
panel 302 b to the control unit 301. The control unit 301 generates a control signal
corresponding to the operation signal. The control unit 301 modulates the control signal
according to a predetermined method, and supplies the modulated control signal to the
communication unit 304. A control signal is transmitted from the communication unit 304.
[0068]
In the header of the control signal transmitted from the portable terminal 300, for example, an ID
(Identification) assigned to each electronic device is described. Each electronic device that
receives the control signal can determine whether the control signal for itself is present or not by
analyzing the ID described in the header. Furthermore, the control unit 101 of the playback
apparatus 100 can identify which electronic device is the control signal for controlling by
analyzing the ID described in the header.
[0069]
“Display Example of Operation Screen” An example of the operation screen displayed on the
display unit 302 a of the mobile terminal 300 will be described. FIG. 6 is an example of an
operation screen for selecting a device to be controlled (hereinafter, this operation screen is
appropriately referred to as a menu screen). For example, an icon 31a for performing an
operation on the lighting device 110, an icon 31b for performing an operation on the playback
device 100, an icon 31c for performing setting for the imaging device 120, and an operation for
the air conditioner in the display unit 302a. An icon 31d for performing an operation, an icon
31e for performing an operation on the television apparatus, and an icon 31f for operating an
Internet radio apparatus that is transmitted and received via the Internet are displayed.
[0070]
When one of the icons is touched, the operation screen changes to an operation screen for
11-04-2019
19
controlling the electronic device indicated by the icon. FIG. 7 shows an example of the operation
screen displayed when, for example, an operation to touch the icon 31a is performed. The icon
31a indicates illumination as a device to be controlled. Therefore, when the icon 31a is touched,
an operation screen for controlling the lighting device 110 is displayed.
[0071]
A plurality of icons are displayed on the display unit 302 a as an operation screen for controlling
the lighting device 110. As a plurality of icons, an icon 32a for displaying a menu screen, an icon
32b for putting the light emitting part 111 in a full light state, an icon 32c for putting a light
emitting part 111 in a light control state, and a night light An icon 32d for the purpose of turning
on the light emitting unit 11 and an icon 32e for turning off the light emitting unit 11 are
illustrated. Furthermore, an icon 32f and an icon 32g for adjusting the brightness of the light
emitting unit 111 in stages are displayed on the display unit 302a. When the icon 32f is touched,
the light emitting unit 111 becomes dark. When the icon 32g is touched, the light emitting unit
111 becomes bright.
[0072]
FIG. 8 shows an example of the operation screen displayed when an operation of touching the
icon 31b on the menu screen is performed. The icon 31 b indicates music as a control target.
Therefore, when the icon 31b is touched, an operation screen for controlling reproduction of
audio content is displayed.
[0073]
A plurality of icons are displayed on the display unit 302a as an operation screen for controlling
playback of audio content. As a plurality of icons, an icon 33a for displaying a menu screen, a list
33b of audio content, an icon 33c for instructing reproduction of the audio content, and the next
audio content of the audio content being reproduced Icon 33d, an icon 33e for playing back the
audio content of the previous audio content during playback, an icon 33f for increasing the
playback volume (referred to as volume etc.) of the audio content, an audio content And the icon
33g for reducing the playback volume of the.
11-04-2019
20
[0074]
The list 33 b is a list of audio content stored in the home server 200. It may be a list of audio
contents stored in the memory 303 of the portable terminal 300. The list 33 b is transmitted, for
example, from the home server 200 to the portable terminal 300. In the list 33b, for example, the
names of six songs (AAA, BBB... FFF) are displayed. When the list 33b is moved upward or
downward toward the drawing (also referred to as a drag operation), the list 33b is scrolled and
the other song names are displayed.
[0075]
By touching any song name in the list 33b, the audio content of the song name is selected. Then,
when the icon 33 c is touched, a control signal including the identification ID of the audio
content and the reproduction instruction is transmitted to the home server 200. In the home
server 200, audio content corresponding to the identification ID is read, and the audio content is
transmitted to the reproduction device 100. The audio content is reproduced in the reproduction
device 100.
[0076]
Note that, in response to an operation (also referred to as a double-tap operation) in which the
song title is continuously touched twice, audio content corresponding to the song title may be
reproduced. Furthermore, instead of the operation of selecting individual song titles, a playlist
may be selected. The audio content may be read from the home server 200 according to the
playlist, and the audio content may be played back continuously according to the playlist.
[0077]
In addition to this, for example, the reproduction volume of the audio content can be changed by
an operation of touching the icon 33 f or the icon 33 g. The portable terminal 300 may be used
to designate other reproduction devices other than the reproduction device 100.
