Abstract:
1. A system for dynamically adjusting a level of direct illumination for an imaging system based on a level of illumination, the system comprising: a camera sensitive to at least one of infrared light or ultraviolet light; an adjustable direct non-visible light source for illuminating an area of interest with non-visible light; a light detector configured to detect a level of ambient illumination, the light detector including at least one of the camera or a light sensor, wherein: the adjustable direct non-visible light source is configured to be adjusted in response to the detected level of ambient illumination from the light detector, the camera is configured to be more sensitive to the at least one of infrared light or ultraviolet light when the adjustable direct non-visible light source is reduced, and the camera is configured to be less sensitive to the at least one of infrared light or ultraviolet light when the adjustable direct non-visible light source is increased.
