PURPOSE:To simplify the constitution of the title camera and to achieve high accuracy photometry and the control of light by permitting two sensors with different light receiving angles to perform evaluation photometry and the control of light. CONSTITUTION:When a releasing signal is supplied to a control circuit 16, an exposure control mechanism 12 operates, and a stroboscope 19 emits light. 1st and 2nd light control sensors 20 and 17 receive light beams respectively and integrate them. When the integrated light receiving amount reaches a prescribed value, the light emission is stopped to terminate exposure control. With respect to light control made by the two light control sensors 20 and 17, the 1st light control sensor 20 controls the light when a specialized stroboscope is used, and the light control reference volume of the 1st light control sensor 20 is corrected according to the output difference between the two light control sensors 20 and 17. Under the simple constitution requiring a small number of parts, object brightness and background brightness are subjected to photometry, and counter light correction, delight synchronizing photographing and normal stroboscopic photographing can be performed at high accuracy. |
