  • Patent number: 5745261
    Abstract: A printer has a scanning station where the negatives of a film are scanned zone-by-zone. One or more of the negatives are subsequently printed at a printing station by directing a beam of light through the negatives and onto a first photographic copy material. An exposure control unit adjusts the color composition and intensity of the light beam on the basis of data from the scanning station. Once a negative at the printing station has been printed in this manner, a reflector is moved into the path of the light beam between the negative and the copy material. The reflector deflects the light beam to a video camera which scans the negative line-by-line and point-by-point to generate a series of electrical signals representing an image of the negative. The signals are sent to a memory where they are combined with information about the image.
