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.
Claims19
An image processing apparatus comprising:
- a) an image pickup device for outputting an image signal of a plurality of image sizes;
- b) a compression device for compressing an image pickup signal, wherein said compression device is able to set a plurality of compression ratios;
- c) designating device for designating said image size;
- d) recording device for recording the image signal compressed by said compression device on a recording medium;
- e) an adding device for adding additional data corresponding to said image size designated by said designating device to the compressed image signal;
- and
- f) a control device for controlling at least one of said image pickup device, said compression device and said recording device in accordance with the image size designated by said designating device.
An image processing apparatus comprising:
- a) an image pickup unit, adapted to output a digital image signal of a plurality of image sizes;
- b) a compression unit having a DCT unit, a quantization unit and a coding unit, adapted to compress said digital image signal, wherein said compression unit is able to set a plurality of compression ratios in accordance with said quantization unit;
- c) a designating unit having a selecting member, adapted to designate said image size;
- d) a recording unit, adapted to record a signal compressed by said compression unit on a recording medium, wherein said recording unit includes a recording circuit which inputs the compressed signal from said compression unit and outputs a recording signal;
- e) an adding unit, adapted to add additional data corresponding to said image size designated by said designating unit to the compressed image signal;
- and
- f) a control unit, adapted to control at least one of said image pickup unit, said compression unit and said recording unit in accordance with the image size designated by said designating unit.
A camera-integrated type digital recording apparatus having an image display device comprising:
- a) an image pickup unit, adapted to output a digital image signal of a plurality of image sizes that are different in horizontal and vertical resolution of the image;
- b) a compression unit having a DCT unit, a quantization unit and a coding unit, adapted to compress said digital image signal, wherein said compression unit is able to set a plurality of compression ratios in accordance with said quantization unit;
- c) a designating unit, having a selecting member adapted to designate said image size;
- d) a recording unit, adapted to record a signal compressed by said compression unit on a recording medium, wherein said recording unit inputs the compressed signal from said compression unit and outputs a recording signal;
- e) an adding unit, adapted to add additional data corresponding to said image size designated by said designating unit to the compressed image signal;
- and
- f) a control unit, adapted to control at least one of said image pickup unit, said compression unit and said recording unit in accordance with the image size designated by said designating unit.
