摘要

A multi-area white-balance control device includes a component that divides an inputted image into a plurality of division areas, a component that estimates a lighting-source color temperature for each division area, a component that calculates out color information of an areal image for each division area, and a component that acquires information for white-balance processing on the basis of the lighting-source color temperature and the color information of the areal image for each division in such a manner as to weight, in the information for white-balance processing, a multi-area white-balance factor as more significant in reference to a single-area white-balance factor in a case where the color information has a value higher than a predetermined value, than in a case where the color information fails to have the predetermined value. Thereby, an image with natural color reproduction can be generated.
