Abstract

A display device includes: a display panel that displays an input video signal; and a video recording and reproduction unit that records and reproduces a video picture to be displayed on the display panel. The video recording and reproduction unit includes an image-size setting unit that reduces a size of a screen of the input video signal according to a multi-display configuration.

Claims

1. A display device comprising:

a display panel that displays an input video signal; and

a video recording and reproduction unit that records and reproduces a video picture to be displayed on the display panel,

wherein the video recording and reproduction unit includes an image-size setting unit that reduces a size of a screen of the input video signal according to a multi-display configuration.

2. The display device according to claim 1, wherein in a case of multi-display in a two-dimensional array of M in a horizontal direction by N in a vertical direction (M and N are integers), the image-size setting unit generates a size-reduced screen of 1/M in the horizontal direction and 1/N in the vertical direction.

3. The display device according to claim 1 or 2, wherein the video recording and reproduction unit further records position information of a multi-display screen configuration.

4. The display device according to claim 1, wherein the video recording and reproduction unit further records a signal for synchronization.
