Paper Abstract

One of the important functions of DCPs on which the image quality is largely depends is color matrix calculation from the CCD's optical filter output. An algorithm which can go closer to the optimal solution for generation of color components data from CCD filter output is proposed in this paper. As far as the image quality is concerned, the best way is acquiring compete color data per pixel without any noise, and without any using an optical low pass filter. The most important role of the optical low pass filter is to scatter the ray penetrating the lens system as well as to cut below the frequency of the IR light. Basically, the proposed algorithm is non-filtered color reproduction flow. First, the proposed algorithm recovers the error made during the path of optic system in order to get better interpolation result. Then, the different procedures are adopted for green component and red or blue component interpolation based on the edge information extracted from the green image. The last procedure is edge preserving smoothing, where image data with high quality can be obtained by preserving the edge segments while smoothing the overall image.
