ABSTRACT:
A video output device adds a blank on both left and right sides or both upper and lower sides of an input video to produce a video having the same aspect ratio as that of the display screen of the display device, when an aspect ratio of the input video and an aspect ratio of a display device for displaying the video are different. At this time, the brightness of the blank to be added to the input video is adjusted in accordance with the brightness near the boundary between the input video and the blank to suppress a difference in brightness near the boundary.
