Claim Text:
1. A method for generating a predicted value of an image comprising: determining a searching scope based on known motion vectors around the current block, wherein the searching scope represents searched set of known motion vectors neighboring the current block; wherein determining a searching scope comprises obtaining a candidate motion vector set of the current block as the searching scope; performing up-sampling interpolations on first reference blocks by using a first filter to obtain up-sampled first reference blocks, wherein the first reference blocks comprise reference blocks in a reference image of a current block corresponding to the motion vector in the searching scope, and wherein the reference images are reconstructed images around the image to which the current block belongs; performing up-sampling interpolations on second reference blocks by using a second filter to obtain up-sampled second reference blocks, wherein the second reference blocks comprise reference blocks in the reference image of the current block corresponding to the at least one candidate motion vector; and combining the up-sampled second reference blocks to generate a predicted value of the current block during image encoding or decoding, wherein the predicted value is an average value of the up-sampled second reference blocks pointed by the candidate motion vector which is determined by the up-sampled first reference blocks.
