A three-dimensional distance measurement apparatus include: a plurality of light sources 11 that irradiate light onto the subject； a light emission control unit 12 that controls light emission from a plurality of light sources； a light-receiving unit 13 that detects reflection light from the subject； a distance-calculating unit 14 that calculates a distance to the subject on the basis of a transmission time of reflection light； and an image processing unit 15 that creates a distance image of the subject on the basis of calculated distance data. The plurality of irradiation areas 3 onto which light from the light sources are irradiated are arranged to partially overlap only with the neighboring ones. The light emission control unit 12 individually turns on or off the light sources 11 or individually adjusts the emitted light amounts.
