Abstract:
A color balance correction device includes a histogram generating unit that generates histograms of a gradation level of pixels for R, G, and B; a decreasing-tendency-area identifying unit that identifies a range that the frequency tends to decrease first from a highlight side of each of histograms generated by the histogram generating unit as the catch light area; and a correction-amount calculating unit that calculates a correction amount of the color balance using data of pixels except for those in the catch light area specified by the decreasing-tendency-area identifying unit.
