Abstract
A distance measuring device includes a light emission portion for emitting light; a light receiving portion for receiving measurement light that is emitted by the light emission portion and reflected by a measurement object, the light receiving portion comprising a plurality of pixels, each pixel having at least one light receiving portion and outputting a light reception signal that depends on the measurement light incident on the pixel; a discrimination portion for discriminating whether the pixel receives measurement light; a pixel output control portion for selectively outputting the light reception signal of each pixel individually, depending on the determination result of the discrimination portion; and an evaluation portion for receiving the light reception signals output by the pixel output control portion and outputting a distance signal that is indicative of a distance between the measuring device and the measurement object based on these light reception signals.
