摘要： A method and apparatus for creating a digital image on photographic paper and subsequent correction of color. The method and apparatus provides a digital image printer that is capable of rapidly producing digital images on photographic paper having good clarity and sharpness and correct color content. Further, the method and apparatus provides a digital image printer having a controllable lamp house that is easily removable and may be coupled with conventional photographic printers. The apparatus is a digital printer having a central processor for retrieving digital images stored on a file and for creating an inverted image of the digital images, a projecting means controller that is electrically connected to the central processor, an imaging means that is electrically connected to the projecting means controller for creating and transmitting a color corrected image, a lamp house that is positioned adjacent the imaging means for creating an optical signal and modulating the spectral content of the optical signal, a spectral content analyzer that is attached to the lamp house, a lamp house controller coupled to the lamp house, a lens system for focusing the color corrected image onto photographic paper, and a paper drive means having a supply and take-up for providing and advancing photographic paper.

摘要： This invention relates to the printing of color photographs onto photographic paper from color negatives, and more particularly to a method and apparatus for analyzing the color correction values necessary to achieve printing of such negatives in such a way as to produce a finished print having acceptable color rendition. A method and apparatus are contemplated by which an operator may directly view a color image of a negative from which printing is to occur and directly observe the effects on printing of variations in the spectral content of light to be used for printing. By determining the specific spectral response of a lot of printing paper, a standard correction may be established which will significantly reduce the need for trial by error correction of the printing process, effecting a saving in materials and supplies as well as in time.
