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.
