3IntroductionThe authors propose an effective color filter array (CFA) interpolation method for digital still cameras using a simple image model that correlates the R,G,B channels.A low-complexity interpolation method to improve the image quality.
4Color Filter Arrays -CFA ( 1/2 ) Three-CCD structure for a DSC.Single-CCD structure for a DSC.
10Proposed interpolation method ( 1/3 ) Above two methods use only the existing G channel neighborhood information to find the missing G values.There is a high correlation between the R,G,B channels.The G channel can take advantage of the R and B information.
