  As shown in FIG. 4A, in the present embodiment, on the display screen in the double video display mode, the bar 6 is, for example, from the center position (position A7) upward to the position A1 and below A13. Controlled to move to position. In the volume increase / decrease table, increase / decrease values of the volume of the first speaker device 11 and the second speaker device 12 corresponding to the position of the bar 6 are set as shown in FIG. In the volume increase / decrease table, when the bar 6 is moved downward from the center position (the first screen region R1 is enlarged), the volume of the first speaker device 11 is increased and the volume of the second speaker device 12 is increased. When the volume is reduced and the bar 6 is moved upward (the second screen region R2 is enlarged), the volume of the second speaker device 12 is increased and the volume of the first speaker device 11 is decreased. ing.

  The CPU 100 controls each part such as the communication module 107, the video decoder 109, and the audio decoder 110 based on input signals from each part such as the touch panel 4, jog dial 7, R button 8, L button 9, microphone 105, and image sensor 10 c. Is output to perform various function modes (call mode, mail mode, Internet mode, television mode, camera mode, etc.).

  In the double video display mode, the CPU 100 simultaneously displays two different video contents acquired by the first TV module 102 and the second TV module 103 on the liquid crystal display panel 2a through the video encoder 109. In this double video display mode, the CPU 100 outputs the audio of the video content in the first screen region R1 from the first speaker device 11 and outputs the audio of the video content in the second screen region R2 from the second speaker device 12. Let Then, when an operation for moving the bar 6 is performed, the CPU 100 changes the ratio of the first screen area R1 and the second screen area R2 accordingly, and in accordance with the volume increase / decrease table based on the position of the bar 6. The volume output from the first speaker device 11 and the second speaker device 12 is changed.

  Hereinafter, volume control in the double video display mode will be described in detail with reference to FIGS. 5 and 6. FIG. 5 is a flowchart showing the volume control operation. FIG. 6 is a diagram showing the state of the display screen and the volume when the sizes of the screen areas R1 and R2 are changed.

  When the user performs an operation for shifting to the double video display mode on the television mode display screen shown in FIG. 2A (S101: YES), the CPU 100 displays two different types as shown in FIG. Video content is simultaneously displayed in the screen areas R1 and R2 (S102). For example, the video content acquired by the first TV module 102 is displayed in the first screen area R1, and the video content acquired by the second TV module 103 is displayed in the second screen area R2. In addition, video content acquired from the outside by the communication module 107 and video content recorded (recorded) in the memory 101 in advance can be displayed simultaneously.

  As shown in FIG. 6A, in the initial state of the double video display mode, the bar 6 is located at the center of the display screen, and the first screen area R1 and the second screen area R2 are of equal size. Yes. Each video content is displayed vertically in each of the screen areas R1 and R2. In each of the screen areas R1 and R2, information related to the video content such as a channel number and a genre name is displayed in an area other than the area where the video content is displayed (hereinafter referred to as “information display area”). The audio of the video content in the first screen region R1 is output from the first speaker device 11, and the audio of the video content in the second screen region R2 is output from the second speaker device 12. The bar 6 can be moved up and down by a predetermined range (A1 to A13 in the figure) by a user operation. For example, the predetermined range may be a range in which the display size of the video content is not reduced when one screen area is reduced by the movement of the bar 6.

  In such a state, when the user wants to mainly view one video content, the user performs an operation to enlarge the screen area on which the video content is displayed. That is, the user touches the bar 6 with a finger or the like, and moves the bar 6 in a direction in which the screen area on which the video content is displayed is expanded.

  During the operation of the double video display mode, the CPU 100 monitors whether or not the bar 6 has moved. When the bar 6 is moved by the user's operation, the CPU 100 determines that the bar 6 has moved (S103: YES), and sets the first screen area R1 and the second screen area R2 according to the position of the bar 6. (S104). Further, the CPU 100 changes the volume of the first speaker device 11 and the second speaker device 12 according to the set value of the volume increase / decrease table based on the position of the bar 6 (S105).

  For example, as shown in FIG. 6B, when the bar 6 is moved downward, the first screen area R1 is enlarged, the information display area is enlarged, and the second screen area R2 is reduced. The information display area becomes smaller. Further, according to the amount of movement of the bar 6, the volume of the video content displayed in the first screen area R1 increases, and the volume of the video content displayed in the second screen area R2 decreases.

  On the other hand, as shown in FIG. 6C, when the bar 6 is moved upward, the second screen area R2 is enlarged, the information display area is enlarged, and the first screen area R1 is reduced. The information display area becomes smaller. Further, according to the amount of movement of the bar 6, the volume of the video content displayed in the first screen area R2 increases, and the volume of the video content displayed in the first screen area R1 decreases.

