摘要： This invention allows printing an image with less image deterioration with respect to a document including both text and an image. An image processing apparatus includes a pixel value acquisition unit which acquires a pixel value of a pixel as a target in an input digital image, and a pixel value correction/modification processing unit which executes a correction/modification process based on the pixel value of the pixel acquired by the pixel value acquisition unit. The pixel value correction/modification processing unit includes a contrast correcting unit which executes contrast correction based on information representing a brightness value corresponding to the pixel value of the pixel, and an intermediate color removing unit which removes intermediate color in the digital image by replacing the pixel value of the pixel by pixel values of pixels around that pixel.

摘要： There is disclosed an image processing apparatus which applies an adjusting process to an image that includes a pixel to be processed. The image processing apparatus extracts an image area with a predetermined size including the pixel to be processed. The apparatus calculates a variation associated with the pixel to be processed from signal values of pixels included in the image area. The apparatus calculates a variation time count in the image area from the signal values of the pixels included in the image area. The apparatus calculates adjusting levels Fz1, Fz2, and Fe from the variation time count and the variation using a definition unit which defines correspondence among the variation time count, the variation, and the adjusting levels, and applies an adjusting process to a signal value of the pixel to be processed by the calculated adjusting levels. Note that the definition unit defines the correspondence so that the adjusting levels Fz1, Fz2, and Fe progressively change in accordance with different variation time counts or different variations.
