Abstract
A camera includes: a photometric unit that acquires two dimensional photometric information of an image of a photographic subject; a separation unit that separates the image of the photographic subject into two groups, based upon photometric information acquired by the photometric unit during non-emission of light by a flash light emission device; and a calculation unit that multiplies the photometric information acquired by the photometric unit during a first light emission by the flash light emission device before photography, by different coefficients for the two groups, and calculates an amount of light required for photography that is to be emitted during a second light emission by the flash light emission device, based upon the photographic information after multiplication by the coefficients.
