MULTI GRADATION DISPLAY METHOD

摘要

PURPOSE: A multi gradation picture display method is provided to be capable of being an error diffusion process corresponding to each digital data in a case of inputting digital data in a multi phase. CONSTITUTION: A multi gradation picture display method comprises the steps of: parallel-processing digital data corresponding to plural pixels adjacent in a scan direction by a data block; converting digital data corresponding to each pixel of the data block into gradation data for a display; display a picture on the basis of the converted gradation data; calculating a display error from a value of digital data corresponding to a note pixel; and diffusing the display error to digital data comprised to a different data block following to the data block in which the note pixel is comprised.
