Patent CA-1294801-C (CA)
Title: Low differential 3-d viewer glasses and method
Inventor: BEARD TERRY D
IPC: H04N13/00
Filed: 1988-04-29
Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE A method for creating a 3-D television effect is dis-closed in which a scene is recorded with a relative lateral movement between the scene and the recording mechanism (2). The recording is played back and viewed through a pair of viewer glasses (46) in which one of the lenses (18) is darker and has a spectral transmission characterized by a reduced transmissivity at at least one, and preferably all three, of the television's peak radiant energy wavebands.   The lighter lens  (20),  on the other hand,  has a spectral transmission characterized by  a  reduced  transmissivity  at  wavelengths removed from the television energy peaks.   The result is a substantially greater effective optical density differential between the two lenses when viewing television than in normal ambient light.  This produces a very noticeable 3-D effect for television scenes with the proper movement, while avoiding the prior "dead eye" effect associated with too great a density differential  in  ordinary  light.    Further  enhancement  is achieved by providing the darker lens  (18)  with a higher transmissivity in the blue and red regions than in the yellow or green regions.
