<p>PURPOSE: A lighting device using an image sensor is provided to automatically control color temperature of the lighting device for emphasizing color of an object, thereby managing a change of a surrounding environment. CONSTITUTION: A light source unit(210) includes a red LED module, a green LED module and a blue LED module. A camera module(230) periodically photographs a subject. The camera module analyzes a RGB histogram of a photographed image and detects color information for emphasizing the subject. A control unit(240) controls color temperature of the light source unit based on color information provided from the camera module. A light source driving unit(220) individually drives LED modules of the light source unit.
