Abstract
There is provided a digital still camera which is capable of performing fixed-length compression to image data at high speed while suppressing dispersion in size of compressed data by including; a first compression unit which compresses inputted image data using a predetermined first compression parameter, a second compression unit which compresses the inputted image data using a second compression parameter different from the first compression parameter, an evaluating unit which evaluates compression results of the first compression unit and of the second compression unit based on a relationship with a predetermined range including a target size of compressed data, and a selecting unit which selectively performs recording processing to a compression result highly evaluated by the evaluating unit.
Claims6
A digital still camera which compresses image data for recording, the image data representing a digital still image photographed by a photographing unit, the digital still camera comprising:
- a first compression unit which compresses inputted image data, using a predetermined first compression parameter;
- a second compression unit which compresses said inputted image data, using a second compression parameter different from said first compression parameter;
- an evaluating unit which evaluates compression results of said first compression unit and of said second compression unit based on a relationship between the compression results and a predetermined range including a target size of compressed data;
- and
- a selecting unit which selectively performs recording processing to a compression result highly evaluated by said evaluating unit.
