摘要： In image processing, it is possible to suppress density fluctuation and keep graininess low as well as obtain a good balance of the processing load. More specifically, when dividing multi-valued data and generating two-pass multi-pass printing data, divided multi-valued data that is common to the two passes is generated in addition to the divided multi-valued data for each of the two passes. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each pass. Furthermore, when generating quantized data, a process of generating common data by the aforementioned data division, or a process of performing quantization first without dividing the multi-valued data and then dividing the quantized 2-pass data is selectively performed according to the printing position on printing medium.

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： 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： In a multi-valued printer that uses discontinuous index patterns, if a tone correction table is generated using sampled density patches, a table which is different from a table to be obtained and has no inflection point is obtained, and the print density characteristics after tone correction suffer discontinuity. To solve this problem, an output gamma table used to output measurement patches is set to linearly correct the printer print characteristics. Patches are output and their densities are measured. A reverse table of a “signal value—density” table is generated, and is smoothed using a recursive curve. The smoothed reverse table is finely adjusted to generate an intermediate output gamma table. The generated table undergoes index component correction, thus generating a tone correction table.

摘要： Disclosed are a method and apparatus for forming a color transform lookup table which helps output a smooth image having no pseudo contour and excellent in granularity. On the basis of a previously formed table, a color space is expressed by a basic triangle of white-primary color-black, and output signal values corresponding to lattice points in this basic triangle are calculated by linear interpolation. Black ink and cyan ink are replaced by setting a straight line AB, as a boundary line, connecting two points immediately before black ink begins to be introduced on two sides of the basic triangle.

摘要： An image process method comprises an input step of inputting color image data composed of a signal representing brightness and a signal representing tint, and a smoothing process step of performing a smoothing process to the signal representing tint, while holding the signal representing brightness. Thus, high-level color noise reduction can be performed without deteriorating apparent resolution of an output color image.

摘要： The gray axis is adjusted such that an optimal representation can be achieved for low saturation colors close to the gray axis. A test pattern including a plurality of images, which have different color tones is printed, and a user selects a most desirable image. The gray axis of an image recording system is adjusted depending on which image is selected. Each of the plurality of images of the test pattern is a photographic color image represented mainly by low saturation colors close to achromatic colors along the gray axis. In accordance with the selected image, the gradation adjustment is performed for each ink color of the image recording system thereby adjusting the gray axis and the tone of colors close to the gray axis.
