摘要：We present improved practical color filter array interpolation methods that use color correlation for use in digital cameras.Cost-effective digital cameras use a single-chip image sensor and subsequent interpolation processing to produce full-color images.Therefore,many type of sophisticated algorithms have been proposed to create high quality images.Their complicated algorithms make it difficult,however,for them to be implemented in digital cameras due to limited computing capacity or available processing time.Although existing interpolation methods that use a directional color correlation are very cost-effective,they result in color artifact on the edge of color boundaries.We propose two algorithms to resolve this problem.One is a constrained color correlation method that is achieved by adding constrained conditions.The other is the precious color correlation methods that uses a nonlinear filter.The proposed methods can eliminate the artifact regardless of any color correlation of the images.Experimental results confirm the effectiveness of these methods.
