Abstract
A reference image of the field of view in a reference state of illumination is obtained. The display is controlled to display a first image to the object to cause the field of view to be in a first state of illumination different from the reference state of illumination. A first captured image of the field of view in the first state of illumination is then obtained. Based on the reference image and the first captured image, a position of the display relative to the object is determined.
