1. A method comprising: illuminating a target area using a plurality of physical light sources, wherein each light source is positioned on a structure relative to the target area and positioned to illuminate at least a portion of the target area when activated, and wherein the illuminating comprises controlling illumination of the plurality of light sources in a sequence over a first time period, wherein at each of a plurality of points in the sequence during the first time period a different combination of one or more of the plurality of light sources are powered on to provide illumination of the target area; capturing, using a mobile device distinct from the structure, a plurality of images of the target area over the first time period representing different points in the sequence, wherein each image captures a target object that is located in the target area according to the illumination provided by that point in the sequence; evaluating the captured images including processing the captured images to generate a single composite image having respective pixel values derived from the evaluated captured images; and providing, as an output, the composite image.
