摘要：The present invention provides an image decoder which decodes a streamencoded with standard resolution and transforms it into a high-definition image with abetter image quality. An intra-field pixel interpolation module generates an interpolatedpixel using pixels in a field. An inter-field pixel interpolation module generates an

interpolated pixel using pixels from another field. A weighted averaging module refers tothe prediction mode used in predictive encoding for the coded stream. If the predictionmode is a field prediction mode, it increases the mixture ratio of interpolated pixelsgenerated by the intra-field pixel interpolation module, and if the prediction mode is aframe prediction mode, increases the mixture ratio of interpolated pixels generated bythe inter-field pixel interpolation module.
