US Patent:

43420478, Jul 27, 1982

Filed:

Apr 30, 1980

Appl. No.:

6/145096

Inventors:

Stephen E. Niemczyk - Enfield CT
Richard G. Hubbard - Manchester CT

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

H04N 146

US Classification:

358 80

Abstract:

A color calibration procedure for use with a color raster scanner includes the steps of: identifying small areas on the source chart, or medium to be scanned, which contain only one color and assigning a color number to each area; positioning the scan head of the color raster scanner at two locations within the area identified and establishing the coordinate values for each of these two areas so as to bound by the coordinate definition the corners of a rectangular portion within the identified area; recording at each of a plurality of samples between the defined coordinates in each area the color samples resident therein; comparing the color samples of each color number obtained from each area with the samples obtained for each other color number of the other areas to determine the percentage of interference between colors and identifying the number of color samples which interfere with two or more colors as uncalibrated samples; and modifying the limits for a selected one of the spectral parameters associated with the interfering colors to minimize the percentage of uncalibrated data samples.

Abstract:

A color raster scanner includes separate optical paths including a resolution aperture for resolution imaging and a separate, larger screen aperture for large area imaging; each aperture receiving the reflected source chart image through common collection optics including a combination objective lens and collimating optics which extend the optical length to provide increased gain magnification of the sensed image into the objective image plane; the image from the collection optics being presented by relay optics which divide the image into the two separate apertures, at different gain magnification values (field stop to provide the resolution aperture with the major portion of the available light flux, the larger diameter value of the screen aperture allowing it to receive the minor portion of the available flux at a relatively consistent spectral intensity.
