PURPOSE: A closed circuit TV camera linkage type lamp control system is provided to generate a light period based on a sync signal extracted from a video signal. CONSTITUTION: A sync signal extraction module(140) extracts a sync signal from a video signal. A local communication module(130) performs local communication with a local communication module of a lighting controller(220). Based on extracted sync signal, a microcomputer(110) generates a lighting signal. The microcomputer transmits the generated lighting signal to the lighting control unit. The lighting control unit lights a lamp module(210) to a pulse section corresponding to a shutter exposure time.
