Abstract
A distance-measuring device includes a light source, a light detector, and a circuit. The circuit causes the light source to output a light pulse toward a target object, causes the light detector to detect a reflection-light pulse in a first period and a second period to generate a first signal and a second signal, respectively, and generates and outputs data indicating a distance from the light detector to the target object based on the two signals. The first period includes at least a part of a rise period, from a first point at which an intensity of the reflection-light pulse starts increasing to a second point at which the increase ends, and the first point. The second period includes at least a part of a fall period, from a third point at which the intensity starts decreasing to a fourth point at which the decrease ends, and the fourth point.
