Abstract
A film recorder includes a digital image generator and a central processing unit operatively associated with the digital image generator for controlling the generation of images output from the image generator for recording. A film transport is provided to carry a photographic film. An image output from the image generator is projected onto a film plane of the film transport. An interface provides a data path between the central processing unit and a user accessible receptacle provided in the film recorder. A user replaceable memory element is inserted into the receptacle for communication with the central processing unit via the data path. The user replaceable memory element can provide various features. It can contain color look up tables for new photographic film types. Credit balance information can be provided in the user replaceable memory element to enable a user to make a predetermined number of exposures using the film recorder. Diagnostic information can also be stored in the replaceable memory element. The film recorder can be upgraded to incorporate new features through the use of a new replaceable memory element.
