摘要： A novel system is disclosed which is suitable for addition to conventional photographic cameras for permitting recording of data such as f-stop and shutter speed annotations automatically on film as thecamera is operated in conventional photography. The system of the present invention includes a light emitting diode display mounted inside a camera back and positioned adjacent the edge portions of film within the camera. A pair of rotary or slide switches are mechanically coupled to the f-stop and shutter speed controls of the camera to trigger the appropriate light emitting diodes for recording the camera settings on the edges of the film. The system may be incorporated into new cameras as they are manufactured, or it may be distributed as a kit for addition to existing cameras.
