Abstract
A pattern image generation device which is able to generate various patterns by use of a RAM for processing ordinary image data and also is able to generate the patterns in a simple structure. The pattern image generation device includes an image conversion processor for converting an input image data signal to output a converted image data, the image conversion processor including rewritable memory and address controller for controlling a memory address of said memory, and an operation processor for controlling the operation of the image conversion processor.
Claims8
A pattern image generation device for a color image processing system comprising:
- an image conversion processing means for converting an input image data signal to output a converted image data, said image conversion processing means including rewritable memory means and address control means for controlling a memory address of said memory means;
- and
- an operation processing means for controlling the operation of said image conversion processing means;
- said address control means including a variable address generation means for generating a variable address signal in accordance with a synchronizing signal output from said operation processing means, and a signal select means for selecting one of said input image data signal, an address signal output from said operation processing means and said variable address signal in accordance with a control signal from said operation processing means, and wherein said operation processing means outputs to said memory means one of conversion data used to convert said input image data signal to be set in said memory means and predetermined pattern generation data to be set in said memory means in synchronization with said control signal, and said operation processing means controls said signal select means to select one of said input image data signal and said variable address signal.
