1. A method, comprising: scanning light within a time-of-flight camera's field of view to illuminate a first region within said field of view that is larger than a second region within said time-of-flight camera's field of view that is illuminated at any instant by said light, wherein said scanning of light further comprises changing said second region's location within said first region in both a horizontal direction and a vertical direction within said time-of-flight camera's field of view, wherein said horizontal direction and said vertical direction are along axes that form a two-dimensional surface that faces said time-of-flight camera; and, determining depth profile information within said first region using time-of-flight measurement techniques.
