[0041]
In the present embodiment according to the above configuration, when mobile phone 1 is in the
call reception standby state, first control unit 20 performs steps S1 to S8 in the flowchart of FIG.
7 based on the program stored in system ROM 203. Execute the process That is, first, it is
determined whether a download instruction has been detected (step S1). Here, the download
instruction is not only when the user operates the network connection key 84 to manually issue
the download instruction, but also by registering the download start time and the address (URL)
in the schedule data in advance. For example, it means that the start of the data communication
mode is instructed at midnight.
[0042]
If the download instruction is detected, the reception signal processing unit 18 is operated (step
S2). Then, it is connected to the network through the reception signal processing unit 18, and the
compressed multimedia file (illustration, still image, moving image (including aspect of 16: 9),
melody, audio) received by this is stored as download data It stores in the area 244 (step S3).
Further, upon completion of the download of the multimedia file, the reception end processing is
executed to stop the reception signal processing unit 18 (step S4).
[0043]
Furthermore, it is determined whether the multimedia file stored in the download data storage
area 244 in step S3 described above is a video content (step S5). If the content is video content, it
is determined whether the video content is a content for streaming reproduction (a pseudo
streaming reproduction service which is reproduced once after downloading and then deleted
(step S6)). When the video content is a content for streaming reproduction, an icon to the effect
that the content for streaming reproduction is stored in the download data storage area 244 is
displayed on the display unit 6, and a state of waiting for a reproduction instruction operation is
10-05-2019
13
entered. (Step S7). However, if it is not the video content as a result of the determination in step
S5, and if it is not the content for streaming reproduction but the content without reproduction
restriction as a result of the determination in step S6, the display unit 6 displays it in step S7. A
predetermined icon different from the displayed icon is displayed (step S8).
[0044]
On the other hand, when the download instruction is not detected as a result of the
determination in step S1, the second control unit 22 determines the lid 2 and the main body in
steps S9 to S16 based on the program stored in the program ROM 23. The switching process
according to the open / close state detection with the unit 3 is executed. That is, it is determined
whether or not the magnetism of the first speaker 5 is detected by the first magnetism detection
unit 28 (step S9). At this time, as shown in FIGS. 2 (a) and 2 (b), the mobile phone 1 is in a folded
state in which the lid 2 faces the display 6 and the key input unit 8 (folded state when carrying)
The second magnetic detection unit 29 can detect the magnetism of the magnetic circuit of the
first speaker 5. Therefore, the determination in step S9 is YES, and in this case, the process
returns without shifting to the camera mode process (step S16). Therefore, as described above,
when the display unit 6 and the key input unit 8 are folded so as to face each other, the first side
switch 9 functions as a shutter key because there is no transition to the camera mode. I have
nothing to do.
[0045]
However, as shown in FIG. 3, when the lid 2 is opened and the lid 2 is at a predetermined angle
or more with respect to the main body 3, the first magnetic detection unit 28 is separated from
the first speaker 5, It will be in the state of non-magnetic detection (Step S9; NO). In this case,
first, the display driver 61 is activated (step S10), and status display such as displaying a standby
screen on the display unit 6 is performed (step S11). Furthermore, it is determined whether the
second magnetism detection unit 29 has detected magnetism (step S12). If the determination in
step S12 is YES and the determination in step S9 described above is NO, in the state of FIG. 2A,
the cover 2 is opened and rotated about the first hinge 100 (step S9). YES), the cover 2 is rotated
about the second hinge 12 and the cover 2 is closed again (step S12; YES). Therefore, as shown
in FIG. 4, the lid 2 is folded on the inner surface of the main body 3 on which the ten keys 810
and the like are provided, with the display 6 side as an upper surface.
[0046]
10-05-2019
14
Then, in the state of FIG. 4, the key input unit 8 (cross key 81, enter key 82, address book key
83, network connection key 84, movie playback key 85, mail key 86, off hook key 87, clear The
operation on the key 88, the on-hook key 89, and the ten-key pad 810 is disabled, and the
operation on the second side switch 4 is maintained valid (step S13). That is, in order to prevent
a malfunction, the operation of the key input unit 8 is completely canceled, while the operation of
the second side switch 4 is enabled. Subsequently, the camera module including the imaging
device 171, the DSP 172, and the compression / decompression processing unit 25 is activated
(step S14), the subject image is displayed on the display unit 6 (step S15), and camera mode
processing is started (step S16). As described above, since the effective pixel area of the image
sensor in the present embodiment is fixed at the aspect ratio of 4: 3, the subject image is
displayed on the display unit 6 at the aspect ratio of 4: 3 in step S15. Be done.
[0047]
On the other hand, as a result of the judgment in step S12, when the magnetism of the first
speaker 5 is not detected by the second magnetism detection unit 29, as shown in FIG. is there.
