The present invention relates to a lighting apparatus and to a lighting control method for a closed circuit television camera, which turn on LEDs in accordance with the exposure time of an imaging element in the closed-circuit television camera, and to a lighting control system interlocked with the closed circuit television camera, which turns on a plurality of lights in connection with a closed-circuit television system. For this purpose, the present invention comprises: a lamp module (120) consisting of lamps; a lamp module driver (121) which supplies power in a pulsed signal form to the lamp module (120); a synchronous signal extraction unit (130) which senses the video signal output by a camera (11) to extract a synchronous signal; and a microcomputer (110) which generates, on the basis of the synchronous signal extracted by the synchronous signal extraction unit (130), a turn-on signal in which pulses corresponding to the shutter exposure time of the imaging element of the camera are repeated using a shutter delay time as a gap, and which drives the lamp module driver (121) in accordance with the generated turn-on signal to turn on the lamp module (120) in the pulse period corresponding to the shutter exposure time. |
