摘要： A photoelectric conversion device includes pixels including first and second photoelectric converters, a memory unit, and a transfer unit for transferring signals in the memory unit to a processing unit. The pixels output a first signal based on a signal of the first photoelectric converter, and a second signal based on signals of the first and second photoelectric converters. The transfer unit performs on row-by-row a first transfer period of transferring the first signal in the memory unit and a second transfer period of transferring the second signals held in the memory unit. A column a pixel outputting the first signal transferred during the first period of a first row is arranged is different from a column a pixel outputting the first signal transferred during the first period of a second row is arranged.
