A camera includes a luminance distribution detecting unit, a changing point determining
unit, and an exposure controller. The luminance distribution detecting unit detects
distribution of brightness in a photographing picture. The changing point determining
unit determines a changing point of a bright portion and a dark portion with reference
to the distribution of brightness detected by the luminance distribution detecting
unit. The exposure controller decides that exposure is to be executed on the bright
portion or the dark portion based on a position of the changing point determined
by the changing point determining unit.
