Abstract
As the resolution of the image display devices has been diversified, the image interpolation methods has played a more important role. The cubic convolution interpolation method has been widely used because it is simple but it has no limitation of using and a good performance. This paper suggests an adaptive method to the cubic convolution interpolation. Considering the difference of the neighbored pixels values to a prediction pixel, a parameter value in the cubic convolution interpolation kernel is chosen.
