ABSTRACT:
Disclosed is a color image processing apparatus, for converting source data into bit map data of each primary color, used for a color image outputting mechanism for expressing secondary colors by superposing a plurality of primary colors. This color image processing apparatus includes bit map memory having a plurality of planes, provided corresponding to the plurality of primary colors, for storing bit map data of the respective primary colors. A write control circuit is formed with a control area, within an address, for designating the plane on which source data should be written. A data converting circuit for writing the source data is provided in the plane of the bit map memory that is designated by data of this address control area. The write plane is designated within the address, and hence the writing on the plurality of planes can be performed at one time, thereby attaining a high-speed writing process.
