Abstract

Systems are provided to facilitate imaging of a person or other target in an environment by providing modulated illumination to the target and to other aspects of the environment. Modulated illumination is provided to the target such that the target receives more illumination when a camera is capturing images of the target than during other periods of time. Modulated illumination is provided to background objects or other portions of the environment of the target such that the background or other non-target elements of the environment receive less illumination when the camera is capturing images than during other periods of time. In this way, imaging of a target can be improved by increasing effective illumination of the target while decreasing glare and other effects of illumination of background objects. The illumination can be modulated at a sufficiently high frequency that the illumination appears, to the human eye, to be substantially constant.