[0078]
11-04-2019
21
When an operation of touching the icon 31 c on the menu screen is performed, a screen for
setting a range to be imaged by the imaging device 120 is displayed. For example, a screen for
designating a corner of the center of a room or a corner of a room is displayed. The user specifies
the position including the position where the bed is installed.
[0079]
The range to be imaged by the imaging device 120 may be set by another method. For example,
the imaging function of the portable terminal 300 images a range including the position where
the bed is installed. A captured image is sent to the communication unit 102. The control unit
101 appropriately switches the imaging range of the imaging unit 121, and compares the
captured image obtained by imaging with the captured image transmitted from the portable
terminal 300. As a result of comparison, the range in which the captured images are most similar
to each other may be set as an imaging range to be imaged by the imaging unit 121.
Furthermore, the imaging range is set by transmitting a captured image of each predetermined
range captured by the imaging device 120 to the portable terminal 300 and selecting a captured
image of a position including the bed among the captured images. It may be done.
[0080]
The imaging device 120 is configured as a device capable of imaging in all directions, and since
the imaging range can be set, only the range including the position of the bedding such as a bed
can be imaged. Furthermore, since the imaging device 120 can image in all directions, the user
can freely determine the position at which the bed is to be installed. Since the range including the
position of the bed can be reliably imaged, it is not necessary to provide the bed with a sensor or
the like for detecting the user.
[0081]
[An example of flow of processing] Drawing 9 is a flow chart which shows an example of a flow
of volume automatic control processing. In step S1, a process of reproducing audio content is
performed. For example, an operation of selecting audio content to be reproduced and selecting
the reproduction apparatus 100 as a reproduction device is performed using the portable
11-04-2019
22
terminal 300. Then, the home server 200 is instructed to reproduce the audio content.
[0082]
In the home server 200, the audio content selected by the portable terminal 300 is read out.
Audio content is transmitted from the home server 200 to the playback device 100. Audio
content is received by the communication unit 102. The audio content to be received is supplied
to the audio processing unit 103. The audio content processed by the audio processing unit 103
is amplified by the amplifier 104, and the amplified audio content is reproduced from the
speaker 105. Then, the process proceeds to step S2.
[0083]
In step S2, for example, the control unit 101 determines whether or not there is a control request
to turn off the light emitting unit 111 of the lighting device 110. For example, when an operation
is performed to touch the icon 32 e on the operation screen illustrated in FIG. 7, a control signal
including an ID indicating the lighting device 110 as a control target and a predetermined bit
string for turning off is transmitted from the portable terminal 300 Ru. The control unit 101 can
determine whether there is a control request to turn off the light emitting unit 111 by
monitoring the presence or absence of the control signal. If there is no control request to turn off
the light emitting unit 111, the process returns to step S2. Then, the determination process of
step S2 is repeated.
[0084]
If there is a control request to turn off the light emitting unit 111, the process proceeds to step
S3. In step S3, the control unit 101 analyzes the image signal supplied from the image processing
unit 122. The image signal is a captured image obtained by capturing an image of a position
including the bed by the imaging unit 121. Then, the process proceeds to step S4.
[0085]
In step S4, the control unit 101 determines whether the user is in the bed. For example, the
11-04-2019
23
control unit 101 holds, as a pattern, an image in a state in which the user has fallen on the bed,
and determines that the user is in the bed when this pattern is included in the image signal. If it
is determined that the user is not in the bed, the process proceeds to step S6.
[0086]
In step S6, the control unit 101 controls the light emission control unit 112 according to the
control signal for turning off the illumination. The light emission control unit 112 operates based
on control by the control unit 101, and turns off the light emitting unit 111. At this time, the
reproduction mode of the audio content being reproduced is not changed. That is, since the user
is not in bed, the user determines to listen to audio content in the dark. Therefore, the
reproduction mode of the audio content is not changed. Then, the process ends.
[0087]
If it is determined in step S4 that the user is in bed, the process proceeds to step S5. In step S5,
the playback volume of the audio content being played back is muted. That is, the control unit
101 determines that the user goes to bed because the illumination is turned off and the user is in
the bed. The control unit 101 controls the audio processing unit 103 to mute the reproduction
volume of the audio content being reproduced. Then, the process proceeds to step S6, and the
light emitting unit 111 is turned off. Thus, when the user goes to bed, the playback volume of the
audio content being played back can be automatically muted.
[0088]
<2. Modifications> Although the plurality of embodiments of the present disclosure have
been described above, the present disclosure is not limited to the above-described embodiments,
and various modifications are possible.
