Abstract: An interchangeable-lens imaging apparatus includes a color-temperature-information calculation circuit and a white-balance-gain calculation circuit. The color-temperature-information calculation circuit calculates color-temperature information on the basis of a first white balance gain associated with a first lens unit and first lens information of the first lens unit. The first white balance gain is calculated on the basis of a signal output from an image sensor. The white-balance-gain calculation circuit calculates a second white balance gain associated with a second lens unit that is different from the first lens unit on the basis of the color-temperature information and second lens information acquired from the second lens unit.
