Abstract

Provided is a video processing device capable of displaying an easily viewable video utilizing a broader area in a display. A video processing unit that is included in the video processing device and processes an input video includes a first memory that stores the input video, a second memory that stores the input video, a compression/expansion control unit that compresses and/or expands a first area of the input video stored in the first memory and compresses and/or expands a second area of the input video stored in the second memory, and an image composing unit that generates an output video in which a video of the first area compressed and/or expanded by the compression/expansion control unit and a video of the second area compressed and/or expanded by the compression/expansion control unit are horizontally aligned.

Claims (47)

1. A video processing device comprising a video processing unit that processes an input video,

wherein the video processing unit comprises:

a first memory that stores an image corresponding to the input video;

a second memory that also stores the image corresponding to the input video;

said image stored in said first memory and said image stored in said second memory appear identical;

a compression/expansion control unit that compresses and/or expands a first area of the image stored in the first memory and compresses and/or expands a second area of the image stored in the second memory, wherein said first area and said second area are different; and

an image composing unit that generates an output video in which a video of the first area compressed and/or expanded by the compression/expansion control unit and a video of the second area compressed and/or expanded by the compression/expansion control unit are horizontally aligned, wherein

said video processing device displays said output video in which the two videos are horizontally aligned in the entire area of a display which is connected to said video processing device.

2. The video processing device according to claim 1 , wherein the first area is an upper area of the input video, and the second area is a lower area of the input video.

3. The video processing device according to claim 1 , wherein the first area is the entire area of the input video, and the second area is a rectangular area of the input video that is smaller than the entire area.

4. The video processing device according to claim 1 , further comprising a division control unit that determines whether or not a display can be made in a division display mode in which the output video generated by the image composing unit is displayed and controls the video processing unit.

5. The video processing device according to claim 4 , wherein the division control unit determines whether the input video has a boundary between an upper area and a lower area thereof and, in a case where the input video has the boundary, controls the video processing unit so as to generate an output video for performing a display in the division display mode with an upper area set as the first area and a lower area set as the second area.

6. The video processing device according to claim 4 , wherein the division control unit determines whether the input video has a boundary between an upper area and a lower area thereof and, in a case where the input video has the boundary, adds a division display mode in which the output video generated by the image composing unit is displayed as a display mode and controls the video processing unit so as to generate an output video for performing a display in the division display mode with an upper area set as the first area and a lower area set as the second area when the division display mode is selected by a user.

7. The video processing device according to claim 4 , wherein the division control unit controls the video processing unit so as to generate an output video for performing a display in the division display mode with an area disposed on an upper side of a division position set as the first area and an area disposed on a lower side of the division position set as the second area in accordance with a user's instruction including designation of the division position used for vertically dividing the input video.

8. The video processing device according to claim 4 , wherein the division control unit detects a face area from the input video and controls the video processing unit so as to generate an output video for performing a display in the division display mode with the entire area of the input video set as the first area and the face area set as the second area when the face area is detected from the input video.

9. The video processing device according to claim 4 , wherein the division control unit detects a face area from the input video, when the face area is detected from the input video, adds a division display mode in which the output video generated by the image composing unit is displayed as a display mode, and controls the video processing unit so as to generate an output video for performing a display in the division display mode with the entire area of the input video set as the first area and the face area set as the second area when the division display mode is selected by a user.

10. The video processing device according to claim 4 , wherein the division control unit controls the video processing unit so as to generate an output video for performing a display in the division display mode with the entire area of the input video set as the first area and a partial area set as the second area in accordance with a user's instruction including designation of the partial area of the input video.

11. A video display system comprising:

the video processing device according to claim 1 ; and
