More Information
Summary:A range finder which irradiates a subject by emission of a light source, and receives reflected light from the subject so as to measure a distance to the subject, the range finder includes a plurality of light-source-driving circuits supplying a driving current to the light source when a light-emitting signal that controls the emission of the light source is input, wherein the light-emitting signal is output to one of the light-source-driving circuits, and each of the light-source-driving circuits has a different response speed to the light-emitting signal.