  Thus, the CPU 100 changes the volume of each video content in accordance with the movement of the bar 6 during the operation of the double video display mode. When the user performs a return operation such as pressing and holding the jog dial 7 (S106: YES), the double video display mode is terminated and the first television mode display screen shown in FIG. Display.

  In addition, in the state where the size of the screen area shown in FIGS. 6B and 6C is changed, the user can further adjust the volume of each of the screen areas R1 and R2. That is, when the user taps the enlarged screen area with a finger or the like, the volume of the video content in the screen area is further increased by a certain amount per tap. In contrast, when the user taps the reduced screen area with a finger or the like, the volume of the video content in the screen area is further reduced by a certain amount per one tap.

  In this case, the CPU 100 determines, based on a signal from the touch panel 4, whether one of the screen areas R1 and R2 has been tapped. If the tapped area is an enlarged screen area, the CPU 100 increases the volume of the video content in the screen area by a certain amount, and if the tapped area is a reduced screen area, the CPU 100 The audio output circuit 111 is controlled to reduce the volume of the video content in the area by a certain amount.

  When the user wants to change the channel, the channel of the first screen region R1 can be switched by rotating the jog dial 7 upward, and the second screen can be switched by rotating the jog dial 7 downward. The channel of the region R2 can be switched.

  As described above, in the present embodiment, when the user wants to mainly view one of the video contents in the double video display mode and performs an operation of expanding the screen area of the video content, the operation is linked. Thus, the volume of the enlarged screen area is increased, and the volume of the reduced screen area is decreased. Therefore, the user does not need to perform an operation of increasing the volume of the screen area and reducing the sound of the reduced screen area after enlarging the main screen area to be viewed. Therefore, the operation by the user can be simplified and the user-friendliness can be improved.

  In the present embodiment, after the volume is changed in accordance with the size change of each screen area, the volume of the screen area can be further adjusted by tapping the desired screen area. Therefore, user convenience can be further improved.

  In the above embodiment, the volume of the reduced screen area is reduced. However, the present invention is not limited to this, and the sound of the reduced screen area may be erased (muted). Good.

  In the above embodiment, the volume of the screen area is increased when the enlarged screen area is tapped, and the volume of the screen area is decreased when the reduced screen area is tapped. Has been. However, the volume adjustment operation is not limited to a tap, and may be an operation of touching a screen area with a finger or the like and tracing up and down or left and right. In this case, the volume can be increased by tracing in one direction, and the volume can be decreased by tracing in the other direction.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and the embodiment of the present invention is also appropriately within the scope of the technical idea shown in the claims. Various modifications are possible. For example, the embodiment of the present invention can be modified as follows.

<Modification 1>
FIG. 7 is a diagram illustrating a display screen and a volume state when the sizes of the screen areas R1 and R2 are changed according to the first modification.

  In the above embodiment, when one screen area is enlarged, the information display area is enlarged, but the display size of the video content is not changed.

  On the other hand, in the configuration of the modified example 1, as shown in FIGS. 2B and 2C, when one of the screen areas is enlarged to some extent, the display direction of the video content is changed to the horizontal direction. It is configured to increase in size. With this configuration, the user can view desired video content in a large display size.

<Modification 2>
In the above embodiment, when one screen area is enlarged, the volume of the enlarged area is increased accordingly. However, particularly in the case of the configuration as in Modification 1, it is not always optimal to increase the volume when the screen area is enlarged depending on the combination of the genres of two video contents displayed at the same time. It is possible.

  For example, when the genre of video content in one screen area is “sports” and the genre of video content in the other screen area is “news”, the screen area on the “news” side is expanded. It is desirable to increase the volume of the screen area on the “news” side, but on the contrary, when the screen area on the “sport” side is enlarged, the sound of the enlarged screen area on the “sport” side is reduced. It is desirable that the volume of the reduced “news” is increased. Because in “Sports”, the video is important, so if the display size is large, the need for audio is lessened, but in “News”, the audio is important, so the display size This is because if it is small, it is desirable to increase the volume only.

  Therefore, in the second modification, a plurality of volume adjustment control patterns are prepared, and the volume is adjusted according to the combination of the genres of the two video contents to be displayed.

  In the configuration of the second modification, the volume increase / decrease table shown in FIG. 8 is stored in the memory 106 instead of the volume increase / decrease table shown in FIG.

