摘要： An image processing method is used to converting a color within a first color reproduction range that is a device-independent color space into a color within a second color reproduction range that is a color reproduction range of an output device. The image processing method includes defining, within the first color reproduction range, a third color reproduction range of a color that is estimated to be input; defining, within the second color reproduction range, a fourth color reproduction range that is smaller than the second color reproduction range; and, in performing the color conversion, compressing a color within the third color reproduction range into a color within the fourth color reproduction range and compressing a color within the first color reproduction range and outside the third color reproduction range into a color within the second color reproduction range and outside the fourth color reproduction range.

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.

There is provided a method for generating a profile used to convert a color of a first color reproduction range into a color of a second color reproduction range. The method includes dividing each of the first and second color reproduction ranges into a plurality of regions, performing color space conversion for individual regions in accordance with color space definitions unique to the individual regions, and generating a profile used to convert the color of the first color reproduction range into the color of the second color reproduction range based on color coordinates obtained through the color space conversion performed for individual regions.

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。

摘要： There is disclosed an image processing apparatus which determines an attribute of an image including a pixel to be processed. An image area having a predetermined size including the pixel to be processed is extracted (S701). A variation related to the image area is calculated based on pixel values included in the image area (S705). Pixels in the image area are converted into N-ary data (ternary data or higher) in accordance with the calculated variation (S709). The attribute of the pixel to be processed is determined by analyzing the N-ary data as a result of the N-ary conversion (S711).
