Color image processor

Abstract

A color processor which first writes each line of color data into a frame memory on the receipt of the color data from the color scanner which optically scans the color document and reads red, green, and blue components that are resolved from an individual picture element. Then, the processor reads color data before printing out the color image data via the color printer unit comprising the following elements: a memory controller, which controls the frame memory and incorporates a writing address counter and a reading address counter; an address controller which controls the writing/reading address counters; a timing circuit which controls the operations of the frame memory and the address controller by applying the predetermined drive timing; and unit for providing the timing circuit with predetermined drive timings in order that the reading of each line of color data can be synchronized with the writing of color data into the frame memory by the data-write and data-read timing clocks.
