Abstract
In an embodiment, a method () is described. The method includes accessing () data from a sequence of images of a subject illuminated with ambient light and illumination having a sinusoidal intensity modulation in time. An imaging device is used to obtain the sequence of images and is configured such that a different spatial intensity modulation pattern is apparent in consecutive images of the sequence. The method further includes determining (), based on a set of measured pixel intensity values in each of the sequence of images, a set of revised pixel intensity values for generating a revised image of the subject such that a reduced level of ambient lighting is apparent in the revised image compared with the level of ambient lighting apparent in at least one of the sequence of images.