  In the volume increase / decrease table of FIG. 8, increase / decrease values of the volume of the first speaker device 11 and the second speaker device 12 in the three control patterns of “control 1”, “control 2”, and “control 3” are set. The control pattern of “control 1” is the same as the set value of the volume increase / decrease table in FIG. In the control pattern of “control 2”, the volume of the first speaker device 11 is reduced regardless of whether the bar 6 moves upward or downward (either the first screen region R1 is enlarged or reduced). The volume of the second speaker device 12 is increased. In the control pattern of “control 3”, the first speaker, regardless of whether the bar 6 moves up or down (either the first screen region R1 is enlarged or reduced) contrary to the “control 2”. The volume of the device 11 is increased, and the volume of the second speaker device 12 is decreased.

  The memory 106 further stores a control pattern setting table shown in FIG. In the control pattern setting table, a control pattern to be applied is set for each combination of video contents displayed in the first screen area R1 and the second screen area R2. For example, in the case of a combination of genres other than “sports”, “control 1” is applied. Also, “control 1” is applied to the combination of genres of “sports”. Further, when the first screen area R1 is a genre of “sports” and the second screen area R2 is a genre other than “sports”, “control 2” is applied, and conversely, the first screen area R1 is “sports”. When the second screen area R2 is a genre of “sports” with a genre other than “”, “control 3” is applied.

  Further, when acquiring video content from the outside via the first TV module 102, the second TV module 103, or the like, the CPU 100 acquires genre information of the video content as follows. For example, when video content is transmitted by terrestrial digital broadcast waves, genre information is arranged in an EIT (Event Information Table) included in the broadcast waves. Therefore, the CPU 100 acquires the genre information of this EIT. In the case of video content streamed from the server or video content downloaded from the server, the CPU 100 acquires genre information of the video content from the server when accessing the server. Furthermore, when video content is sent by terrestrial analog broadcast waves, the broadcast waves themselves do not include genre information. In this case, the CPU 100 accesses a broadcasting station or the like in advance and obtains an EPG (electronic program guide). This EPG includes genre information of a television program (video content). The CPU 100 acquires the genre of the video content from the EPG based on the time when the video content is received and the reception channel.

  Thus, in the configuration of the modification example 2, the volume control similar to that in the above-described embodiment shown in FIG. 6 is performed in the double video display mode. However, in step S105 in the figure, the CPU 100 determines the volume of each video content according to the volume increase / decrease table and the control pattern setting table based on the position of the bar 6 and the genre of the video content displayed in each screen area R1, R2. To change.

  FIG. 10 is a diagram illustrating a display screen and a volume state when the sizes of the screen regions R1 and R2 are changed according to the second modification. FIG. 11A shows an example when the genre of the first screen area R1 is “sports” and the genre of the second screen area R2 is “news”, and FIG. An example when the genre of R1 is “news” and the genre of the second screen region R2 is “sports” is shown.

  In the case of a combination of genres other than “sports” and a combination of genres of “sports”, the control pattern of “control 1” is applied, and the enlarged screen area is the same as in the above embodiment and modification example 1. (See FIGS. 6 and 7).

  On the other hand, as shown in FIG. 10A, when the first screen area R1 is “sports” and the second screen area R2 is “news” (other than “sports”), the control pattern “control 2” is applied. When the bar 6 moves downward and the first screen area R1 is enlarged, the volume of the first screen area R1 (“sports”) decreases, and the volume of the second screen area R2 (“news”) increases. growing. On the other hand, when the second screen area R2 is enlarged, the volume of the second screen area R2 is increased and the volume of the first screen area R1 is decreased.

  Further, as shown in FIG. 10B, when the first screen area R1 is “news” (other than “sports”) and the second screen area R2 is “sports”, the control pattern “control 3” is applied. When the bar 6 moves downward and the first screen area R1 is enlarged, the volume of the first screen area R1 (“news”) increases and the volume of the second screen area R2 (“sports”) increases. Get smaller. On the other hand, also when the second screen area R2 is enlarged, the volume of the second screen area R2 is reduced and the volume of the first screen area R1 is increased.

  As described above, according to the configuration of the modification example 2, the volume is changed in accordance with the genre of the video content in conjunction with the size change of the screen area. be able to.

  In the example of FIG. 10A, when the first screen area R1 is enlarged or reduced, the sound in the first screen area R1 may be erased (muted). Similarly, in the example of FIG. 10B, when the second screen area R2 is enlarged or reduced, the sound in the second screen area R2 may be erased (muted).

  Also in the configuration of this modification example 2, as in the above embodiment, after adjusting the volume by changing the size of the screen area, by tapping the screen area, the volume of each of the screen areas R1 and R2 is individually adjusted. Can be adjusted.

