Abstract
Image processing apparatus comprises an input device; an output device; and a processor coupled to the input and output devices. The processor is adapted to compare the tone range of an image scanned by the input scanner and the tone range provided by the output scanner, and i. if the input tone range falls wholly within the output tone range, to cause the output device to render an absolute reproduction of the image, or ii. if the input tone range overlaps the output tone range, to cause the output device to render a reproduction of the image in which that part of the input tone range falling outside the output tone range has substantially been mapped into the output tone range, providing a pleasing appearance.
