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： A color gamut of image data is appropriately subjected to a smoothing processing to print an image of favorable color reproduction and gradation reproduction. Specifically, when an average lightness is equal to or lower than a blacking lightness, the object pixel is not subjected to the smoothing processing. This can conserve the signal value of the object pixel to prevent a pixel originally having a signal value higher than the blacking lightness from being converted by the gamut compression to a black point. In this manner, a pixel for which the object pixel has the average lightness equal to or lower than the blacking lightness is blacked and a pixel having a signal value higher than the blacking lightness is not compressed to the black point. The resultant image has no deteriorated gradation characteristic when being macroscopically observed.

摘要： A pixel in a photograph region image to be subjected to blacking is subjected to a brightness modulation processing so that the pixel is modulated to any of “a pixel having the brightness to be subject to blacking” and “a pixel having the brightness not to be subject to blacking”. Specifically, the modulation by noise addition converts some pixels for which original pixel values are to be subjected to blacking to a pixel having the brightness not subjected to blacking. Thereby, “a pixel having the brightness not to be subject to blacking” thus converted has no change in brightness in the blacking processing. Consequently, a pixel at which the blacking processing is not generated can be caused to exist in the photograph image. As a result, even when the blacking processing set for character/line region is similarly set for the photograph region, the effect of the blacking can be reduced.
摘要翻译：对要进行黑化的照片区域图像中的像素进行亮度调制处理，使得像素被调制为“具有要被黑化的亮度的像素”和“不具有亮度的像素受黑“。具体来说，通过噪声加法的调制将一些要对其进行黑化的像素值的像素转换成具有不受黑化的亮度的像素。因此，如此转换的“具有不被黑化的亮度的像素”在黑化处理中的亮度没有变化。因此，可以使得不产生黑化处理的像素存在于照片图像中。结果，即使对于照片区域也设置了针对字符/行区域设置的黑化处理，也可以减少黑体的效果。

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： There is provided an image processing apparatus for applying an adjusting process to an image including multicolor image signals. An image area including a pixel to be processed is extracted, and one representative signal value is generated from signal values corresponding to a plurality of colors of pixels included in the image area (S2501). A feature amount associated with the image area is calculated based on the representative signal value (S2503, S2505, S2511), and a substitute candidate pixel common to the plurality of colors is selected from the image area based on the calculated feature amount (S2512). Signal values of the pixel to be processed are substituted by new pixel values, which are calculated from the signal values of the pixel to be processed and signal values of the substitute candidate pixel.

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.
