ABSTRACT:
The invention includes a digital camera back accessory for use with a film-formatted camera of the type that includes a camera body and a film image plane. A solid state digital focal plane collects optical radiation and converts the radiation to digital signals representative of a digital image. A fiber optic taper has a first fiber array surface arranged at the camera film plane, and a second fiber array surface arranged at the digital focal plane, and provides magnification and/or demagnification between the film plane and the digital focal plane. A coupler couples the taper to the camera body such that an image at the film image plane is transferred and collected as a digital image at the digital focal plane. The focal plane can also be coupled to a computer so that camera images are collectable at the computer. Preferably, a solid state memory is included to store frames of digital image data. Since the digital camera back is an accessory, a user can attach and alternatively remove the accessory from the camera. Driver electronics can be coupled with the focal plane, and an electronics subsystem is also preferably part of the DCB for data and power control of the accessory. The DCB includes means for connecting the accessory to preexisting data paths in the camera, wherein the accessory operates in response to user functions in the camera.
