Claim:
1. A multi-area white-balance control device comprising: an area divider that divides an inputted image into a plurality of division areas; a lighting-source color-temperature estimator that estimates a lighting-source color temperature in each of the division areas; an areal-image color-information calculator that calculates out color information of an areal image for each of the division areas; and a white-balance controller that acquires information for white-balance processing for each of the division areas on a basis of the lighting-source color temperature in each of the division areas estimated by the lighting-source color-temperature estimator and the color information of the areal image for each of the division areas calculated out by the areal-image color-information calculator; wherein, in acquiring the information for white-balance processing for each of the division areas, the white-balance controller considers at least one of a multi-area white-balance factor and a single-area white-balance factor in such a manner that the multi-area white-balance factor is weighted as more significant in a case where the color information of the areal image for each of the division areas has a value higher than a predetermined value, than in a case where the color information of the areal image for each of the division areas fails to have a value higher than the predetermined value.
