ABSTRACT:
A moving image data compressor/decompressor is provided that compresses moving image data with high compressibility and high image quality maintained. The image data extractor8extracts image data on a partial area with large motion in a frame. The first data compressor10compresses the image data on the partial area. The image reducer12reduces the size of the frame. The second data compressor compresses the data concerning the size-reduced frame. The compressed data output unit16holds data groups sequentially into the hard disk208,together with positional information on a partial area. Each of the data groups is formed of frame data compressed by the second data compressor14and image data on a partial area compressed by the first data compressor10,for each frame forming a moving image.
