Abstract
A distance measurement apparatus includes: a control unit that makes an imaging unit acquire a plurality of first captured images corresponding to light patterns when making an optical system set the focal length to a first focal length, and that makes the imaging unit acquire second captured images corresponding to the light patterns when making the optical system set the focal length to a second focal length; a first distance measurement unit that determines presence or absence of an image blur and acquires a first distance to a subject from an image blur index value indicating an extent of the image blur; a second distance measurement unit that acquires a second distance to the subject based on triangulation; and a measurement result synthesis unit that outputs the first distance for a pixel with the image blur and that outputs the second distance for a pixel with no image blur.
