The technology disclosed herein provides various embodiments for mapping glints that reflect off from an object to light sources responsible for the glints. Embodiments disclosed herein are able to correctly map glints to light sources by capturing just a few images with a camera. Each image is captured while illuminating the object with a different pattern of light sources. A glint free image may also be determined. A glint free image is one in which the glints have been removed by image processing techniques.
