Abstract:
A photographic image system for use with a film cartridge which houses a processed photographic film strip having an exposure area of a HDTV type aspect ratio, first and a second spaces positioned along respective edges of the processed photographic film strip between the exposure area and the respective edges of the processed photographic film strip, the first space being devoid of sprocket holes and having a hole for detection and the second space being devoid of holes, and including a leading end having an edge formed in a substantially straight line for automatic loading, the photographic image system comprising:a film feed device for feeding the processed photographic film strip between the film cartridge and a film housing; an image transforming device for transforming an image on the processed photographic film into an image signal; a detecting device for non-mechanically detecting a hole and aspect ratio information recorded on a marginal area along an edge of the processed photographic film; a processing device for processing the image signal and the aspect ratio information to generate an output signal; and a computer for controlling the film feed device and a display device to display the image signal according to an operating process, wherein the operating process has a film feed process, a detecting process that detects the aspect ratio information, and a display process that electrically displays a changed aspect ratio of the image in response to the detected aspect ratio information, and the detecting device further detects a cartridge number on one of the processed photographic film strip and the film cartridge, and the computer further displays the detected cartridge number.
