Abstract

A method for determining and assigning colorimetry and authorship device information to an image of unknown colorimetry includes iteratively displaying the image on a display device and selecting possible source device profiles for transforming the image. When a possible source device is indicated or selected, the source device is emulated on the display device and the image is displayed through the emulation. A user can then evaluate the indicated source device and if necessary indicate a new possible source device. When the most likely source device is selected, further image processing is enabled. The method can be carried out on a color image processor comprising a source device emulator and display device interface. The display device interface can use a display device profile for profile connection space to display device transformation.
