1. A system for presenting an object, the system comprising: a processor; a first module configured to control the processor to extract a surface position of the object whose image is captured by a computing device; a second module configured to control the processor to illuminate the object with a virtual light source combined with a real light source based on the surface position; a third module configured to control the processor to move, independent of a camera position, the virtual light source based on positional information obtained by tracking movement of the object; and a fourth module configured to control the processor to display the object as illuminated by moving the virtual light source.
