摘要 An image-capturing device that captures a subject image through an exchangeable lens, a color sensor that receives the subject image and outputs color data and a white balance detection circuit that determines a white balance adjustment gain by using a correlated color temperature ascertained from the color data read out from the color sensor in correspondence to the focal point detection area used for a focal point detection at a focal point detection device are provided. If the average value of the color data read out from the color sensor does not indicate achromatic color data, the white balance detection circuit reads out the correlated color temperature having been obtained and stored in memory previously from the memory to determine the white balance adjustment R gain and the white balance adjustment B gain.
