Abstract
A user selects a predefined aspect ratio format of an image displayed on a display screen. When a change in an aspect ratio format of an incoming signal occurs, that would, otherwise, produce a distorted image, a format controller automatically overrides the user's predefined aspect ratio for establishing a different image aspect ratio. Thereby, the distortion of the image is prevented.
