摘要： The quality of an image read from a degraded image of an original document can be improved. Hence, a specific pixel of an image is selected, and additional information to be added to the image is generated from the position information and color information of the selected pixel. The image of an original document is read, position information and color information added to the original document are extracted, and the color information of a pixel corresponding to the position information is acquired from the read image. The color of the read image is corrected based on the extracted color information and the acquired color information.

摘要： The color of magenta using newly developed magenta ink has characteristics L*≈41, a*≈82, and b*≈24, and has differences ΔL*≈4, Δa*≈0, and Δb*≈26 from the conventional magenta ink, i.e., the lightness value is low, and the color difference b* assumes a very small value. When the color of red is reproduced using such new magenta ink, its lightness and saturation values are low, and subdued red is reproduced, i.e., a visually favorable color cannot be obtained. Hence, when a color included in a first color gamut is input, and the input color is converted into the color of a second color gamut narrower than the first color gamut, color conversion is made using a three-dimensional lookup table having red defined by L*≈45 to 50, a*≈67 to 70, and b*≈50 to 55.
摘要翻译：使用新开发的洋红色油墨的品红色具有L *≈41，a *≈82和b *≈24的特征，并且具有差异Dgr; L *≈4，＆Dgr; a *≈0和＆Dgr; b *≈ 26，即亮度值低，色差b *呈现非常小的值。当使用这样的新品红色墨水再现红色的颜色时，其亮度和饱和度值低，并且再现低调的红色，即不能获得视觉上良好的颜色。因此，当输入包括在第一色域中的颜色并且输入颜色被转换为比第一色域窄的第二色域的颜色时，使用具有红色的三维查找表进行颜色转换，所述三维查找表由 L *≈45至50，a *≈67至70，b *≈50至55。

摘要： Print data is generated for being printed by an ink-jet printing apparatus, which has a first mode for high-speed printing and a second mode for high-quality printing, for performing multiple-pass printing by an ink-jet printhead provided with orifices for discharging ink droplets of large volume and orifices for discharging ink droplets of small volume. When the print data is generated, a user is allowed to select whether specified image data should be printed in the first or second mode. When image data is converted to print data in accordance with the mode selected, the number of ink droplets of the small volume, which are used to print an area of high density or high saturation in regard to a prescribed color in the first mode, is set to be less than the number of ink droplets of the small volume used in printing this area in the second mode.

摘要： When image data output to an ink-jet recording apparatus for performing color recording using inks of a plurality of colors is to be processed, input image data is converted into data corresponding to colors of inks and gamma correction is applied to the data corresponding to colors of inks. In this gamma correction processing, the grayscale value represented by the data is decreased to reduce the amount of shot-in ink. In the present invention, gamma correction for data corresponding to a chromatic ink differs from gamma correction for data corresponding to an achromatic ink such that higher gray level data is decreased by a smaller factor than lower gray level data for the data corresponding to the achromatic ink.

摘要： A high quality gray scale (monochrome) image in which influences of “recorded color deviation” and “color transition” are suppressed is formed even in the case of a slightly uneven discharge amount. When a gray scale (monochrome) mode is set, in the entire range of a luminance signal, density signals corresponding to achromatic dots and small chromatic dots respectively are generated based on the luminance signal so that the density signal corresponding to the achromatic dots has a greater value than that of the density signal corresponding to the small chromatic dots. Accordingly, even a slight “recorded color deviation” that occurs when the achromatic dots are recorded can be corrected by the small chromatic dots having a hue opposite to the direction of color deviation, and a high quality gray scale image in which influences of “recorded color deviation” and “color transition” are suppressed can be formed.
摘要翻译：即使在稍微不均匀的放电量的情况下也形成了其中抑制了“记录色差”和“色彩转变”的影响的高品质灰度（单色）图像。当设置灰度（单色）模式时，在亮度信号的整个范围内，分别基于亮度信号产生对应于无色点和小色点的浓度信号，使得与无色点相对应的浓度信号具有比对应于小色点的浓度信号的值更大。因此，即使在记录了无彩色点时发生的轻微的“记录颜色偏差”也可以通过具有与颜色偏差方向相反的色调的小色点校正，并且可以通过高质量灰度图像来校正“记录颜色偏差“和”颜色转变“被抑制。

摘要： A printing duty for a single scanning operation is determined for each print head of color ink used for printing. When the printing duty D is judged to be larger than or equal to a predetermined threshold value Dth, dividing printing is executed in which the printing of a area for a single scanning operation is divided into two scanning operations. This operation can reduce the printing duty of the single scanning operation to reduce the dirt on an ejection portion for ejecting inks.
