Abstract
Abstract This invention discloses an accessory utilizing a light emitter, including the light emitter, arranged near a transparent body, for intermittently emitting light upon reception of an electrical signal, first pulse generator for generating a first pulse signal at a relatively short pulse interval, photo detector for detecting light incident on the transparent body and generating a light detection signal, second pulse generator for generating a second pulse signal at a relatively long pulse interval, and signal processor for receiving the first pulse signal, the second pulse signal, and the light detection signal and supplying the electrical signal to the light emitter at a predetermined timing.
