<p>The present invention relates to an infrared LED camera system. The infrared LED camera system includes: an infrared LED array in which a plurality of infrared LEDs are arranged and which is disposed toward an imaging side of a camera; an imaging device unit which converts an image received through camera lenses into an electrical signal; an image signal processing unit which converts an electrical signal transmitted from the imaging device unit into a digital image signal and performs digital image signal processing; and an infrared LED control unit which controls lighting output of the infrared LED array based on digital image data output from the image signal processing unit, wherein the infrared LED control unit controls, to be higher, the lighting output of infrared LEDs set to illuminate a corresponding region in the infrared LED array with respect to a region of an image which is determined to have brightness lower than a predetermined reference value while controlling the entire lighting output of the infrared LED array to be kept high within a range where the image is not saturated.</p> |
