摘要： PROBLEM TO BE SOLVED: To improve granularity and dot stability in multilevel error diffusion processing.
SOLUTION: An input image is halved in size in a sub-scanning direction by means of a two-pixel averaging section 101, and then is subjected to multilevel error diffusion processing by means of a multilevel error diffusion section 102. Thereafter, each pixel is replaced with two pixels adjacent in the sub-scanning direction by means of a section 103 for replacing one pixel with two pixels. For the image where each pixel has been replaced with two pixels, pixel values adjacent in the sub-scanning direction in the block are switched in each checkwise 2×2 pixel block by means of a density value switching section 104, thus forming dark blocks, each consisting of dark dots, and light blocks, each consisting of light dots, on a 2×2 pixel block-basis, and hence an exposure area can be focused during PWM conversion.
