Storing coded color components of coded input image and coded image data received from a transmission line

摘要

An image processing apparatus receives compressed color image data and/or non-compressed color image data for each pixel and discriminates whether the received color image data is compressed or non-compressed color image data. The received color image data is processed and outputted. The color image data may be processed so that compressed image color data is expanded when the received color image data is discriminated as compressed color image data and is half-tone processed when the received color image data is discriminated as non-compressed color image data. The received color image data may be stored in a common memory represented by the same kind of plural color components and the frame data format of the compressed image data may be converted.
