A large depth of focus (DOF) display provides an image in which the
apparent focus plane is adjusted to track an accommodation (focus) of a
viewer's eye(s) to more effectively convey depth in the image. A device
is employed to repeatedly determine accommodation as a viewer's gaze
within the image changes. In response, an image that includes an apparent
focus plane corresponding to the level of accommodation of the viewer is
provided on the large DOF display. Objects that are not at the apparent
focus plane are made to appear blurred. The images can be rendered in
real-time, or can be pre-rendered and stored in an array. The dimensions
of the array can each correspond to a different variable. The images can
alternatively be provided by a computer controlled, adjustable focus
video camera in real-time.
