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