摘要： An information processing apparatus including a read image obtainer and a setting value calculator implemented by circuitry. The read image obtainer obtains a scanned determination image, including a plurality of different dot patterns output by an image forming apparatus on a recording medium. The setting value calculator, for each of the different dot patterns of the obtained scanned determination image, determines densities of different colors of the respective dot pattern and a total number of pixels influencing the density of each coefficient of a dot gain correction filter, with respect to each target pixel. The setting value calculator further configured calculates the coefficients of the dot gain correction filter based on the determined densities of the different colors of the different dot patterns and the total number of pixels, determined for each coefficient of the dot gain correction filter and for each of the different dot patterns.

摘要： An image processing apparatus generates color conversion data in which first color component values in a first color space are associated with second color component values in a second color space. The apparatus executes determining a reference curve that takes a maximum value in the second color space among curves representing gradations of color components in the first color space; determining interpolation guide curves that represent a maximum gradation and a minimum gradation of a color component to be interpolated in the first color space; executing colorimetry on color patches corresponding to second color component values in the reference and interpolation guide curves; interpolating second color component values not included in the reference and interpolation guide curves, based on the second color component values obtained by the colorimetry; and generating the color conversion data by using the second color component values obtained by the colorimetry and the interpolation.
