METHOD OF AND APPARATUS FOR PROCESSING IMAGES

摘要

A method suitable for processing a digital image is disclosed. The method comprises, for each picture element of the digital image, processing an achromatic intensity level of the picture element using a first adaptation procedure featuring a first effective saturation function of the achromatic intensity, to provide a first intermediate intensity level. The method further comprises processing the achromatic intensity level using a second adaptation procedure featuring a second effective saturation function of the achromatic intensity, to provide a second intermediate intensity level. The method further comprises combining the first and the second intermediate intensity levels to provide a new achromatic intensity level associated with the picture-element.
