摘要： An image processing apparatus includes an obtaining unit, a determination unit, a setting unit, and a processing unit to perform an image edge intensifying processing. The obtaining unit obtains image data by reading a document. The determination unit determines an image edge direction. The setting unit sets an edge intensifying processing intensity based on the image data and a processing intensity determined corresponding to a difference between resolution in a main scanning direction and resolution in a sub-scanning direction. The processing unit performs the image edge intensifying processing according to the set intensity. In response to the resolution of the image data being higher in the sub-scanning direction than in the main scanning direction, the setting unit sets a higher intensity of the edge intensifying processing in response to the edge direction being along the sub-scanning direction than in response to the edge direction being along the main scanning direction.

摘要： An image processing apparatus to perform an edge intensifying processing of an image includes an obtaining unit, a calculating unit, a setting unit, and a processing unit. The obtaining unit obtains image data composed of pixels aligned in a main scanning direction and a sub-scanning direction perpendicular to the main scanning direction. The calculating unit obtains an edge direction of an image and a variation amount indicating a magnitude of change in a luminance value. The setting unit sets an intensity of the edge intensifying processing. The processing unit performs the edge intensifying processing. In a case where the image data resolution in the sub-scanning direction is higher than in the main scanning direction, the setting unit sets the intensity of the edge intensifying processing to an amount that is higher when the edge direction is the sub-scanning direction than when the edge direction is the main scanning direction.

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： Image data can be subjected to a smoothing processing to improve a color reproduction characteristic and an image free from a deteriorated gradation characteristic can be printed. Specifically, the smoothing processing improves the color reproduction characteristic. This smoothing processing may cause a color originally not having the lightness equal to or lower than blacking lightness to be converted to a color having lightness equal to or lower than the blacking lightness. To solve this, such a color is subjected to a gradation adjustment processing to convert the color to the color having the lightness higher than blacking lightness. A gamut mapping does not map such a color on a black point, thus preventing such a color from being broken by the blacking.

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.
