摘要

[Problem] To provide a multi-area white balance control device capable of reproducing color without creating a feeling of strangeness even if the white balance correction gain estimation is wrong in individual areas. [Solution] The present invention has: an area division means (11) for dividing an input image into multiple areas; a white balance correction gain estimation means (12) for estimating the white balance correction gain for each of the divided areas; a white balance correction gain anomaly determination means (13) for determining whether the estimated white balance correction gain of the aforementioned area is abnormal or not on the basis of a comparison with the estimated white balance correction gains of peripheral areas adjacent to the area; and a white balance correction gain modification means (14) for modifying, on the basis of the estimated white balance correction gain of the peripheral areas adjacent to the area that was determined to be abnormal, only the estimated white balance correction gain of the area that was determined to be abnormal.