  The CPU 100 performs mode setting as to how the volume is adjusted when the screen area is tapped. FIG. 11A shows a flowchart of the mode setting operation, and FIGS. 11B and 11C show a volume adjustment table set by the mode setting operation. When the CPU 100 determines that the size of the screen area has been changed (S201: YES), the CPU 100 determines which control pattern is applied (S202). When the “control 1” pattern is applied, the CPU 100 sets the “volume adjustment table 1” shown in FIG. 11B as a table used for volume adjustment. On the other hand, when the control pattern “control 2” or “control 3” is applied, the CPU 100 sets the “volume adjustment table 2” shown in FIG. 11C as a table used for volume adjustment.

  By performing the mode setting in this way, for example, in the case of the genre combination shown in FIG. 10A, the set value of “control 2” in the volume adjustment table 2 shown in FIG. 11C is applied. As a result, even if any of the screen areas R1 and R2 is enlarged, if the user taps the first screen area R1, the volume of “sports” is further reduced, and the user can reduce the volume of the second screen area. If R2 is tapped, the volume of “News” will be further increased.

  In the configuration of the modified example 2, in the case of the combination of genres of FIGS. 10A and 10B, for example, the screen area on the “news” side is expanded from the state in which the screen area on the “sport” side is expanded. When the bar 6 is moved to the state, while the bar 6 is moving, the volume once decreases in the screen area on the “news” side and then increases again, and the sound once increases in the screen area on the “sport” side. Then it becomes smaller again. For this reason, such a change in volume may be annoying to the user.

  This can be solved by adding the following control to the CPU 100. That is, as shown in FIG. 12, the CPU 100 changes the volume if the bar 6 is continuously moved from the movement start position A of the bar 6 to the position B where the volume is the same as before the movement. The audio output circuit 111 is controlled so as not to be performed. Then, after the bar 6 exceeds the position B, the volume change control according to the volume increase / decrease table is performed according to the position of the bar 6. With such a configuration, for example, a phenomenon in which the volume is once reduced and then increased again does not occur, so that the user is not disturbed.

  In this case, if the bar 6 stops before reaching the position B and the user's finger or the like is not separated from the display screen (bar 6) in this state, it is desirable to change the volume according to the position. . Naturally, the bar 6 stops before reaching the position B, and in this state, when the user's finger or the like leaves the display screen (bar 6), the volume is changed according to the position.

  In the configuration of the second modification, a control pattern that is considered appropriate is set in advance on the device side in accordance with the combination of genres. However, depending on the user, the set pattern may not always be appropriate. .

  Therefore, a configuration in which the user can select a control pattern can be adopted. For example, as shown in FIG. 13, in the double video display mode, a selection button 13 that allows user setting is displayed at an appropriate position on the display screen, for example, at a predetermined position in the information display area of the first screen area R1. When the user presses the selection button 13, for example, the display of the button that has been “selected” is switched from “control 1” to “control 2” each time the button is pressed. Thus, the selected control pattern is set as the control pattern for volume adjustment at that time. Of course, if the selection button 13 is not pressed, a control pattern preset on the device side is applied.

  With such a configuration, the user can select a desired volume adjustment control pattern according to the genres of the two video contents displayed at that time, so that the volume adjustment according to the user's preference is performed. be able to.

  In such a configuration, it is desirable to replace the volume increase / decrease table shown in FIG. 8 with the volume increase / decrease table shown in FIG. In the volume increase / decrease table of FIG. 14, in addition to the three control patterns set as default values in the control pattern setting table of FIG. 9, a control pattern of “control 4” that can be selected by the selection button 13 by the user is set. Has been. In the control pattern of “control 4”, the volume of the first speaker device 11 is reduced when the bar 6 is moved downward (the first screen region R1 is enlarged), contrary to “control 1”. When the volume of the second speaker device 12 is increased and the bar 6 is moved upward (the second screen region R2 is enlarged), the volume of the second speaker device 12 is decreased and the first speaker device 11 is also reduced. The volume of is increased.

  With this configuration, the selection range of the control pattern for volume adjustment by the user is expanded, so that the user can perform volume adjustment according to his / her preference. For example, when the genre is “sports”, if the control pattern of “control 4” is selected instead of the control pattern of “control 1” of the default value, the user can select “sport” displayed in a large size. While watching, it is possible to confirm the status of “sports” displayed in a small size with a large volume. Thereby, the user can switch the magnitude | size of each screen area | region suitably according to the excitement situation of each sport, for example.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
