Still image recording apparatus which selectively compresses single image information at a first compression ratio and a second compression ratio and to decompress the compressed single image information for display before main storage

摘要

A still image recording apparatus for compressing and storing image information comprises a compression unit for compressing the same image information at a plurality of different compression ratios, and a memory for storing the image data compressed by the compression unit at the different compression ratios, collectively. It further comprises a selector for setting a combination of compression ratios to the compression unit. The selector selects the combination of compression ratios based on a degree of complexity of the input image information.
