Charge accumulating and splitting imaging device |
摘要 |
Charge generated in a photodiode is properly split for difference processing. An imaging element is constituted by a semiconductor such that a charge accumulation portion is connected to a light receiving portion using a buried photodiode and charge is split from the charge accumulation portion by a plurality of gates and is accumulated. An imaging device includes a control device performing control so as to accumulate charge that is generated by a photoelectric conversion at an exposure cycle synchronous with the light emission of a light source. The exposure cycle includes a first period for receiving reflection light from a subject illuminated by light from the light source and a second period for receiving light from the subject illuminated by an environmental light not including the light from the light source. The imaging device includes a charge accumulation region connected to each photoelectric conversion region, a first charge storage region for receiving charge generated in the photoelectric conversion regions during the first period via the charge accumulation portion, and a second charge storage region for receiving charge generated in the photoelectric conversion regions during the second period via the charge accumulation portion. |
