摘要
There is provided a system (100) comprising a light source (110), an imaging unit (120) configured to capture a plurality of images of an subject, wherein each of the plurality of images is captured at an exposure time shorter than the wave period of the pulsed illumination, wherein the pulse frequency of the illumination is not a multiple integral of the frame rate at which the images are captured, and wherein a total time during which the plurality of images is captured is at least half of the wave period of the pulsed illumination, and a control unit (130) configured to: obtain a predetermined number n of candidate images, generate a sorted list of pixels by sorting respective pixels, apply a set of weights to the respective sorted list of pixels, and generate an estimated ambient light corrected image based on the plurality of weighted and sorted lists of pixels.
