Patent ID: 8593709

Claim:
Scanner, comprising: an optical sensor for recording a device dependent image and for sensing device dependent print media color information; a storage device storing predetermined device independent color values of respective non-printed regions of preselected print media and storing corresponding scanner color profiles adapted for the respective preselected print media; and a processor, configured to: process device dependent color values of a non-printed region of a print medium sensed by the optical sensor; map a sensed device dependent color value of the non-printed region of the print medium through each of the scanner color profiles respectively corresponding to each of the preselected print media to generate a mapped, sensed device independent color value for each of the scanner color profiles used; compare each mapped, sensed device independent color value with the predetermined device independent color values; determine which predetermined device independent color value is closest to one of the mapped, sensed device independent color values by calculating a difference between each of the predetermined device independent color values of the non-printed regions of the preselected print media and each of the mapped, sensed device independent color values; automatically select one of the scanner color profiles based on the comparison and the determination by: selecting the scanner color profile corresponding to the predetermined device independent color value associated with a smallest difference; or selecting a default color profile when the differences are larger than a predetermined threshold; and automatically apply the selected one of the scanner color profiles to convert the device dependent image to a device independent image; wherein the non-printed regions do not have ink, toner, or another colored substance applied thereon.
