摘要： The performance-degrading effects of unfavourable environmental lighting on face recognition systems can be assessed and quantified using a camera system operatively connected to a computer system. An assessment can be reported to the user via an appropriate output device, or stored in a storage medium for later use. The assessed lighting can then be used to alleviate the effects of unfavourable lighting conditions using one or more controllable light sources (120) that form part of a controllable lighting system. The controllable light sources (120) are located in a distributed manner relative to a camera (125), and are oriented to illuminate a subject viewed by the camera (125). An image of the subject is captured by the camera (125) and supplied to a computer system or other computing hardware. The computer system is in turn connected to a power distributor for controlling the power supplied to the controllable light sources (120).