In this case, the display unit 6 faces the opposite side to the surface on which the imaging lens
17 of the main unit 3 is located, and imaging by the user is assumed. Therefore, also in this case,
the camera module including the imaging device 171, the DSP 172, and the compression /
decompression processing unit 25 is activated (step S14), the subject image is displayed on the
display unit 6 (step S15), and the camera mode processing is started. (Step S16).
[0048]
Thereafter, the process proceeds to step S17 of FIG. 8 to determine whether the movie playback
mode is selected (step S17). If the movie playback mode is not selected, the process proceeds to
another mode processing. When the movie reproduction mode is selected, the display driver 61
is set to the widescreen display aligned with the vertical direction (step S18), and the process
proceeds to the movie reproduction mode processing (step S19).
[0049]
FIG. 9 is a flowchart showing details of the camera mode process (step S16). In this flowchart,
10-05-2019
15
S31 to S42 indicate still image shooting processing procedures, and S43 to S52 indicate movie
shooting processing procedures. That is, first, it is determined whether the movie mode selection
by the key input unit 8 or the second side switch 4 is detected (step S31). If movie mode
selection is not detected, it is determined whether or not setting change processing by the key
input unit 8 or the second side switch 4 is detected (step S32). If the setting change process is
not detected, the process proceeds to step S34. If the setting change process is detected, the
setting is changed according to the operation, and the icon displayed on the display unit 6 is
changed. The setting change is reflected on the monitor by the like (step S13). Further, as
described above, the subject image is displayed on the monitor with the aspect ratio of 4: 3 (step
S34).
[0050]
That is, in the state of the camera mode processing, as shown in FIG. 12, in the 2.7 inch (240 ×
428 dots) display unit 6 capable of displaying an image with an aspect ratio of 16: 9, the aspect
ratio of 4: 3 An area (240 × 320 dots) is a monitor display area 601 for displaying an object
image. Therefore, using the display areas remaining on both sides of the monitor display area
601 effectively, the self-timer icon 602, the shooting mode icon 603, the white balance icon (in
the display example, outdoor light) 604, the Ev (exposure) gauge 605, the shooting mode Display
(in the display example, resolution equivalent to UXGA, 1600 × 1200 (dots)) 606, zoom (optical
zoom 3 ×, digital zoom 16 × 3 × 16, can be enlarged to 48 ×) 607, reception status icon 608,
remaining battery power An icon 609, a movie shooting mode switching icon 610, and the like
can be displayed. Therefore, in step S33, the display etc. of the icons 601 to 610 are changed in
accordance with the operation, and in step S34, the subject image is displayed on the monitor
display area 601.
[0051]
Therefore, by adopting the display unit 6 capable of displaying an image with an aspect ratio of
16: 9, the icons and the like 601 to 610 do not overlap the subject image in the monitor display
area 601 at the time of shooting. Therefore, the angle of view to be photographed can be
displayed on the liquid crystal without any trouble, and the contents of the photographing setting
and the respective states of the mobile phone can be displayed in an easy-to-see manner.

Then, in step S35 following step S34, it is determined whether or not the operation of the first
side switch 9 functioning as a shutter key is detected in the camera mode (step S35). The image
data is fixed to the image data at the time of operation (step S36). Subsequently, it is determined
whether or not the operation of the first side switch 9 is detected again (step S37), and if it is not
detected, it is determined whether or not the cancel operation is detected, and steps S36 → S37
→ S41 → Wait while repeating the loop of S36.
[0053]
If a cancel operation is detected during this time (step S41; YES), the display buffer 62 is cleared
(step S42), and the process from step S34 is executed again. If the operation of the first side
switch 9 is detected again (step S41; YES), the image data fixed in the display buffer 62 is
compressed (step S38), and the compressed image data is processed. The date is stored as a file
name in the image storage area 243 of the RAM 24 (step S39). Further, it is determined whether
or not camera mode omission is detected (step S40), and the process from step S34 is repeated
until it is detected, and when it is detected, the process returns to the start in the flowchart of
FIG.
[0054]
On the other hand, if movie mode selection is detected as a result of the determination in step
S31, it is determined whether or not setting change processing by the key input unit 8 or the
second side switch 4 is detected (step S43). If the setting change process is not detected, the
process proceeds to step S46. If the setting change process is detected, it is determined whether
it is the selection of cinema size shooting (step S44). If cinema size shooting is not selected (with
normal size shooting selected), the setting change is reflected on the monitor by changing the
icon displayed on the display unit 6 or the like (step S53). The subject image is displayed on the
monitor at an aspect ratio of 4: 3 (step S46).
