Abstract

An image input device includes a turn-on circuit and a converting circuit for receiving light reflected at an object and converting it into an electrical signal. The image input device is connected to a laser device as an output device. The turn-on circuit includes a triangular wave generating circuit, an error amplifier, a pulse width modulator, a lamp turn-on circuit, a xenon lamp and a protection circuit. The converting circuit includes an oscillator, a system control unit having a microprocessor to control the whole image input device, and image sensors. A same clock having a certain frequency from the oscillator is supplied to the turn-on circuit and the system control unit in the converting circuit thereby controlling the turn-on circuit to synchronize with driving signals of the image sensors.
