Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075399
Kind Code:
A1
Abstract:
The present invention reduces a noise component caused by a dark current while eliminating the need for mechanical light shielding. This imaging device comprises: a pixel provided with a lateral overflow integration capacitor that accumulates an electrical charge which has overflowed from a photoelectric conversion unit; and a signal processing unit that carries out correction processing of a pixel signal read out from the pixel, on the basis of a virtual light shielding signal read out from the lateral overflow integration capacitor in a state in which an electrical charge which has been photoelectrically converted in the photoelectric conversion unit is not accumulated in the lateral overflow integration capacitor. The imaging device may further comprise a flow control unit that discharges an electrical charge so that an electrical charge which has been photoelectrically converted in the photoelectric conversion unit is not accumulated in the lateral overflow integration capacitor.
