Abstract
A photoelectric conversion device including a plurality of pixels, each of the plurality of pixels including: a photoelectric conversion unit configured to generate charges according to incident light; a charge holding unit; a first transfer transistor configured to transfer charges from the photoelectric conversion unit to the charge holding unit; a second transfer transistor configured to transfer charges from the charge holding unit to a first node; and a third transfer transistor configured to transfer charges from the photoelectric conversion unit to a second node. In one of the plurality of pixels, first reading processing of reading a gradation signal indicating a light amount of the incident light based on the charges transferred to the first node and second reading processing of reading an event signal indicating a change in the light amount of the incident light based on the charges transferred to the second node are performed in parallel.
