ABSTRACT:
This invention provides a continuous display with non-uniform pixel density, forming a foveated display. A single, continuous display has a higher pixel density at the center of the display than at the periphery of the display. Where two continuous displays are used in accordance with the present invention, the central forward gaze of the viewer's image will be displayed in high resolution while the leftmost portion of the left eye display will be in low resolution and the rightmost portion of the right eye display will be in low resolution. The pixel resolution of the visual display may correspond to the visual acuity of the human eye. A foveated image display system using a continuous display with non-uniform pixel density increases the field of view while reducing the image bandwidth. A foveated image display system may be hardware-based by employing anamorphic lenses or sensors rather than relying upon image interpolation to modify the resolution of the resultant image data communicated to the continuous display with non-uniform pixel density.
