Usage of digital cameras is spreading widely as they are easy image input devices. The increasing popularity of digital cameras has provided motivation to improve all elements of the digital photography signal chain. To lower cost, digital color cameras typically use a single image detector. Color imaging with a single detector requires the use of a Color Filter Array (CFA) which covers the detector array. In this arrangement each pixel in the detector samples the intensity of just one of the many-color separations. The recovery of full-color images from a CFA-based detector requires a method of calculating values of the other color separations at each pixel. These methods are commonly referred as color interpolation or color demosaicing algorithms.
