Classification: CPC G | IPC G

Claim 0:
1. A monitoring system for protecting a subject from harmful infrared light exposure comprising:
one or more infrared light sources configured to illuminate the subject, the illumination varying according to a predetermined time sequence;
a camera configured to capture images of the subject while the subject is illuminated by one of the light sources;
a processor circuit configured to process the captured images to determine a brightness measure of the images; and
a controller configured to control an output power of each of the infrared light sources based on the determined brightness measure,
wherein, in response to the processor detecting the brightness measure of the images below a predetermined brightness threshold, the controller is configured to switch off or reduce an output illumination intensity of an infrared light source of the one or more infrared light sources that is deemed responsible for a reduction in the brightness measure;
wherein, in response to the processor detecting the brightness measure of the images above the predetermined brightness threshold, the controller is configured to maintain the output illumination intensity of the one or more infrared light sources;
wherein the brightness measure of the images below the predetermined brightness threshold indicates that the subject is too close to the one or more infrared light sources or the subject is occluded by an object in the images.
