发明名称 STROBOSCOPE CONTROL CAMERA SYSTEM
摘要 PROBLEM TO BE SOLVED: To obtain a camera system capable of always obtaining a proper emitted light quantity by making the result of a calculation for correcting a normal emitted light quantity different in accordance with the fact that a normal or special system state is obtained. SOLUTION: Preliminary light emission is executed prior to normal light emission by a strobe microcomputer 200, a main capacitor C1, a Xenon tube 19, a light emission control circuit 203, etc., and the photometry of light reflected from an object in the preliminary light emission is executed by a multidivision photometry sensor. A camera microcomputer makes the calculation for correcting the light quantity of the normal light emission, with the result of the photometry. Then, the microcomputer 200, switches SWT, SWMZ, etc., discriminate whether photographing is normal one or special one from the conditions of a stroboscope, a lens, etc., to make the calculation for correcting the normal emitted light quantity different in accordance with the result of the discrimination. Thus, an easy-to-use strobe control camera system capable of executing control with the emitted strobe light quantity capable of always obtaining a proper exposure, even in any photographing can be provided.
