Abstract
A system utilizing aspects of both photography and electronic imaging is provided for recording and reproducing an image of scene in color. A camera component of the system photographically records the image on monochromatic film to provide a high resolution photograph from which electronic luminance signals are derived, and also utilizes an image sensor for providing lower resolution chrominance signals which are recorded on a medium, such as a magnetic stripe, that may be formed on the film unit. The photograph and chrominance signal recording are transferred to a reproduction component of the system which derives the luminance information signals from the photograph and combines it with the chrominance signals to provide three primary color signals which are utilized to drive a hard copy printer or an electronic image display device.
