Abstract
A decision device for deciding whether an eye having a macula and an optical axis is real or false includes: lighting means emitting an infrared flux towards the eye along an entry axis; an infrared capture means for capturing an image of the eye along an exit axis, the entry and exit axes being aligned with the optical axis so that the macula illuminated by the lighting means under the incidence of the entry axis is seen by the capture means; processing means for detecting, on an image captured by the capture means, whether a peripheral zone representing the iris exists and whether a central zone in the peripheral zone, the color of which is representative of the macula existence, exists, and for delivering information representing this detection; and decision means for deciding whether the eye is real or false according to the information delivered by the processing means.
