Abstract
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.
Claims3
An image processing apparatus comprising:
- input means for inputting first color image data;
- coding means for coding the first color image data input by said input means so as to obtain coded first color image data having a respective plurality of coded color components;
- receiving means for receiving coded second color image data from a transmission line, the coded second color image data having a respective plurality of coded color components;
- separating means for separating each of the plurality of coded color components from others of the plurality of coded color components for the coded second color image data, said separating means separating on the basis of command data for each coded color component;
- and
- common memory means for storing the coded first color image data coded by said coding means and the coded second color image data received by said receiving means,
- wherein both of the coded first color image data and the coded second color image data are represented by the same kind of coded color components.
