Abstract
An image processing apparatus having an arithmetic processing section for quantizing multi-density level image data and converting the image data into digital halftone image data for outputting. The arithmetic processing section is configured to create a plurality of quantized patterns to determined a dot occurrence information sequence, based on a given initial quantized pattern, such that anti-correlation is increased with respect to the dot occurrence information sequence for a pixel that has already been quantized; to add the plurality of quantized patterns to form a dither mask; and to quantize the multi-density level image data by using the dither mask.
