Data recording system for cameras |
摘要 |
An apparatus and method for placing information on film takes advantage of the chemical memory of the film to use low cost displays and interface circuitry capable of displaying only a limited number of informational characters to place more than those limited number of characters on the film. This is achieved by sequentially exposing at least two separate sets of a limited number of characters on different portions of the film.
