The images produced by devices such as LCD or film are arranged to form a composite or panoramic image such as a continuous 360 degree image when taken as a whole. The user can view the 360 degree image with little or no distortion at the boundaries of the image segments forming the composite image since the image producing devices have the same or nearly the same virtual optical center. | InventorAssigneeApplicationNo. 497341 filed on 06/30/1995US Classes:353/94, PLURAL348/36, PANORAMIC352/69, PANORAMIC PICTURE TYPE353/30, COMPOSITE PROJECTED IMAGE353/99PluralField of Search353/30, COMPOSITE PROJECTED IMAGE353/37, Reflector between lamp and screen353/94, PLURAL353/99, Plural353/98, REFLECTOR352/69, PANORAMIC PICTURE TYPE352/70, Mosaic picture352/71, With vignetting348/36PANORAMICExaminersPrimary: Dowling, William C.Attorney, Agent or FirmUS Patent References4890314, Teleconference facility with high resolution video displayIssued on: 12/26/1989 Inventor: Judd, et al.5016109, Apparatus and method for segmenting a field of view into contiguous, non-overlapping, vertical and horizontal sub-fields Issued on: 05/14/1991 Inventor: Gaylord5030823, Device for inspecting the inner wall of a body Issued on: 07/09/1991 Inventor: Obdeijn5153621, Optical system for projecting multiple images in adjoining relation without illuminance discontinuities Issued on: 10/06/1992 Inventor: Vogeley5194959, Image forming apparatus for forming image corresponding to subject, by dividing optical image corresponding to the subject into plural adjacent optical image parts Issued on: 03/16/1993 Inventor: Kaneko, et al.5264881, Split static surround display system Issued on: 11/23/1993 Inventor: Brooke5300966Projector Issued on: 04/05/1994 Inventor: Uehira, et al.
