Abstract
An image process apparatus, for use with image data combining areas of different image characteristics such as text and photos, which achieves a predetermined target compression rate and simultaneously minimizes quality deterioration after decompression, is described. The image analysis circuit analyzes the composition of the entire image data and calculates the optimum compression parameter. The compression process is performed using a selected compression method for each predetermined block. At the time of compression, the value of the parameter is used in order to select an appropriate compression method by switching compression methods among a plurality of compression methods for each block unit. Using optimum compression minimizes the amount of memory required to store the information.
