Claim:
A system configured to operate with a hand-held camera, the hand-held camera being configured to operate with a film cartridge, the film cartridge comprising a housing having a front wall defining an exposure aperture across which a film can be intermittently moved for exposure, the housing being configured to rotatably support a coil of film so that the film can be guided past the exposure aperture, the front wall defining an opening to enable entry of a film-feeding member into engagement with film edge perforations, the film-feeding member being driven by the camera for movement in a rectilinear path whereby successive film edge perforations are engaged so as to intermittently move the film past the exposure aperture, the system comprising: a housing configured to be moveably engageable with the camera, in place of the film cartridge; a detector configured to generate a first signal in response to detecting a movement of the film-feeding member; a memory in the housing, the memory including an address input; an electronic image sensor, in the housing, configured to generate a second signal; and circuitry configured to write the second signal into the memory, by generating a third signal in response to the first signal, and applying the third signal to the address input of the memory.
