Patent ID: 7319812

Claim:
An image processing apparatus comprising: a) a designating unit, adapted to designate a selected one of a plurality of image sizes, the plurality of image sizes being different in horizontal and vertical resolution of an image, and a selected one of a plurality of compression modes, wherein the designation of said selected one of the plurality of image sizes and the designation of said selected one of the plurality of compression modes are performed independently; b) an image pickup unit, adapted to output a digital image signal corresponding to the selected image size; c) a compression unit having a DCT unit, a quantization unit and a coding unit, adapted to compress the digital image signal, wherein said quantization unit includes a plurality of quantization parameters corresponding to the compression modes; d) an adding unit, adapted to add additional data corresponding to the image size and said compression mode designated by said designating unit to the digital image signal compressed by said compression unit; e) a recording unit, adapted to record the compressed digital image signal on a recording medium, wherein said recording unit includes a recording circuit which inputs the compressed digital image signal from said compression unit and outputs a recording signal; f) a reproducing unit, adapted to reproduce said recorded signal; and g) a display unit mounted on said apparatus, adapted to display an image signal which is output by said image pickup unit or reproduced by said reproducing unit.
