Abstract (en)

[origin: WO2006088641A1] In a system and a method for profiling a digital-image input device, profiling of the digital-image input device is performed based at least on an image of a color chart and an estimated illumination of the color chart generated by comparing illumination of device-dependent coordinate values for the image of the color chart with illumination of device-independent coordinate values of the color chart. Because the estimated illumination of the color chart is performed on data pertaining to the color chart, the present invention may generate a profile without reference to data pertaining to scenery in the image outside of the color chart. Consequently, the present invention may generate a profile irrespective of the relative exposure of the color chart with respect to other scenery in the image.
