White balance adjusting device, the white balance adjustment method, white balance adjusting program, and an imaging apparatus

摘要

A white balance adjustment apparatus comprises an area estimation unit that estimates at least one light, source color estimation area for estimating a light source color in a photographed image, a distance calculation unit that calculates a distance of the light source color estimation area in a depth direction of the photographed image as the distance of the light source color estimation area, a chromaticity calculation unit that calculates a chromaticity of the light source color estimation area, and a white balance adjustment value calculation unit that calculates a white balance adjustment value on the basis of the distance of the light source color estimation area and the chromaticity of the light source color estimation area.
