Abstract

The disadvantage of requiring either a special camera or specially built expensive optical systems to place information below the image of a person for identifying photographs, or having to assemble the information from individual letters onto a name board is overcome by the name or information projector disclosed in the figure. A strip projector 10 containing 35 mm film or similar film onto which have been exposed a name and identifying number or such other desired information and subsequently developed to form a projectable transparency, is provided to illuminate screen 12 with a black and white image of the information contained on the film. The image is projected through light-shielding tube 14 onto screen 12. The screen is of a type similar to an ordinary home movie projection screen.

Name or Information Projector for Identification Pictures

The disadvantage of requiring either a special camera or specially built expensive optical systems to place information below the image of a person for identifying photographs, or having to assemble the information from individual letters onto a name board is overcome by the name or information projector disclosed in the figure. A strip projector 10 containing 35 mm film or similar film onto which have been exposed a name and identifying number or such other desired information and subsequently developed to form a projectable transparency, is provided to illuminate screen 12 with a black and white image of the information contained on the film. The image is projected through light- shielding tube 14 onto screen 12. The screen is of a type similar to an ordinary home movie projection screen. Shroud 16 is provided to shield the projection screen from ambient light conditions, thus allowing a clear image of the data projected by film strip projector 10. The top surface of shroud 16 may be adjusted such that it appears only as a line in the view of camera 18. Camera 18 is any standard 3S mm or similar type camera using either color or black and white film. This information projector can be used with either flood or strobe lighting, so long as the light is positioned relative to the subject and yet does not illuminate screen 12 during the exposure of the film in camera 18.
