Camera system

A method of operating 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 driven 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 method comprising the following steps, performed in a housing configured to be moveably engageable with the camera in place of the film cartridge:

• detecting a movement of the film-feeding member;
• responsive to the detecting step, generating a first signal;
• receiving a light image;
• responsive to the receiving step, generating a second signal;
• and
• storing the second signal into a memory, by generating a third signal in response to the first signal and applying the third signal to an address input of the memory.

• means for detecting a movement of the film-feeding member;
• means for generating a first signal responsive to the detecting means;
• means for receiving a light image;
• means for generating a second signal responsive to the means for receiving a light image;
• and
• means for storing the second signal into a memory, by generating a third signal in response to the first signal, and applying the third signal to an address input of the memory.