[0055]
That is, in the shooting mode in the movie mode and the normal size, as shown in FIG. 13, as in
the case of the camera mode, 2.7 inches (240 × 428 dots) capable of displaying an image with
an aspect ratio of 16: 9. ) In the display unit 6, a region (240 × 320 dots) having an aspect ratio
10-05-2019
17
of 4: 3 is a monitor display area 601 for displaying an object image. Therefore, the display
elapsed time 611, Ev (exposure) gauge 605, moving image shooting size icons (4 patterns of S,
M, L, CINEMA) 612, zoom using the display areas remaining on both sides of the monitor display
area 601 effectively 607, the reception status icon 608, the battery remaining amount icon 609,
the camera shooting mode switching icon 613 and the like are displayed. Therefore, in step S53,
the display is changed in accordance with the operation.
[0056]
Therefore, by adopting the display unit 6 capable of displaying an image with an aspect ratio of
16: 9, the icons and the like overlap the subject image of the monitor display area 601 as
described above even during normal size shooting in movie mode. I have not. As a result, the
angle of view to be photographed can be displayed on the liquid crystal without any trouble, and
the contents of the photographing setting and the respective states of the mobile phone can be
displayed in an easy-to-see manner.
[0057]
If cinema size shooting is selected as a result of the determination in step S44, the monitor size is
changed to the cinema size (step S45), and the subject image is displayed on the monitor with the
aspect ratio of the cinema size (step S45) S46).
[0058]
At this time, the display unit 6 can display an image with an aspect ratio of 16: 9, but the
effective pixel area of the image sensor in the present embodiment is fixed at an aspect ratio of 4:
3 as described above. The pixel area that can be captured by the image sensor does not
correspond to 16: 9.
For this reason, in the movie mode and in the cinema size shooting state, as shown in FIG. 14, the
moving image display area 615 (FIG. 14) displays the subject image from the 4: 3 effective pixel
area to the area corresponding to 16: 9. The other upper and lower regions are captured as black
images 614 ((30 × 320 dots) × 2). Therefore, as described above, the display elapsed time 611,
the Ev (exposure) gauge 605, the moving image shooting size icon 612, the zoom 607, the
reception status icon 608, and the display areas remaining on both sides of the monitor display
area 601 are effectively used. Not only can the battery remaining amount icon 609, the camera
10-05-2019
18
shooting mode switching icon 613, etc. be displayed, but also the black image 614 can be
effectively used to display the current date and time 616.
[0059]
Next, it is determined whether the operation of the first side switch 9 has been detected (step
S47). If it is detected, the image is sequentially taken into the display buffer 62 (step S48),
compressed (step S49), and the operation of the first side switch 9 is detected again (step S50),
steps S48 and S49. Repeat the process of When the operation of the first side switch 9 is
detected again (step S50; YES), the moving image data generated in the display buffer 62 is
stored in the image storage area 243 of the RAM 24 with the date as the file name ( Step S51).
Further, it is determined whether or not camera mode omission is detected (step S51), and the
process from step S46 is repeated until it is detected, and when it is detected, the process returns
to the start in the flowchart of FIG.
[0060]
FIG. 10 is a flowchart showing details of the movie reproduction mode process (step S26). In this
flowchart, S61 to S63 show the reproduction processing procedure of the downloaded movie file,
and S64 (YES judgment) to S73 show the processing procedure for reproducing the file
photographed by the own device.
[0061]
First, when the movie reproduction mode process is executed, it is determined whether or not the
magnetic detection by the second magnetic detection unit 29 is detected (step S61). Here, when
the determination in step S61 is YES, as described above, the lid 2 is folded on the inner surface
of the main body 3 on which the ten keys 810 and the like are provided with the display 6 side
facing up. It is done. Then, in the movie playback mode, as shown in FIG. 11A, with the display
unit 6 in the horizontal direction, both ends of the mobile phone 1 in the folded state with both
hands LH and RH are removed It is a case of watching a movie while holding it. Then, at the time
of movie reproduction in the state of FIG. 11 (a), the switch 21 is closed because an appropriate
stereo effect is produced by the sound emission from the first speaker 5 and the second speaker
7. The stereo speaker setting is performed to turn on the first speaker 5 and the second speaker
7 (step S62).
10-05-2019

[0062]
When the determination in step S61 is NO, the cover 2 is only opened from the state of FIG. 2A
and rotated about the first hinge 100 (step S9; YES). The mobile phone 1 is in the state shown in
FIG. 1, which is a case where the display unit 6 is in the vertical direction and the user grips the
main unit 3 to watch a movie. However, when the first speaker 5 and the second speaker 7 are
turned on at the time of movie reproduction in the state of FIG. 1, the switch 21 is opened
because the sound is emitted from the upper and lower sides and a sense of discomfort is
generated. A monaural speaker setting is performed to turn on only the speaker 5 (step S63).
