A 1.3-megapixel-resolution portable CCD electronic still camera

Portable electronic still cameras have been available for some years although, in general, the image quality has fallen short of the 35 mm film quality benchmark. To obtain improved image capture and reproduction, higher resolution CCD imagers with wider dynamic ranges must be employed in these cameras. A camera system composed of a 35 mm Nikon F3 camera body, a camera back containing a CCD-imager, and a portable hard drive for storing digitized images was constructed and employed to acquire images distributed over photospace. This paper describes the cameras hardware and capabilities, the software post-processing, the cameras characteristics, and a method for evaluating the cameras performance.
