摘要： To obtain a photoelectric converting apparatus of a small electric power consumption and a detecting method of a target object by using such an apparatus, the apparatus is first set to a low power source voltage mode, a reset and a transient reset are performed to a plurality of phototransistors as photoelectric converting devices and capacitors by pulses from terminals and a vertical shift register. After that, photoelectric conversion information is temporarily stored in capacitors and read out by a horizontal shift register. The read-out signal voltage is compared with a reference voltage by a comparator, thereby detecting the presence or absence of a reflection light. When the reflection light is detected, the apparatus is set to a high power source voltage mode and the reset and transient reset are again executed. After that information is read out from capacitors and is signal processed by an image processing circuit. Thus, the electric power consumption can be reduced.
