ABSTRACT:
A display using interlaced scanning or a display using a partial rewriting method, in which only a part of a picture frame of a display device is rewritten and displayed, is combined with an error diffusion method resulting in an image displayed on the display device being made to be continuous. More specifically, when processing data of the first line of one band (comprising a plurality of lines) by the error diffusion method, error data produced when the final line of the immediately preceding band has been processed is stored in a memory, and error data stored in the memory is used. When processing data of the first line of a band by the error diffusion method, processing is started from data of a line a few lines above the first line.
