ABSTRACT:
A ratio between an aspect ratio of a digital image signal and an aspect ratio of a display device is converted and a presence image part2of digital image data decoded by a digital image signal demodulating part is compressed laterally and is shifted to the center of an image area1made of the aspect ratio of the digital image signal and then an absence image part3is used as side panels4and digital image data made of the aspect ratio of the digital image signal is formed and outputted. Thus, even when the display device converts an image by a lateral uniform expansion method, a display image without lateral expansion can be outputted on a display screen.
