MATERIALS AND METHODS FOR SIMULATING FOCAL SHIFTS IN VIEWERS USING LARGE DEPTH OF FOCUS DISPLAYS

摘要

A large depth of focus (DOF) display (Fig. 10, 54) provides an image in which the apparent focus plane is adjusted to track an accommodation (focus) of a viewer's eye(s) (32) 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 (32) is provided on the large DOF display (54). The images can be rendered in real-time, or can be pre-rendered and stored in an array. The images can alternatively be provided by a computer (132) controlled, adjustable focus video camera (136) in real-time.
