7. A method of operation of a display device for controlling brightness adaptation, the method comprising:
receiving a position signal that varies in dependence on a position of a fovea of an eye;
receiving a brightness signal that varies in dependence on brightness external to the display device; and
projecting a color image into the eye over a range of angles that varies in dependence on the position signal and on the brightness signal, such that when the brightness signal is below a predetermined threshold, the color image is confined to the fovea of the eye using the position signal, and such that when the brightness signal is above the predetermined threshold, the color image extends from a center of the fovea to outside the fovea.
