Hybrid interpolation methods are provided that employ more than one interpolation algorithm and choose the most appropriate interpolation algorithm that provides high quality images with a minimum processing time. Prediction means is first applied to predict which interpolation is most appropriate for a given pixel in terms of complexity and performance. Then, a simple interpolation algorithm is used for pixels for which the simple interpolation algorithm provides acceptable performances and a complex interpolation algorithm is used for pixels for which the complex interpolation algorithm, which requires a larger number of operations, significantly outperforms the simple interpolation algorithm. Consequently, it is possible to obtain high quality images without significantly increasing the processing time.
