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.

摘要： An image reading apparatus, an image reading method and a program are provided for favorably correcting color misalignment in a sub-scanning direction of a read signal read by a plurality of line sensors without increasing a circuit scale or processing time. To accomplish this, the image reading apparatus sets, as a reference signal, the read signal that is output from one of the plurality of line sensors, and detects a correlation between the reference signal and each of a plurality of read signals output from line sensors other than the one of the plurality of line sensors of a plurality of lines that are displaced in predetermined line units from a line from which the reference signal is read, and selects a read signal having a high correlation with the reference signal as a read signal from the line of the reference signal.
