PHOTOELECTRIC CONVERSION DEVICE

A photoelectric conversion apparatus includes a pixel region including multiple pixels arranged in an array pattern. The multiple pixels include a first pixel and a second pixel. The first pixel includes a first photoelectric converter, a first detection circuit that outputs a first detection signal based on a photon incident on the first photoelectric converter, a first output circuit that outputs a first pixel signal to outside of the pixel in accordance with the first detection signal, and a first control circuit that controls whether the first detection signal is input into the first output circuit. The second pixel includes a second photoelectric converter, a second detection circuit that outputs a second detection signal based on a photon incident on the second photoelectric converter, a second output circuit that outputs a second pixel signal to outside of the pixel in accordance with the second detection signal, and a second control circuit that controls whether the second detection signal is input into the second output circuit. The first control circuit controls whether the first detection signal is input into the first output circuit in accordance with the second detection signal.
