摘要： A display device having a display screen of 16:9 aspect ratio for displaying fully a video image of 4:3 aspect ratio without leaving a blank space and a display device having a display screen of 4 :3 aspect ratio for displaying fully a video image of 16 :9 aspect ratio without leaving a blank space are disclosed. The former device includes at least one of the first circuitry for non-linearly expanding a horizontal display scale of the 4:3 image being fully displayed to fill up the 16 :9 screen, in right and left portions of the image relative to the horizontal center of the image as such that a rate of non-linear expansion is increased as a horizontal position within the image becomes distant from a horizontal center of the image, and second circuitry for non-linearly compressing a vertical display scale of the 4:3 image being fully displayed to fill up the 16 : 9 screen, in upper and lower portions of the image relative to the vertical center of the image as such that a rate of non-linear compression is increased as a vertical position within the image becomes distant from a vertical center of the image. In the latter device, the horizontal scale is non-linearly compressed, and the vertical scale is non-linearly expanded.
