摘要
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.
