ABSTRACT:
A display apparatus for a television having a screen of an aspect ratio different from that of an original image, wherein an image is distorted in at least one of the vertical and horizontal directions such that an expansion ratio or a reduction ratio gradually changes, and the distorted image is displayed on the screen. With the display apparatus, an image with a different aspect ratio can be displayed on the whole screen with minimally reduced missing image portions and distortion. Also, a vista size image can be displayed with an impression that a zoom-up effect is emphasized, while missing image portions are minimally reduced in left and right side portions.
