An apparatus captures a digital image from a film-based camera having a chamber
to receive a film cartridge and a take-up spool to advance the film after each
shot. The apparatus includes a cartridge shaped to fit in the camera film chamber,
the cartridge including a processor, a storage unit coupled to the processor, and
an input output unit coupled to the processor. The cartridge houses a flexible
strip having one end coupled to the cartridge and the other end adapted to be wound
on the camera take-up spool, the flexible strip containing one or more imaging
arrays deposited thereon to capture the digital image, each of the imaging arrays
communicating with the processor.
