Single-chip digital cameras use an array of broad-spectrumCharge-Coupled Devices (CCD) overlayed witha colour filter array. The filter layer consists of transparentpatches of red, green and blue, such that each CCDpixel captures one of these primary colours. To reconstructa colour image at the full CCD resolution, the missing'primary values have to be interpolated from nearby samples.We present an effective colour interpolation using asimple pixel level data-dependent triangulation. This interpolationtechnique is applied to the commonly-used BayerColour Filter Array pattern. Results show that the proposedmethod gives superior reconstruction quality, with smallervisual defects than other methods. Furthermore, the complexityand efficiency of the proposed method is very close tosimple bilinear interpolation, making it easy to implementand fast to run.
