Abstract
A scanner has a sensor assembly having a sensor to receive light from an image, and which assembly generates an image signal corresponding to the image, which image signal has a plurality of color channel components representative of different spectral regions. A media holder holds a media carrying the image. An illuminator to illuminate the image of a held media such that light from the image falls on the sensor. The illuminator has a plurality of sets of light emitting elements to provide illumination in all of the spectral regions, each set having a different spectral output with at least a first set having plural sub-sets of different spectral output within a first one of the spectral region represented by the color channels, the number of different spectral output elements being greater than the number of color channels. The illuminator also has an integrator between the array and the media holder so as to improve uniformity of the illumination from the illuminator which illuminates the image. A method of calibrating a scanner, and a method of scanning images using a scanner are also provided.
