ABSTRACT:
An image processing method and apparatus which prestore a mask pattern generated using a pseudo-random number in a ROM within the apparatus, and perform image data conversion using the mask pattern. This avoids overlap between the pixel pattern of the image data and the mask pattern in a large area, and conserves the respective color densities. Accordingly, the method and apparatus enable image processing conserving the color hue and tonality of the original image data.
