  • Publication number: 20240340385
    Abstract: Depending on a degree of color degeneracy of colors of an input image after absolute colorimetric mapping, an information processing apparatus synthesizes an absolute colorimetric mapping table and a perceptual mapping table. The information processing system can acquire a first color profile for performing colorimetric color conversion, a second color profile for performing perceptual color conversion, and a parameter for increasing a distance between colors mapped through gamut mapping, and generate, based on the first color profile and the second color profile and the parameter, a third color profile.

  • Patent number: 11412107
    Abstract: An image processing apparatus performs predetermined image processing for read data obtained by reading an image on a document by first and second reading sensors arranged so as to have an overlapping area. The predetermined image processing includes color correction processing of converting color signals detected by light receiving elements of the reading sensors into color signals with respect to each of pixels forming read data. Color correction processing for first read data obtained from light receiving elements of the first reading sensor not included in the overlapping area and color correction processing for second read data obtained from light receiving elements of the second reading sensor not included in the overlapping area are performed in accordance with different correction characteristics. By doing this, an image in which image unevenness caused by individual differences of the short reading sensors is reduced can be output.
