  • Patent number: 5177694
    Abstract: A method of computerized color matching for articles where articles are photographed, using a still video camera, against a set of reference colors. The photographs are stored on a diskette (34) which is read on a recorder (54). The computer (55) compares the set of reference colors against an absolute set of colors and generates a compensation factor which is applied to the photographed colors to produce a corrected photograph. Areas of the corrected photograph may be selected for computer enhancement and a computer generated map may be produced to enable the color of other articles to be matched to the photographed articles.
