Abstract
An electronic imaging copier is provided for making enhanced photographic copies of reflection print and transparency types of photographs. The copier initially operates in a preview display mode during which the operator may view and interactively make selected modifications to an electronic image of the photograph displayed on a display screen. Thereafter, the copier operates in a copy mode to make an enhanced photographic print of the displayed image.
Claims16
An electronic imaging copier for making an enhanced photographic copy of a photograph, said copier being initially operable in an interactive preview display mode for viewing and selectively modifying an electronically displayed image of the photograph and thereafter being operable in a copying mode for producing an enhanced copy, said copier comprising:
- means for supporting a photograph at an object plane;
- optical means for providing an optical image of the supported photograph at an image plane;
- photoresponsive means for sensing an image provided at said image plane and being selectively operable 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 image signals;
- display means responsive to at least a portion of said first set of signals for displaying a low resolution version of said image;
- first signal processing means being selectively operable during said preview display mode and responsive to operator actuable input signals for processing said portion of said first set of signals provided to said display means to modify selected image defining parameters and, if modifications are made during said preview display mode, being operative during said copy mode for processing subsequent signals in said first and second sets to apply said selected modifications thereto;
- second signal processing means for processing said first and second set of image signals, subsequent to any modifications by said first signal processing means, 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 for making enhanced photographic copies of reflection print and transparency types of photographs, said copier being initially operable in an interactive preview display mode for viewing and selectively modifying an electronically displayed image of the photograph and thereafter being operable in a copying mode for producing an enhanced copy, said copier comprising;
- 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 a print copying mode for providing an optical image of a supported print at an image plane, and in a 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 display set of electronic image signals representative of a low resolution version of said image, a first set of copy image signals representative of a low resolution version of said image, and a second set of copy image signals representative of a higher resolution version of said image;
- memory means for storing said display set and said first and second sets of copy image signals;
- display means responsive to said display set of signals for displaying a low resolution version of said image;
- first signal processing means being selectively operable during said preview display mode and responsive to operator actuable input signals for processing said display set of signals to modify selected image defining parameters and, if modifications are made during said display mode, being operative during said copying mode for applying said selected modification to said first and second sets of copy signals;
- second signal processing means for processing said first and second sets of copy signals, whether modified or not, to provide a third set of copy 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 copy 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.
