ABSTRACT:
A screen is disclosed for viewing depth of field images. The screen includes a curved prismatic screen mounted between a flat image and a viewer. A light hood may be provided to reduce glare and other effects of ambient light. Further protection from ambient light may be provided by coating the screen with an anti-reflective coating. Image quality for a video image or the like is provided by restructuring the image into smaller image elements. The present invention may find particular application in medical and obstetric imaging such as sonograms, musculo-skeletal imaging, vascular imaging, angiograms, angioplasty, dental probes, catheter probes, ear probes, endoscopy, laparoscopy, pelviscopy and arthroscopy.
