Patent ID: 8319891

Claim:
A video display device, comprising: a receiver configured to receive an operation instruction from a user, a video converter for extending an inputted video in at least one of a horizontal direction and a vertical direction; and a display including a display screen whose physical viewable area aspect ratio is longer in the horizontal direction than 16:9 and adapted to display the inputted video extended by the video converter, wherein the video converter includes a mode for extending the inputted video at a scaling factor A, which is at least equal to 1 in the horizontal direction and at a scaling factor B, which is at least equal to 1 in the vertical direction; a normal mode for extending the inputted video neither in the horizontal direction nor the vertical direction; a half/full mode for extending the inputted video at a scaling factor of 4/3 only in the horizontal direction; a first zoom mode for extending the inputted video at a scaling factor of 128/63 in the horizontal direction and at a scaling factor of 8/7 in the vertical direction; and a second zoom mode for extending the inputted video at a scaling factor of 5/2 in the horizontal direction and at a scaling factor of 8/7 in the vertical direction, and wherein the video converter causes the normal mode, the half/full mode, the first zoom mode and the second zoom mode to transit from one to another in accordance with the operation instruction.
