IMAGE CAPTURING APPARATUS, WHITE BALANCE ADJUSTMENT METHOD, AND WHITE BALANCE ADJUSTMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image capturing apparatus for improving reproducibility of natural colors for an image captured with flash.

SOLUTION: A CPU 11 causes an image capturing unit 20 to capture an image captured with flash and a through-image without flash. A white balance gain calculation unit 15 acquires a gain value of each color component for adjusting white balance set in capturing the captured image and the through-image. An image partitioning unit 16 partitions a captured image area into plural areas. A luminance acquisition unit 17 acquires luminance values of the captured image and the through-image in the partitioned areas. A luminance comparing unit 41 calculates a value obtained by dividing a luminance value in an area of the captured image by a luminance value in an area of the through-image as a relative value, and preferentially selects plural relative values having a high value from among the calculated relative values. The white balance gain calculation unit 15 corrects the gain value of each color component of the image captured with flash based on calculated values of each color component of the captured image and the through-image and the plural selected relative values.
