Zusammenfassung:A time measurement device according to the present disclosure includes: a pixel that includes a light receiving element and a delay circuit having a variable delay time, is configured to output, as an output signal, a pulse signal that includes a received-light pulse having a pulse width corresponding to the delay time in a first operation mode, and is configured to have a ring oscillator with use of the delay circuit and configured to output, as the output signal, an oscillation signal in the ring oscillator in a second operation mode; and a time measurement section that is configured to perform time measurement processing on the basis of the output signal.
