Patent ID: 8884206

Claim:
A solid-state imaging element comprising: a plurality of unit pixels, each having (i) a photoelectric conversion part, (ii) a transfer part configured to transfer a charge generated by the photoelectric conversion part to a predetermined region, and (iii) a draining part configured to drain a charge in the predetermined region; a light shielding film (i) formed entirely under an interconnect layer in the unit pixels, and (ii) configured to substantially shield the plurality of unit pixels from light except a light receiving part of the photoelectric conversion part; and a voltage controller configured to control a voltage applied to the light shielding film, wherein, the voltage controller is configured to set (i) the voltage applied to the light shielding film to a first voltage in charge draining by the draining part, and (ii) the voltage applied to the light shielding film to a second voltage higher than the first voltage in charge transfer by the transfer part.
