Patent ID: 6919970

Claim:
A method for calibrating color of an image which is transmitted from a computer image processing system A to a computer image processing system B, by transmitting a digital image in the form of scanned data based upon on an original color image directly either unmodified or after applying a color matching operation to said digital image in which operation the color of said scanned image is modified to be substantially identical to said original color image, comprising: a preparatory operation for selecting a correction value for use in applying a color matching operation before or after transmission of said scanned data, based upon a common standard color image, and a final color matching operation applied to said digital image to create a condition of substantial coincidence of a color thereof when displayed on a monitor of said system B, with a color of said original color image, by application of said correction value obtained by said preparatory operation, said preparatory operation, comprising: displaying a digital image corresponding one of said systems A and B, thereafter an initial color matching operation being applied to said digital image to create a modified digital image having substantially identical color to said common standard color image, and reading respective correction data indicated on said monitor, whereby said read correction data is determined to be said correction value.
