PROBLEM TO BE SOLVED: To provide a depth map input device which can obtain a highly precise depth map with a small light source power, read a signal accurately without being affected by a sensitivity modulation signal, and operate with drive timing in which consumption power by modulation driving is not increased. SOLUTION: This distance depth map device is equipped with a light source for irradiating an object with a scanning light subjected to luminance modulation, an image element array which converts a light reflected from the object to an electric signal and is subjected to sensitivity modulation synchronous with the luminance modulation, and an image element driving circuit which drives the image element array and reads a signal synchronously with the scanning of the scanning light. |
