Abstract: When printing an image using a plurality of inks, color unevenness caused by variations in ejection characteristics among nozzles is corrected at suitable timings in accordance with change in the color unevenness over time, and favorable image output without noticeably color unevenness is maintained. For this purpose, parameters are prepared, for colors formed by combinations of at least two colors of ink, the parameters being determined so as to reduce differences in coloration on a print medium caused by individual variations in the ejection characteristics of a plurality of nozzles. When printing, a first color signal included in individual pixels is corrected for a second color signal by using the parameters. Information regarding the ejection volume characteristics of a plurality of nozzles is acquired as appropriate, and by estimating changes in coloration from this information, suitable timings for overwriting such parameters are determined.

Abstract: Provided are an image processing apparatus and an image processing method capable of reducing color unevenness due to variations in ejection characteristics among a plurality of nozzles when printing an image using a plurality of inks. To that end, a first image which is made up a color with noticeable color unevenness and similar colors is printed onto a print medium. The user then specifies a color and a nozzle position where color unevenness has occurred. On the basis of these results, parameters are set for a correction table referenced by an MCS processor. In so doing, it becomes possible to address the factor causing the color unevenness, and mitigate the effects of color unevenness in a focused way without incurring increases in processor load, memory requirements, or processing time as compared to the case of calibrating all lattice points.

Abstract: When an input image is shifted by 640 pixels from a test pattern with reference to the position of a nozzle, the remainder is obtained by dividing 640 pixels by pixels of the dither matrix in an x direction. For example, when the size of the dither matrix in the x direction is 256 pixels, the dither matrix is shifted by 128 pixels in a direction reverse to the x direction. In this manner, the phase of the dither matrix at the time of the quantization during test pattern printing matches the phase of the dither matrix at the time of the quantization during input image printing. Consequently, unevenness of the dither matrix at a position N becomes the same in both of the test pattern and the input image. The HS correction to density unevenness caused by the unevenness of the dither matrix becomes suitable for the input image.

Abstract: As viewed for each processing unit in head shading (HS) processing, a processing unit width is more than one pixel, so that a threshold arrangement corresponding to a target quality of an image intended by a dither matrix is kept while a possibility of avoiding zero dots from being generated can be enhanced. Moreover, the threshold arrangement is kept while a possibility of generating the same number of dots in processing units can be enhanced. Consequently, the threshold arrangement corresponding to a predetermined target quality of an image intended by a dither matrix is kept while it is possible to reduce occurrence of uneven density caused by the HS processing. Thus, it is possible to prevent the threshold arrangement from being limited by the HS processing according to the degree of the reduction.

Abstract: 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.

Abstract: There is provided an image processing method in which in a full line type inkjet printer using a connecting head having an overlap region, even if a conveyance direction of a print medium is more or less inclined, a density change or degradation of graininess is not introduced. Therefore, an image data in a non-overlap region is distributed to a plurality of nozzle arrays such that ink is ejected from all the plurality of the nozzle arrays. On the other hand, a region where a print allowance rate changes in the overlap region is divided into plural regions, and the image data is distributed to the plurality of the nozzle arrays such that these regions are located to be shifted.

Abstract: 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.

Abstract: Nozzles in a print head are arrayed in a density of 600 dpi. Moreover, a dither matrix has a size of 16 pixels×16 pixels in 600 dpi. The dither matrix is repeatedly used. In the meantime, each of rectangles represents an HS processing unit. WHS=3 pixels. As a consequence, the relationship of a least common multiple below is established in a nozzle array direction: 3×WD=16×WHS. In this case, the cycle of interference unevenness can be prolonged to the least common multiple between WD and WHS, that is, 48 pixels (3WD). In this manner, the size of the dither matrix is not an integral multiple of the HS processing unit width, so that the cycle of interference unevenness can be prolonged more than the size of the dither matrix. Thus, the interference unevenness can be hardly recognized.

Abstract: In order to print a unit area of a print medium by a first printing scan and a second printing scan, dither patterns are formed which can control the arrangement of dots on the print medium without adverse effects of density unevenness and graininess, that are caused by printing position displacement. Regarding first and second dither patterns, information indicating whether or not a threshold is already set to a reference pixel and one or more pixels around the reference pixel in the first dither pattern is obtained for cases where each pixel in the first dither pattern is the reference pixel. A pixel in the second dither pattern to which a predetermined pixel is to be set is determined based on the obtained information. The first and second dither patterns formed in the above manner are associated with the first printing scan and the second printing scan, respectively.

Abstract: When an input image is shifted by 640 pixels from a test pattern with reference to the position of a nozzle, the remainder is obtained by dividing 640 pixels by pixels of the dither matrix in an x direction. For example, when the size of the dither matrix in the x direction is 256 pixels, the dither matrix is shifted by 128 pixels in a direction reverse to the x direction. In this manner, the phase of the dither matrix at the time of the quantization during test pattern printing matches the phase of the dither matrix at the time of the quantization during input image printing. Consequently, unevenness of the dither matrix at a position N becomes the same in both of the test pattern and the input image. The HS correction to density unevenness caused by the unevenness of the dither matrix becomes suitable for the input image.

Abstract: As viewed for each processing unit in HS processing, a processing unit width is more than 1 pixel, so that threshold arrangement corresponding to a target quality of an image intended by a dither matrix is kept while a possibility of avoiding the zero number of dots from being generated can be enhanced. Moreover, the threshold arrangement is kept while a possibility of generating the same number of dots in processing units can be enhanced. Consequently, the threshold arrangement corresponding to a predetermined target quality of an image intended by a dither matrix is kept while it is possible to reduce occurrence of an uneven density caused by the HS processing. Thus, it is possible to prevent the threshold arrangement from being limited by the HS according to the degree of the reduction.

Abstract: One dither mask having a highest spacial frequency is selected from a plurality of dither masks. Next, a granularity is obtained with reference to a table based on the selected dither mask and an ejection amount level per area. Moreover, a difference in granularity between adjacent areas is calculated with respect to all of the areas. A maximum value is obtained out of the obtained differences in granularity, and then, the maximum difference in granularity is compared with a determination threshold. When the maximum difference in granularity is the threshold or greater, it is determined whether or not a dither mask having a spacial frequency lower than that of the selected dither mask is stored in a memory. When there are dither masks having lower spacial frequencies, a dither mask having a spacial frequency lower by one level than that of the selected dither mask is selected.

Abstract: The present invention suppresses data processing load and processing time when generating density data for the same color that corresponds to a plurality of printing scans (or plurality of printing element groups) of a printing head and printing medium. In order to accomplish this, input image data is converted to a plurality of density data by referencing a three-dimensional lookup table that performs one-to-one correlation of input image data with a plurality of density data that corresponds to a plurality of relative movements (or plurality of printing element groups). By doing so, it is possible to perform a process of generating density data (CMYK) that corresponds to a plurality of relative movements (or plurality of printing element groups) from input image data at once, and thus it is possible to suppress an increase in data processing load and processing time.
