ABSTRACT
Today, digital cameras are ubiquitous. One can be purchased for a price equivalent to a night’s stay in a hotel in occidental countries, or it may be included for “free” in a mobile phone or a laptop computer. The existence of such a common and ultimately cheap device is due to fundamental developments in the way an image is acquired by the sensor and processed by the microcomputer embedded in the camera. These developments would not have been possible without recent breakthroughs in digital color image processing [1].
