Abstract
A method of adjusting a brightness of an image includes matching an object model to an object based on one or more feature points of the object extracted from an input image including the object; mapping a surface normal map in a two-dimensional (2D) image form to the input image based on the matched object model; and generating shadow information for the input image based on the mapped surface normal map and a virtual light source.
