Abstract
In an optical distance measuring device detecting a distance to an object, a light source is driven at a predetermined timing, and light from the light source is emitted to a predetermined range of a space, and reflected light corresponding to the emitted light is detected by at least one light receiving element. A detection signal corresponding to the reflected light is processed, and an SPAD calculation unit extracts a peak signal corresponding to the reflected light from an object. At this time, the distance to the object is measured according to the time from driving of the light source by an emission unit until output of a peak signal. At this time, performance for measurement of the distance to the object is changed depending on the state of the peak signal. This makes sensitivity appropriate when the distance to the object is optically detected.
