Image Recognition
The light pattern recognition module includes a light pattern projector that projects a light pattern directly through the display layer. 7 below illustrates a MacBook with an alternative Face ID camera system in area #750 being where Apple could integrate a "light pattern recognition module" (#750). In some examples, the light pattern recognition module be carried by the multi-function panel #760. In particular, the multi-function panel may be overlaid by a protective layer, which may help to conceal the light pattern recognition module. As the pattern of light hits the surface of the user's face, the light is reflected back towards the light pattern recognition module at various angles of incidence.
