Abstract

Improved image quality in photodetection devices that count pulses with a counter is disclosed. In one example, a first sensor unit generates a first pulse signal in response to incidence of photons. A second sensor unit generates a second pulse signal in response to incidence of photons. A first counter counts a count value in synchronization with one of a plurality of signals including the first and second pulse signals, and outputs a first digital signal indicating the count value and a first carry flag indicating whether or not overflow has occurred. A second counter counts a count value in synchronization with one of the first carry flag and the second pulse signal, and outputs a second digital signal indicating the count value.
