In this paper, Sobel operator detected around the point to be interpolated pixel of the original image pixel to determine whether the detected edge point and the edge direction, and then based on the pixels along the edge to smooth gray change, on both sides of the edge pixel gray value mutation the conduct to be interpolated pixel adaptive interpolation. The algorithm has lower computational complexity of the objective good quality, best visual effects and image scaling overall performance. This work is being developed for digital TV SoC chip image post-processing part, the next step is: complete hardware implementation of the algorithm, as a SoC chip image scaling module, the module with noise reduction, de-interlacing, and other modules IP module together to form a complete digital television image post-processing SoC chip.
