Abstract
An electronic imaging copier is provided for making enhanced photographic copies of reflection print and transparency types of photographs. An optical image of an original print or transparency is scanned twice to provide first and second sets of image signals representative of low and higher resolution versions of the image. At least a portion of the low resolution first set of signals is employed to provide a preview display of the image. The first and second sets of signals are processed to provide a third set of signals representative of an enhanced version of the image which is projected onto a film unit to provide the photographic copy.
Claims25
An electronic imaging copier configured for print and transparency copying modes of operation for making enhanced photographic copies of reflection print and transparency types of photographs, said copier comprising:
- prising:
- means for supporting a print at a first object plane;
- means for supporting a transparency at a second object plane;
- optical means being selectively operable in the print copying mode for providing an optical image of a supported print at an image plane, and in the transparency copying mode for providing an optical image of a supported transparency at said image plane;
- photoresponsive means for sensing an image provided at said image plane and being operative to provide, in sequence, a first set of electronic image signals representative of a low resolution version of said image and a second set of electronic image signals representative of a higher resolution version of said image;
- memory means for storing said first set of signals;
- display means responsive to at least a portion of said first set of signals for displaying a low resolution version of said image;
- signal processing means for processing said first and second sets of signals to provide a third set of signals representative of an enhanced version of said image;
- means for supporting a photosensitive film unit at an exposure plane;
- and
- means responsive to said third set of signals for providing an optical image representative of said enhanced image and for projecting said enhanced image onto said exposure plane to record it on a film unit thereat.
An electronic imaging copier configured for print and transparency copying modes of operation for making enhanced photographic copies of color reflection print and transparency types of photographs, said copier comprising:
- means for supporting a print at a first object plane;
- means for supporting a transparency and being mounted for movement between an inoperative position and an operative position wherein it supports a transparency at a second object plane;
- optical means, including an objective lens mounted for movement between print and transparency imaging positions, for providing an optical image of a print, supported at said first object plane, at an image plane when said objective lens is in said print imaging position and for providing an optical image of a transparency, supported at said second object plane, at said image plane when said objective lens is in said transparency imaging position;
- photoresponsive means for sensing an optical image at said image plane and being operative to provide, in sequence, a first set of electronic image signals representative of a low resolution version of said image and a second set of electronic image signals representative of a higher resolution version of said image;
- means for presenting green, red and blue filters, in sequence, intermediate said objective lens and said image plane such that said first and second sets of signals each include green, red and blue components of said image;
- memory means for storing said first set of signals;
- display means responsive to at least said green component of said first set of signals for displaying a low resolution version of said image;
- signal processing means for selectively processing said first and second set of signals to provide a third set of signals representative of an enhanced version of said image;
- means for supporting a photosensitive color film unit at an exposure plane;
- and
- means responsive to said third set of signals for providing an optical image representative of said enhanced image and for projecting said enhanced image onto said exposure plane to record it on the film unit thereat.
