Abstract:
Because the spectral characteristics of an original of a printing sheet and those of an original of a photographic image are different, in the case where the same color conversion table is applied at the time of color conversion processing, a deviation occurs in color reproducibility. By determining the sheet type with accuracy based on the feature of fiber that occurs in manufacture of paper and by applying color conversion processing in accordance with the determination result, a highly accurate color reproduction method of an image is implemented.
