Abstract
An image processing apparatus includes an image pickup circuit having a plurality of photographic modes, such as television standards, a compression processing circuit for performing compression processing of an image pickup signal outputted from the image pickup circuit, the compression circuit having a plurality of compression modes, and a selecting circuit for selecting one of the compression modes of the compression processing circuit in accordance with a selected one of the photographic modes of the image pickup circuit.
Claims34
A method of an image data process, comprising the steps of:
- a) designating an image size selected from a plurality of image sizes and a compression mode selected from a plurality of compression modes respectively;
- b) changing the image size in accordance with designation by said designating step;
- c) compressing said changed image data in a combination of a DCT, a quantization and a coding process in accordance with designation by said designating step;
- d) adding additional data corresponding to said image size and said compression mode designated by said designating step to the compressed image data;
- e) recording said compressed image data and said added data added by said adding step on a recording medium;
- f) reproducing said compressed image data recorded by said recording step;
- g) detecting said added data recorded by said recording step;
- h) up converting an image resolution of said reproduced image data in accordance with said added data;
- and
- i) displaying said image data up converted by said up converting step.
