Abstract
Abstract The present invention includes an information projector slide (10) comprising a planar member having a central window for holding a photographic film image and at least one border adjacent the window. A magnetic medium for storing selected digitally encoded alpha-numeric information is affixed to the border. A read/write system for reading information from and writing information to the projector slide includes a read head (36), a write head (34), a controller (96), a keyboard (40) and a display monitor (42). An optical projection system (88) and a video projection system (74, 42) are provided for concurrently displaying an image from a photographic slide (10) and encoded information from the magnetic media. A cropping system is also provided for use with the video projection system.
