Photoelectric transducer element |
摘要 |
A photoelectric transducer element responsive to ambient light and a combination of ambient and projected light from light emitting apparatus operates with a predetermined cycle by signals from an oscillator. This produces respective output signals which are then stored on first and second storing apparatus. Signals from the storing apparatus provide information necessary for photographing, since the storing operation is synchronized with the oscillating operation.
