Abstract
A user can capture an image of an object, using a computing device, to obtain information about that object. If a specular highlight (or other saturated region) is detected, the device can attempt to determine a location of a light source associated with the highlight. The device can then provide instructions as to a direction to move in order to reduce the presence of the specular highlight in subsequent images. Multiple images of the object can be captured and analyzed to generate a three-dimensional reconstruction of the environment, whereby a position of the light source can be determined. In other embodiments, movement of the specular reflections in response to movement of the device is used to determine a direction of the light source. In other embodiments, an image of the user is captured to determine the position of the light source based on shadows or reflections on the user.
