摘要： An image processing apparatus includes a setting unit, an averaging unit, a determination unit, a quantization unit, an addition unit and a detection unit. The averaging unit divides image data based on a division size and phase set by the setting unit to subject pixels included in the resultant respective division regions to an averaging processing to calculate an average value. The quantization unit configured to obtain a quantization value for each of the plurality of pixels. The addition unit adds the quantization values, that are obtained so that at least one of the division size and the phase is different from the other, to generate addition image data. The determination unit determines the quantization threshold value so that the quantization threshold value in a case where the division size is a first size is higher than the quantization threshold value in a case where the division size is a second size larger than the first size.

摘要： An image processing apparatus has: a generating unit configured to generate inspection target image data on the basis of read image data; a setting unit configured to set inspection target areas from the inspection target image data; and an extracting unit configured to extract a unique portion by applying a predetermined process to the set inspection target areas. The setting unit sets the inspection target areas so as to make the ratio of inspection target areas to the entire image area of the inspection target image data in a predetermined direction larger than the ratio of inspection target areas to the entire image area in a direction intersecting with the predetermined direction.

摘要： An image processor (300), a printing apparatus (100), and an image processing method are provided that can reduce, when a plurality of types of inks are used to print an image, the color unevenness that is caused by the variation of ejecting characteristics among a pluralities of nozzles. To realize this, for a color formed by overlapping at least two colors of inks, parameters are prepared that are determined so as to reduce the color difference in the printing medium (106) due to the variation of the ejecting characteristic among the respective pluralities of nozzles (101, 102, 103, 104). During printing, the parameters are used to correct the first color signal owned by the individual pixels to the second color signal.
