FOCUS DETECTION SENSOR

摘要

A focus detection sensor and an image pickup system are provided. The focus detection sensor includes photoelectric conversion units converting light into charges, memory units storing the charges generated by the photoelectric conversion units as pixel signals, transfer units transferring the charges generated by the photoelectric conversion units to the memory units, reset units resetting the photoelectric conversion units and the memory units, a detection unit outputting a first detection signal in accordance with the pixel signals stored in the memory units, and a mode switching determination unit performing switching from a first operation mode in which the transfer units are set to a transfer state in a charge accumulation period after the photoelectric conversion units are reset to a second operation mode in which the transfer units are set to a non-transfer state.
