ABSTRACT:
A sensor in a camera detects code indicia on a film cartridge, representing information about the film in the cartridge, and an interface unit associated with the sensor transmits binary representations of the code to a microprocessor. A memory device contains a catalog of digital data representing information about a variety of films. The microprocessor selectively retrieves from memory those data corresponding to any of the information coded on the cartridge. Character generators, controlled by the microprocessor, effect display, preferably in the camera's viewfinder, of alphanumeric information representing the data selectively retrieved from memory.
