Abstract
A time measurement device according to the present disclosure includes: a first light receiving unit; a first timing detection unit; a first calculation unit; and a histogram generation unit. The first light receiving unit is configured to detect first pulse light and second pulse light. The first pulse light corresponds to emission pulse light emitted from a light emitting unit. The second pulse light includes reflected light by a target object. The reflected light by the target object corresponds to the emission pulse light. The first timing detection unit is configured to detect a first light receiving timing of the first pulse light and a second light receiving timing of the second pulse light by the first light receiving unit on the basis of an output signal of the first light receiving unit. The first calculation unit is configured to calculate a first time value by performing a subtraction process on the basis of the first light receiving timing and the second light receiving timing. The histogram generation unit is configured to generate a histogram on the basis of the first time value.
