ABSTRACT:
A computer outputs image data to a control circuit which in turn analyzes the content of the image data and stores pictorial image data, character image data and graphic image data in the separate designated areas of a memory circuit. The image data stored in the memory circuit is output to a halftone processor, and also to a selecting circuit. The output of the halftone processor is also supplied to the selecting circuit. The selecting circuit selects the output of the memory circuit or the output of the halftone processor in accordance with an area signal from the control circuit, and outputting the select signal to an output device, such as a printer. Thus, it is possible to output characters, graphics and halftone pictorial images with high quality even with the use of an image memory of low capacity.
