Patent ID: 7239354

Claim:
A digital image demodulating apparatus for demodulating and outputting a digital image signal inputted to a main body, comprising: an aspect ratio detector for detecting an aspect ratio of the digital image signal inputted to the main body, a digital image data controller, when an aspect ratio of the digital image signal detected by the aspect ratio detector is 4 to 3, at least one of (1) for laterally compressing a digital image based on the digital image signal inputted to the main body and adding side panels of a predetermined size to both sides of the digital image laterally compressed and forming the digital image with a predetermined aspect ratio before the lateral compression, and (2) for performing actions for adding side panels of a predetermined size to both sides of a digital image based on the digital image signal with a predetermined aspect ratio inputted to the main body and laterally compressing this digital image to which the side panels are added and forming the digital image with the predetermined aspect ratio and a digital image output unit configured to output the digital image formed by the digital image data controller wherein an aspect ratio of the digital image outputted from the digital image output unit is the same as the aspect ratio of the digital image signal inputted to the main body.
