Abstract: When a time at which a first pulsed light starts arriving at pixels after being reflected by an object is a first time, a time at which the first pulsed light finishes arriving at the pixels is a second time, and a time at which a second pulsed light starts arriving at the pixels after being reflected by the object is a third time, a control circuit decreases sensitivity of the pixels in first part of a first period from the first time including the second time, to a level lower than the sensitivity of the pixels in at least part of a second period after the first period and up to the third time, and increases the sensitivity of the pixels in second part of the first period, to a level higher than the sensitivity of the pixels in the at least part of the second period.
