Abstract
A surveillance system is presented that aims to improve image quality. The surveillance system comprises a plurality of lighting apparatuses comprising one or more lights; a surveillance imaging device arranged to capture image data of a monitored area illuminated by one or more of the lighting apparatuses; an image processor arranged to receive the image data from the surveillance imaging device, wherein the image data comprises a plurality of frames, and the image processor is arranged to analyse each frame of the image data to obtain an image quality parameter for each frame; and a controller arranged to determine a difference between a value of the image quality parameter for a current frame and a reference value of the image quality parameter, wherein if said difference is greater than a threshold value. The controller is arranged to repeat a process of: 1) controlling a lighting parameter of at least one of the plurality of lighting apparatuses so as to change illumination of the monitored area; and 2) determining a new difference between a value of the image quality parameter for a new current frame and the reference value of the image quality parameter; until said new difference is less than or equal to a threshold value.
