Abstract
An optical sensor for appropriately updating a crosstalk value is provided with: a photon-counting type of first light-receiving unit for receiving target object reflected light and cover panel reflected light; and a determination circuit that determines whether or not the target object reflected light is received by the first light-receiving unit, on the basis of a first received light pulse signal that is based on at least one of the target object reflected light and the cover panel reflected light, and a reference pulse signal.
