STEREOGRAPHIC VIEWING WITH EXTENDED DEPTH OF FIELD

摘要

Apparatus (20) for viewing a stereographic display (24), which presents different, respective images for viewing by a right eye and a left eye of a viewer. The apparatus includes spectacles (26), which include right and left optical filters (34) to select the respective images for viewing by the right and left eyes. One or more optical phase plates (36) are positioned adjacent to the right and left filters and have a predefined aberration selected so as to enhance a depth of field of the eyes. A digital image processor (30) pre-processes the images presented on the stereographic display by applying a digital filter selected so as to compensate for the aberration of the optical phase plates.
