Abstract
A distance measurement apparatusincludes: a TOF camerahaving a light-emitting unit, a light-receiving unit, and a distance-calculating unitto measure a distance to the subject on the basis of light transmission time; and an image processing unitthat creates a distance image of the subject from distance data measured by the TOF camera. The image processing unitdetermines whether or not there is a detection target in the created distance image. If there is no detection target in the distance image, the light emission intensity control unitdecreases the emitted light intensity from the light source of the light-emitting unit, and the operation mode is switched to a power saving mode in which the pixel addition control unitincreases an addition ratio of a neighboring pixel signal of the light-receiving unit
