ABSTRACT:
A display controller includes an input device which inputs image data in a first form, and a processor which processes the image data and outputs a control signal which controls a display device. The processor includes a convertor which converts the image data in the first form to image data in a second form. A detector detects a partial area to be rewritten in an image by performing a comparison using the image data in the second form.
