Abstract
A three-dimensional distance measurement device includes a light emitting unit that irradiates a subject with light; a light receiving unit that detects reflected light from the subject; a distance calculation unit that calculates a three-dimensional distance to the subject on the basis of a transmission time of the detected reflected light; an image processing unit that generates a distance image of the subject on the basis of the calculated distance data; and a distance mode selection processing unit that selects a predetermined distance mode from a plurality of distance modes having different measurable distance ranges and sets a driving condition of the light emitting unit. By selecting a first distance mode in a first frame and selecting a second distance mode in a second frame, and by combining the distance data acquired in the respective frames, three-dimensional distance data of a frame to be output is generated.
