<p>In a security camera system, the power to the illumination system is controlled based on the quality of the images generated by the imaging system. Specifically, the images in the frames detected by the imaging chip of the security camera are analyzed to determine whether or not there is adequate or inadequate power to the illumination system. The controller then changes the power to the illumination system until optimal illumination of the scene is achieved. Generally the power to the illumination system is reduced in response to increasing blur in the images or halos around edges in the images.</p> |
