Abstract
In an embodiment, a method () is described. The method is a computer-implemented method. The method comprises receiving () pixel information corresponding to at least part of a first, second and third image, acquired by an imaging system, of a subject illuminated by temporally modulated illumination. A time delay between an acquisition start time of the first, second and third images is such that there is an overlap in time during acquisition of the first, second and third images. The method further comprises determining () modified pixel information for constructing a modified image of the subject. The modified pixel information is determined based on: a difference between the received pixel information of the first, second and third images to reduce an effect of ambient lighting in the received pixel information; and a combination of the received pixel information to cancel out a spatial intensity modulation pattern apparent in each of the first, second and third images. The spatial intensity modulation pattern is due to a timing relationship between an imaging time period over which the imaging system acquires each image and a modulation time period of the temporally modulated illumination.
