Abstract
A distance measurement device includes a light source; an optical system configured to emit emission light from the light source and to receive reflected light of the emission light; a plurality of pixels configured to detect the received reflected light, each including at least one sensor, and arranged in a pixel area on a substrate; and a control circuit. The control circuit is configured to: identify first reflected light detected in a first pixel in association with first emission light; and measure a distance based on a time difference between the first emission light and the identified first reflected light. The first emission light includes a first, second, and third pulse in succession. A first interval between the first and second pulse differs from a second interval between the second and third pulse.
