Patent ID: 7551206

Claim:
An image-capturing apparatus comprising: an image-capturing unit shooting a subject to generate an image thereof; a recording unit recording thereon one or more of color reproduction matrices in association with each of a plurality of kinds of illuminants including natural light and at least one kind of artificial illumination device; a white balance gain calculating unit calculating an evaluated value relating to a white balance gain to be applied to the image; a computing unit selecting at least two of the color reproduction matrices which are associated with different kinds of illuminants from the color reproduction matrices recorded on said recording unit based on the evaluated value, and computing a correction color reproduction matrix based on at least two of the color reproduction matrices being selected by interpolation processing; and a color reproduction processing unit applying color reproduction processing to the image generated by said image-capturing unit, by using the corrected color reproduction matrix, wherein said computing unit expresses the kinds of illuminants associated with the color reproduction matrices recorded on said recording unit as loci in system of coordinates in a color space, and computes the corrected color reproduction matrix through interpolation processing by determining a weighted average of the color reproduction matrices based on position coordinates in the system of coordinates.
