According to one embodiment, a distance measurement apparatus includes a light emitter that intermittently emits a light beam, and a meter that measures a distance to an object from a length of time from an emission of the light beam from the light emitter to a return of reflected light by the object. The light emitter emits the light beam in a certain cycle with delay corresponding to randomly set offset time. The meter generates an integrated detection signal by shifting a plurality of detection signals of the light beam emitted in the certain cycle by the respective offset times and time-divisionally integrating the detection signals, and determines based on the integrated detection signal whether or not the light indicated by the detection signals is reflected light by the object, emitted from the light emitter.
