摘要： There is provided with an information processing apparatus. A first obtaining unit obtains data of a reference image indicating a target of printing output to be performed by a printing apparatus. A second obtaining unit obtains data of an image printed by the printing apparatus. A correcting unit corrects a local image density difference or the reference image based on a global image density difference between the reference image and the printed image. An evaluating unit evaluates quality of the printed image based on the local image density difference between the corrected reference image and the printed image.

摘要： This invention converts input color data into output color data using a table which has been created based on spectral data generated by an appropriate generation method and indicates the correspondence between an input chromaticity and an output chromaticity. To do this, an input color data acquisition unit converts input color data into input chromaticity data. An output chromaticity data calculating unit converts the input chromaticity data into output chromaticity data by referring to an LUT indicating the correspondence between an input chromaticity and an output chromaticity. An output color data calculating unit converts the output chromaticity data into output color data using a conversion coefficient calculated from the input color data. The table indicating the correspondence is created based on spectral data generated by a generation method different for each of a low chroma color and a high chroma color.

摘要： To decide an efficient tone-conversion characteristic by which it is possible to reduce tone loss while suppressing the occurrence of a visual tone gap, an image processing apparatus that decides a tone-conversion characteristic for converting an M level input image into an N level output image, the apparatus decides a maximum d at which a difference between a luminance value Y(i) corresponding to an ith level of the input image and a luminance value Y(i+d) corresponding to an (i+d)th level does not exceed a given threshold; and sets, based on the d decided by the decision unit, the tone-conversion characteristic so that the ith level and the (i+d)th level of the input image respectively correspond to a jth level and a (j+1)th level of the output image.

摘要： An input chromaticity data calculation unit 113 calculates input chromaticity data rg from device-dependent color data RGB. A chromaticity data transformation unit 114 transforms the input chromaticity data rg into output chromaticity data xy by referring to an LUT stored by an LUT storage unit 13. A total amount calculation unit 115 refers to the LUT of the LUT storage unit 13 to calculate a total amount Σ′XYZ of the device-independent color data XYZ from the color data RGB. An output color data calculation unit 116 uses the total amount Σ′XYZ to calculate color data XYZ from the output chromaticity data xy.
