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 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 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.

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： In an ink-jet printer, when a gray is expressed by mixing ink of a plurality of colors, there is a concentration in which a use amount of the ink is large. If the gray in an edge portion of a character has the concentration of the large ink use amount, a bleeding of the ink occurs and a thin portion of the character is sometimes damaged. If the gray in the character edge portion has the concentration of the large ink use amount, the gray in the character edge portion is changed to the white side by image correction, and the damage of the character thin portion caused due to the ink bleeding is prevented.

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.
摘要翻译：图像数据的色域被适当地进行平滑处理以打印有利的色彩再现和灰度再现的图像。具体地，当平均亮度等于或低于黑色亮度时，对象像素不进行平滑处理。这可以节省对象像素的信号值，以防止原始具有高于黑色亮度的信号值的像素被色域压缩转换成黑点。以这种方式，对象像素的平均亮度等于或低于黑色亮度的像素被黑化，并且具有高于遮光亮度的信号值的像素没有被压缩到黑点。当宏观观察时，所得到的图像没有劣化的灰度特性。