[0063]
Next, it is determined whether the movie shot by the user's own terminal (the mobile phone 1) is
selected by the user (step S64). When a movie photographed by the own terminal is selected, the
image storage area 243 is searched (step S65), and the top frame of the movie file stored in the
image storage area 243 is displayed as a thumbnail list on the display unit 6 ( Step S66). At this
time, a movie file shot in 4: 3 size and a movie file shot in 16: 9 (cinema-size shot) are mixedly
stored in the image storage area 243, as shown in FIG. The thumbnails 620 are displayed in
different sizes according to each size as shown in FIG. At this time, with regard to the top frame
of the movie file photographed in the cinema size, the black image 614 is thumbnailed in a
deleted form, and the menu is displayed with the height direction of each displayed thumbnail
620 unified as shown. Do.
[0064]
Further, the state of the menu display shown in FIG. 15 is maintained, and the process waits until
any movie is selected (step S67). This movie file to be played back is selected by vertical click of
the second side switch 4 (rotation), and if any movie is selected, is it a file captured in cinema
size? It is determined whether or not it is (step S68). In the case of a file shot in cinema size, an
image excluding the black images 614 in the upper and lower regions of the movie file is
displayed on the full screen on the display unit 6 (step S69). Therefore, when a movie file shot in
cinema size is selected, the top frame of the movie file is displayed on the entire screen (240 ×
428 dots) on the display unit 6, as shown in FIG.

[0065]
Next, it is judged whether or not a reproduction instruction is detected (step S70), and when the
center of the second side switch 4 is pressed, a reproduction instruction is generated, and if this
is detected, the movie file is expanded Process and reproduce (step S71). At this time, based on
the determination result in step S61 described above, the determination in step S61 is NO, and as
shown in FIG. 11A, the state of viewing the movie with the display unit 6 in the horizontally long
direction In the case of the above, as shown in FIG. 16, the movie photographed in the normal
size is displayed on the full screen of the display unit 6. If the determination in step S61 is YES
and the display unit 6 is in the portrait orientation and the movie is viewed as shown in FIG. 1, as
shown in FIG. The movie photographed in the above is displayed on the central portion of the
display unit 6 together with the upper and lower black images 614. Therefore, in the
reproduction display state of the cinema size movie shown in FIG. 17, as shown, the reception
state icon 608, the battery remaining amount icon 609, and the current date and time 616 are
displayed at the top of the upper and lower blank portions of the display unit 6. The operation
icons 617, 618 and 619 for the movie reproduction key 85, the decision key 82 and the address
book key 83 of the key input unit 8 are displayed at the bottom.
[0066]
On the other hand, if it is determined in step S68 that the selected movie is not a cinema size but
a file captured in a normal size, the top frame is displayed on the full screen (step S75). As a
result, as shown in FIG. 16, the top frame of the normal size movie file is displayed on the entire
screen of the display unit 6.
[0067]
Next, it is judged whether or not a reproduction instruction is detected (step S75), and when the
center of the second side switch 4 is pressed, a reproduction instruction is generated, and if this
is detected, the movie file is expanded Process and reproduce (step S71). At this time, based on
the determination result in step S61 described above, the determination in step S61 is NO, and as
shown in FIG. 11A, the state of viewing the movie with the display unit 6 in the horizontally long
direction In the case of the above, as shown in FIG. 16, the movie photographed at the cinema
size is displayed on the full screen on the display unit 6. Also, if the determination in step S61 is
YES and the display unit 6 is in the portrait orientation as shown in FIG. 1 and the movie is to be
10-05-2019
21
viewed, as shown in FIG. The photographed movie is displayed at the center of the display unit 6.
Accordingly, even in the reproduction display state of the normal size movie shown in FIG. 18,
the reception state icon 608, the battery remaining amount icon 609, the current state at the top
of the upper and lower blank portions of the display area 601 of the display unit 6 The date and
time 616 is displayed, and operation icons 617, 618 and 619 for the movie reproduction key 85,
the enter key 82 and the address book key 83 of the key input unit 8 are displayed at the lower
part.
[0068]
If a movie of cinema size or normal size is reproduced by the above processing, it is judged
whether or not the reproduction of the movie is completed (step S72), and if the reproduction is
completed, the mode of the movie reproduction mode is lost. It is determined whether or not it
has been detected. Then, the process from step S66 is repeated until a mode drop is detected,
and when the mode drop is detected, the process returns to the start of the flowchart shown in
FIG. 7 and shifts to a reception standby state.
[0069]
In this reception standby state, as shown in FIG. 19, when the image taken by the own device is
set as the wallpaper 622, the normal size wallpaper 622 is displayed vertically in the wide size
display portion 6 in the vertical direction. Let Therefore, since the blank parts remain at the top
and bottom of the display unit 6, as shown, the reception status icon 608, the battery remaining
amount icon 609, and the current time 616 are displayed at the top of this blank part. It is also
possible to provide an area 621 for displaying Exif data of the image file used as 622.
