<p>PURPOSE:To obtain the contrast in a photographic surface which has such a feature as desired by a photographer by providing a plurality of light receiving elements which perform photometry for a plurality of parts in the photographic surface, and determining the exposure time and amount of flash light based on the outputs of the light receiving elements. CONSTITUTION:The light receiving elements P1, P2,... perform the photometry for a plurality of parts in the photographic surface. The signals corresponding to the amounts of received lights in the light receiving elements P1, P2,... when light is emitted from an auxiliary light source FL are integrated in integrators 3, 5,... via photometric circuits 1, 2,..., and sampled and held in S/H circuits 4, 6,.... When the light is not emitted from the auxiliary light source FL, the signals corresponding to the amounts of received lights in the light receiving elements P1, P2,... are sampled and held in the S/H circuits 4, 6,.... The exposure time is computed from said outputs and the output of an exposure time setting circuit 26.</p> |
