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.
Claims25
A method of an image 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) resizing an image signal in accordance with designation by said designating step;
- c) compressing said resized image signal 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 signal;
- e) recording said compressed image signal and said added data added by said adding step on a recording medium;
- f) reproducing said compressed image signal recorded by said recording step;
- g) detecting said added data recorded by said recording step;
- h) converting image resolution of said reproduced image signal in accordance with said added data;
- and
- i) displaying said image signal converted by said converting step.
A method of a movie image 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) resizing a movie image signal in accordance with designation by said designating step;
- c) compressing said resized image signal 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 movie image signal;
- e) recording said compressed movie image signal and said added data added by said adding step on a recording medium;
- f) reproducing said compressed movie image signal recorded by said recording step;
- g) detecting said added data recorded by said recording step;
- h) converting image resolution of said reproduced movie image signal in accordance with said added data;
- and
- i) displaying said movie image signal converted by said converting step.
The image process apparatus, comprising:
- a) designation unit, adapted to designate an image size selected from a plurality of image sizes and a compression mode selected from a plurality of compression modes respectively;
- b) resize unit, adapted to resize an image signal in accordance with designation by said designation unit;
- c) compression unit, adapted to compress said resized image signal in a combination of a DCT, a quantization and a coding process in accordance with designation by said designation unit;
- d) adding unit, adapted to add additional data corresponding to said image size and said compression mode designated by said designation unit to the compressed image signal;
- e) recording unit, adapted to record said compressed image signal and said added data added by said adding unit on a recording medium;
- f) reproducing unit, adapted to reproduce said compressed image signal recorded by said recording unit;
- g) detecting unit, adapted to detect said added data recorded by said recording unit;
- h) converting unit, adapted to convert image resolution of said reproduced image signal in accordance with said added data;
- and
- i) display unit, adapted to display said image signal converted by said converting unit.
