Abstract:
1. An image processing apparatus comprising: a color conversion unit that color-converts an image signal of a first color space into an image signal of a second color space by using a color conversion characteristic defining a correspondence relationship between the image signal of the first color space and the image signal of the second color space; an adjustment unit that adjusts the image signal of the second color space color-converted by the color conversion unit, in accordance with a change in the color conversion characteristic; a correction unit that corrects a conversion factor group for adjustment, the conversion factor group used when the image signal of the second color space is adjusted by the adjustment unit; a judgment unit that judges whether or not the conversion factor group for adjustment needs to be corrected by the correction unit, on the basis of a result of color measurement of a second color sample group including color samples the number of which is smaller than the number of color samples included in a first color sample group on which color measurement is performed to create the conversion factor group for adjustment to be set in the adjustment unit; and a notifying unit that notifies a user that color measurement is not necessary to be performed except on the second color sample group, or notifies the user that color measurement is necessary to be performed on at least one of the first color sample group and one or a plurality of third color sample groups, on the basis of a result of the judgment by the judgment unit for the correction of the conversion factor group for adjustment, the one and the plurality of third sample groups each including color samples the number of which is smaller than the number of color samples included in the first color sample group and larger than the number of color samples included in the second color sample group.
