Display control device, display control method and display control program

A display control device that controls a one-picture mode in which video is displayed in a single region on a screen and a two-picture mode in which video is displayed in each of first and second regions on said screen, comprising:

• a first operation input portion that receives a first operation input caused by a user operation;
• and
• a controller that controls display of the video in said one-picture mode and said two-picture mode, wherein
• said controller,
• when a picture mode is said one-picture mode, in response to said first operation input from said first operation input portion, changes the picture mode to said two-picture mode, displays the video that has been displayed in said one-picture mode in said second region and new video in said first region and sets said first region to an operable region,
• when the picture mode is said two-picture mode and said second region is set to the operable region, in response to said first operation input from said first operation input portion, changes the operable region to said first region,
• when the picture mode is said two-picture mode and said first region is set to the operable region, in response to said first operation input from said first operation input portion, increases said first region in size and reduces said second region in size, and
• when the picture mode is said two-picture mode and said first region attains a maximum size in said two-picture mode, in response to said first operation input from said first operation input portion, changes the picture mode to said one-picture mode and displays the video that has been displayed in said first region in said single region.

A display control device that controls a one-picture mode in which video is displayed in a single region on a screen and a two-picture mode in which video is displayed in each of first and second regions on said screen and sound corresponding to the video of the first or second region is output, comprising:

• a first operation input portion that receives a first operation input caused by a user operation;
• a picture mode operation input portion that receives a picture mode operation input caused by a user operation;
• a sound operation input portion that receives a sound operation input caused by a user operation;
• and
• a controller that controls display of the video in said one-picture mode and said two-picture mode, wherein
• said controller
• changes a picture mode to said two-picture mode in response to said picture mode operation input from said picture mode operation input portion when the picture mode is said one-picture mode,
• changes the picture mode to said one-picture mode in response to said picture mode operation input from said picture mode operation input portion when the picture mode is said two-picture mode,
• changes an operable region to said first region in response to said first operation input from said first operation input portion and changes a region of video to which output sound corresponds to said first region in response to said sound operation input from said sound operation input portion when the picture mode is said two-picture mode and said second region is set to the operable region and the region of video to which output sound corresponds.

A display control method for controlling a one-picture mode in which video is displayed in a single region on a screen and a two-picture mode in which video is displayed in each of first and second regions on said screen, comprising the steps of:

• when a picture mode is said one-picture mode, in response to a first operation input from a first operation input portion, changing the picture mode to said two-picture mode, displaying video that has been displayed in said one-picture mode in said second region and new video in said first region and setting said first region to an operable region;
• when the picture mode is said two-picture mode and said second region is set to the operable region, in response to said first operation input from said first operation input portion, changing the operable region to said first region;
• when the picture mode is said two-picture mode and said first region is set to the operable region, in response to said first operation input from said first operation input portion, increasing said first region in size and reducing said second region in size;
• and
• when the picture mode is said two-picture mode and said first region attains a maximum size in said two-picture mode, in response to said first operation input from said first operation input portion, changing the picture mode to said one-picture mode and displaying video that has been displayed in said first region in said single region.

A display control method for controlling a one-picture mode in which video is displayed in a single region on a screen and a two-picture mode in which video is displayed in each of first and second regions on said screen and sound corresponding to the video of the first or second region is output, comprising the steps of:

• changing a picture mode to said two-picture mode in response to a picture mode operation input from a picture mode operation input portion when the picture mode is said one-picture mode;
• changing the picture mode to said one-picture mode in response to said picture mode operation input from said picture mode operation input portion when the picture mode is said two-picture mode;
• changing an operable region to said first region in response to a first operation input from a first operation input portion when the picture mode is said two-picture mode and said second region is set to the operable region and a region of video to which output sound corresponds;
• and
• changing the region of video to which output sound corresponds to said first region in response to a sound operation input from a sound operation input portion.

A display control program that is executable by a computer and controls a one-picture mode in which video is displayed in a single region on a screen and a two-picture mode in which video is displayed in each of first and second regions on said screen, causing said computer to execute the processes of:

• when a picture mode is said one-picture mode, in response to a first operation input from a first operation input portion, changing the picture mode to said two-picture mode, displaying video that has been displayed in said one-picture mode in said second region and new video in said first region and setting said first region to an operable region;
• when the picture mode is said two-picture mode and said second region is set to the operable region, in response to said first operation input from said first operation input portion, changing the operable region to said first region;
• when the picture mode is said two-picture mode and said first region is set to the operable region, in response to said first operation input from said first operation input portion, increasing said first region in size and reducing said second region in size;
• and
• when the picture mode is said two-picture mode and said first region attains a maximum size in said two-picture mode, in response to said first operation input from said first operation input portion, changing the picture mode to said one-picture mode and displaying video that has been displayed in said first region in said single region.

A display control program that is executable by a computer and controls a one-picture mode in which video is displayed in a single region on a screen and a two-picture mode in which video is displayed in each of first and second regions on said screen and sound corresponding to the video of the first or second region is output, causing said computer to execute the processes of:

• changing a picture mode to said two-picture mode in response to a picture mode operation input from a picture mode operation input portion when the picture mode is said one-picture mode;
• changing the picture mode to said one-picture mode in response to said picture mode operation input from said picture mode operation input portion when the picture mode is said two-picture mode;
• changing an operable region to said first region in response to a first operation input from a first operation input portion when the picture mode is said two-picture mode and said second region is set to the operable region and a region of video to which output sound corresponds;
• and
• changing the region of video to which output sound corresponds to said first region in response to a sound operation input from a sound operation input portion.
