Abstract:
A method of determining the colorimetry of an image of unknown colorimetry with a color image processor and an associated display device, the method comprising:opening an electronic image file containing an image; indicating a preliminary source supposition for the image file; temporarily setting a currently indicated source to the indicated preliminary source supposition; transforming the image with information from a source profile associated with the currently indicated source and a display device profile of the associated display device; displaying the transformed image, thereby rendering the image as the image would appear if the currently indicated source were an actual source of the image, and evaluating the displayed image to determine if the currently indicated source should be assigned to the image indicating a new preliminary source supposition for the image if an evaluation of a prior preliminary source supposition results in a determination that the prior preliminary source supposition was incorrect, updating the currently indicated source to the new preliminary source supposition; transforming the image with information from a new source profile associated with the updated currently indicated source and the display device profile of the associated display device; displaying the transformed image, thereby rendering the image as the image would appear if the updated currently indicated source were an actual source of the image, and evaluating the displayed image to determine if the updated currently indicated source should be assigned to the image.
