ABSTRACT:
The objective of the invention is to provide an image processing device that can operate at high speed even if input/output with respect to the outside is performed at low speed, and that can fully exploit processibility, by means of input line memory23and output line memory24,which can store image data of one scan line, and are arranged in the input unit and output unit, respectively; the input image data are written in input line memory23at the speed of the input image data; the image data that have been written to the input line memory are read at a speed n times faster than the input image data and are sent to processing unit25or memory unit26;processing unit25and memory unit26receive the image data of one scan line at a speed n times faster than the speed of the input image data, perform a prescribed processing, and then output the processing results at a speed n times faster than the speed of the input image data; the image data output from processing unit25or memory unit26are selected by selector29and written to output line memory24at a speed n times faster than the speed of the input image data; the output image data are read in units of one scan line from output line memory24at a prescribed speed.
