摘要

[Problem]To provide a multi-area white balance control device capable of generating an image that does not seem strange in terms of color reproduction when an entire photographic image is divided into multiple areas and the color temperature of a light source is estimated, and a white balance process is performed. [Solution]A multi-area white balance control device is equipped with: a device (11) that divides an input image into multiple areas; a device (12) that estimates the color temperature of a light source for each divided area; a device (13) that calculates color information for the image for each divided area; and a device (14) that uses the estimated color temperature of the light source for each area and the calculated color information for the image for each divided area to obtain white balance process-use information for each area. When the value of the color information for the image for a given area is high, white balance process-use information for which the multi-area white balance proportion is higher is obtained, and when the value is low, white balance process-use information for which the single-area white balance proportion is higher is obtained.
