Abstract
A system to form reduced data for indexing use classified according to specific groups. A digital still camera records image data corresponding to a photographed subject, in frame units on a recording medium, and includes a classification unit to classify the image data corresponding to the photographed subjects into specific groups and a recording control to record image data corresponding to plural frames of the specific groups classified by the classification unit.
Claims19
An image processing system, comprising:
- an image processing unit to produce digital image data corresponding to an imaged subject;
- a memory card including plural regions to receive the digital image data and to store the digital image data in a respective one of the plural regions;
- a reading unit to read the digital image data stored in the memory card automatically when the stored image data reaches a predetermined level;
- a reducing unit to reduce the digital image data read by the reading unit and to produce a reduced digital image data;
- and
- a recording unit to record the reduced digital image data in the memory card.
3 more elements
An image processing unit, comprising:
- an image processing device to generate digital image data representing a single frame image of an imaged subject;
- a main buffer memory to receive and store the digital single frame image data;
- a reducing unit to reduce the single frame image data;
- an auxiliary buffer memory having plural storage regions to receive the reduced single frame image data and to store the reduced data in a respective region in the auxiliary buffer memory;
- a compression and expansion unit to receive the digital image data from the main buffer memory and to compress the digital image data according to a first compression ratio, and to receive the reduced image data from the auxiliary buffer memory and compress the reduced image data according to a second compression ratio which is different from the first compression ratio;
- and
- a memory card to store the compressed image data.
