Abstract
An image-capturing device includes: an image-capturing element that captures a subject image passing through a photographic lens and outputs an image-capturing signal; a chromaticity detection device that detects a chromaticity of the subject; a light source estimating device that estimates a type of light source illuminating the subject based upon the chromaticity detected by the chromaticity detection device; a gain calculating device that calculates a gain by using color temperature information corresponding to the light source type estimated by the light source estimating device; and a gain adjustment device that performs a gain adjustment by multiplying the image-capturing signal output by the image-capturing element by the gain calculated by the gain calculating device.