[0089]
The appearance of the playback device or the like can be changed as appropriate. For example,
the shape shown in FIG. 10 may be used. The playback device 400, the lighting device 500, and
11-04-2019
24
the imaging device 600 are erected toward the room from the ceiling 40. The playback device
400 and the lighting device 500 are integrally configured. In the vicinity of the reproduction
device 400 and the lighting device 500, the imaging device 600 is provided upright.
[0090]
The playback device 400 includes a receiver 401, a speaker 402, and a speaker cover 403. In
FIG. 10, the speaker cover 403 is indicated by a dotted line in order to distinguish it from the
light transmitting housing 502 described later. The receiver 401 has functions of a
communication unit 102, an audio processing unit 103, and an amplifier 104. That is, audio
content transmitted from a home server or the like is received by the receiver 401, and the
receiver 401 performs predetermined signal processing on the audio content. The processed
audio content is amplified. Audio content is played back from the speaker 402.
[0091]
The lighting device 500 includes a light bulb 501 and a light transmitting housing 502. The
housing 502 is, for example, shaped to be wider in the direction toward the room. The light bulb
501 is housed inside the housing 502. Furthermore, the receiver 401 and the speaker 402 are
housed inside the housing 502.
[0092]
The imaging device 600 is installed at a position close to the reproduction device 400 or the like.
The imaging device 600 includes an imaging unit 601 and a housing 602 provided upright from
the ceiling 40. The imaging unit 601 is attached to the tip of the housing 602. The imaging unit
601 can, for example, capture images in all directions. The range to be imaged by the imaging
device 600 may be set. A control unit or the like that controls each of these devices is housed in
the ceiling 40. Wireless communication is performed between the control unit and the receiver
401. Thus, the appearance of the playback device or the like can be changed as appropriate.
[0093]
The embodiments described above can be further modified as follows.
11-04-2019
25
[0094]
In the embodiment described above, the control signal for turning off the lighting device 110 is
exemplified as a control signal for making the brightness of the lighting device 110 smaller than
a predetermined brightness, but the control signal is not limited to this.
For example, the control signal to make the brightness of the lighting device 110 smaller than a
predetermined brightness may be a control signal to turn on the night light. Furthermore, it may
be a control signal for making the brightness of the light emitting unit 111 smaller than the
threshold when the light emitting unit 111 of the lighting device 110 is in the light control state.
[0095]
In the embodiment described above, the device constituting the system 1 has been described as a
device corresponding to DLNA, but the present invention is not limited to this. For example, audio
content may be transmitted from the home server 200 to the playback device 100 by Bluetooth
(registered trademark) or Wi-Fi (registered trademark). Furthermore, audio content may be
transmitted from the portable terminal 300 to the playback device 100.
[0096]
When muting the reproduction volume of the audio content, the reproduction volume may be
gradually decreased. Furthermore, audio content suitable for going to bed may be played back.
Furthermore, not only the reproduction volume but also the reproduction mode of the audio
content may be changed and the volume may be gradually reduced so that the frequency
characteristic is suitable for going to bed.
[0097]
The control unit 101 may change the timing at which the imaging device 120 operates. For
example, when audio content is played back, power may be supplied to the imaging device 120,
and the imaging device 120 may be activated. Furthermore, when the brightness of the lighting
11-04-2019
26
device 110 is made smaller than a predetermined brightness, the control unit 101 performs
processing for analyzing the captured image, and in other cases, the captured image is discarded.
It is also good. Since it is not always necessary to activate the imaging device 120, power saving
can be realized, and the load on the control unit 101 can be reduced.
[0098]
The imaging device 120 may be an infrared camera capable of imaging even in the dark. For
example, after the illumination is turned off, imaging by the imaging device 120 may be
performed.
[0099]
The present disclosure can be realized by an apparatus, a method, a program, a recording
medium in which the program is recorded, and the like. In addition, the structure and process in
embodiment and a modification can be suitably changed and combined in the range which a
technical contradiction does not arise. The illustrated processing may be performed in parallel.
For example, the process of determining the presence or absence of the control request to turn
off the illumination and the process of analyzing the captured image and determining whether
the user is in the bed may be performed in parallel.
[0100]
Furthermore, the present disclosure can be applied to a so-called cloud system in which the
illustrated process is distributed and processed by a plurality of devices. For example, the present
disclosure may be realized as a system that performs all the illustrated processes and an
apparatus that performs some of the processes.
[0101]
The present disclosure can also have the following configurations. (1) A content reproduction
unit that reproduces content, and a control unit that controls the reproduction mode of the
content And, when a person is detected in a predetermined range, the control unit changes the
11-04-2019
