In this paper, we propose a color interpolation method using high order B-splines for a single-chip CCD (charge-coupled device). Single-chip digital cameras use a color filter array (CFA) and an interpolation method in order to reconstruct high quality images from sparsely sampled images. Frequently, single-chip digital cameras use the bilinear interpolation method due to the simple implementation and fast processing time. In this paper, we have applied the interpolation algorithm using the cubic spline in order to obtain high quality images. Experiments show that the cubic spline interpolation method provides better performances than the bilinear interpolation method.
