Abstract
A distance measurement device includes: a light source configured to emit visible illumination light; an imaging element configured to receive reflected light of the illumination light from an object; and a signal processing circuit configured to reduce the emission of the illumination light in a predetermined period, detect a timing when the reception of the reflected light at the imaging element is reduced due to the reduction of the illumination light, and measure a distance to the object on the basis of the detected timing.
