<P>PROBLEM TO BE SOLVED: To provide a photometric device for appropriately avoiding influence of overflow. <P>SOLUTION: The photometric device 10 includes a light receiving element 9 for photo-electric-converting light from a field to output an electric signal corresponding to the light intensity, a determination unit 11 for receiving the electric signal from the light receiving element 9 to determine whether an overflow occurs in the light receiving element 9, and a control unit 11 for performing different control in calculation of accumulation time in the light receiving element 9 between a case where the determination unit 11 determines that the overflow occurs and a case where the determination unit 11 determines that the overflow does not occur. <P>COPYRIGHT: (C)2012,JPO&INPIT |
