Abstract
A light detecting IC has a single light receiving element, a first signal processing circuit for processing signals outputted from this light receiving element, a pair of input terminals for receiving signals from outside, a second signal processing circuit for processing signals received from outside through the input terminals, and a switch circuit for selecting one from these two signal processing circuits and outputting results of processing by the selected signal processing circuit. A divided photodiode with two light receiving elements may be connected to the input terminals. Alternatively, another light receiving element which has a larger light receiving surface than the single light receiving element installed on the IC may be connected to one of the pair of input terminals.
