摘要： An ink jet printing apparatus includes a print head that is an array of a plurality of nozzles arranged according to each color of ink in a predetermined direction. The apparatus is provided with a plurality of print modes, each using a different number of colors of ink for printing. In a print mode using a smaller number of colors of ink for printing (e.g., a monochrome print mode) out of the plurality of print modes, a print method is adopted, in which an image of a predetermined area is formed by a greater print pass count than the print pass count for the predetermined area in a print mode using a greater number of colors of ink for printing (e.g., a color print mode).

摘要： Provided is an image processor and image processing method that are capable of suppressing both density unevenness and graininess that occur due to deviation of the printing position of dots that are printed by a plurality of relative movements (or a plurality of printing element groups). In order to accomplish this, the dot overlap rate of an image characteristic in which density unevenness stands out is made higher than the dot overlap rate of an image characteristic in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to an image characteristic, and to output an image having no density unevenness or graininess.

摘要： Inputted image data is converted to M number of multi-value data having a lower resolution than the inputted image data, and after quantization processing has been performed for each of the M number of multi-value data, an image is printed by M number of relative movements (M-pass printing) that corresponds to the M number of quantized data. By doing so, when compared with the case in which a resolution reduction process is not performed, it is possible to suppress the number of pixels that become the object of quantization processing, and it becomes possible to output an image with no fluctuation in image density or density unevenness without a decrease in the processing speed.

摘要： Provided are an image processor and an image processing method that are capable of suppressing both density unevenness due to printing position shifts among a group of dots printed by a plurality of relative movements (or a plurality of printing element groups) and graininess. In order to accomplish this, a dot overlap rate in the printing mode in which the density unevenness stands out is made higher than the dot overlap rate in the printing mode in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to the image characteristic, and output an image having no density unevenness or graininess.

摘要： An image processing apparatus and an image processing method are provided which, when forming an image using a plurality of different inks, can produce a satisfactory image free from problematical levels of density unevenness, graininess and insufficient density with any of these inks. To this end, when printing on pixel areas of a print medium by a plurality of relative movements between the printing unit and the print medium, the dot overlap rate of an ink that tends to show density unevenness is set higher than that of an ink that tends to show other image impairments more conspicuously than the density unevenness. This results in a good image that eliminates such image impairments as density unevenness, graininess and density insufficiency in the entire color gamut.

摘要： When dividing multi-valued data and generating data for two-pass multi-pass printing, in addition to divided multi-valued data that are divided for each of the two passes, divided multi-valued data that is common to both of the two passes is generated. Moreover, quantized data of that common multi-valued data is reflected onto the quantized data for each pass. Furthermore, when generating quantized data, division ratios that are used when generating the common data by the multi-valued data division described above are set according to the image characteristics (whether or not the area is flesh color) of the multi-valued data. Thereby, it is possible to perform high-quality printing regardless of the image characteristics by taking a suitable balance between suppressing density unevenness and suppressing graininess.

摘要： A high-quality monochrome photographic image is formed using a high-resolution color ink-jet recording apparatus. When a monochrome mode is selected, density signals are produced such that they include at least one density signal corresponding to a chromatic color material and a density signal corresponding to an achromatic color material and having a value greater than the value of the at least one density signal corresponding to the chromatic color material. A slight recorded color deviation that can occur when the achromatic color material is recorded on a recording medium is compensated for by adding a small amount of chromatic color material having a hue which cancels out the recorded color deviation. Thus, a high-quality gray scale image is obtained without having recorded color deviation or color transition.

摘要： In an image processing for printing a monochrome image, color deviation can be suppressed to print a favorable monochrome image. Specifically, the printing of a monochrome image is performed by using black ink in all of a color reproduction region (color gamut) including a gray axis and regions other than the gray axis. This avoids the use of C, M, and Y for the expression of the monochrome image to suppress the color deviation due to slight imbalance among amounts of three colors of inks.
