Original Abstract Submitted
power consumption is reduced. a light detection element () includes: a pixel () including a light receiving element () that receives reflected light obtained by reflecting emission light emitted from a light source device by a target object, and generates a light reception signal based on reception of the reflected light; a reflected light signal generation section () that generates a reflected light signal that is a signal having a predetermined pulse width on the basis of the light reception signal; a time code generation section () that generates a time code that is a time-series code according to an elapsed time from emission of the emission light for each specific cycle; and a time code holding section () that includes a latch circuit (d latch ) that has a data input terminal to which the time code generated is input and an enable terminal to which the reflected light signal is input and holds the time code input, outputs the time code input from an output terminal during a period in which the reflected light signal is input, and holds the time code input when input of the reflected light signal is stopped.
