a pixel;
a light source that radiates irradiation light whose brightness varies periodically; and
a light emission control part that controls an irradiation timing of the irradiation light, wherein
the pixel includes:
light receiving regions, each including:
a first voltage application unit to which a first voltage is applied:
a first charge detection unit provided adjacent to the first voltage application unit;
a second voltage application unit to which a second voltage different from the first voltage is applied; and
a second charge detection unit provided adjacent to the second voltage application unit; and

a trench that is arranged at a boundary between the light receiving regions adjacent to each other, and isolates the light receiving regions from each other.
