Abstract
A rangefinder apparatus includes an infrared emitting diode projecting a light beam toward a target object several times; a position sensing device (PSD) for detecting light of the light beam reflected from the target object and outputting a signal corresponding to a distance to the target object; an auto-focus integrated circuit (AFIC) for processing the output signal of the PSD; and a CPU for outputting a control signal for the signal processing and a clamp setting signal for setting a clamp level to the AFIC, and a reset signal for resetting the AFIC to an initial state at an input terminal identical to that for the clamp setting signal. Since the clamp setting signal and the reset signal are fed to the same terminal, the cost of the signal processor can be reduced.
