    摘要: An image processing apparatus includes a first halftone processor, a first filtering processor, a second filtering processor, and an evaluator. The first halftone processor generates first halftone image data from input image data using thresholds. The first filtering processor smoothes the first halftone image data using a first filter having a size corresponding to a cycle of the thresholds. The second filtering processor smoothes the input image data using a second filter having a characteristic corresponding to the first filter. The evaluator evaluates a moiré caused in the first halftone image data based on a difference between the first halftone image data smoothed by the first filtering processor and the image data smoothed by the second filtering processor.

    摘要: A 2-pixel averaging unit (101) halves an input image in the subscanning direction, and a multi-level error diffusion unit (102) performs multi-level error diffusion processing. A 2-pixel reconstruction unit (103) replaces each pixel with two pixels adjacent in the subscanning direction. A density value exchange unit (104) exchanges pixel values adjacent in the subscanning direction in each of 2×2 pixel blocks arranged in a checkered pattern in the image after replacement. High-density blocks each serving as a set of high-density dots and low-density blocks each serving as a set of low-density dots can be generated as 2×2 pixel blocks. The exposure region can be concentrated in PWM conversion.
