ABSTRACT:
A kit for converting a conventional slide or motion picture projector to a closed circuit television device primarily for classroom, seminar and home entertainment use, consisting of two main modules: a new lamp which substitutes for the normal projection lamp, and a lens-video camera combination which takes the place of the normal projection lens. The features and characteristics of the projector itself remain unchanged. The signal from the lens-television module can be viewed on a video screen, or recorded on a video recorder with or without modification by accessory components.
