Abstract:
1. An interpolation method for generating a target pixel at a target location within a video image, the method comprising: generating a plurality of measurement values, each of the measurement values corresponding to an edge direction and being generated according to a corresponding first pixel set and a corresponding second pixel set, wherein the first pixel set comprises at least a first pixel, the second pixel set comprises at least a second pixel, and the first pixel and the second pixel reside on opposite sides of the target location along the corresponding edge direction; identifying a minimum measurement value from the plurality of measurement values; calculating a value of the target pixel according to pixels of the first and second pixel sets which correspond to the minimum measurement value; generating a weight factor according to the minimum measurement value and at least one threshold value; and obtaining the value of the target pixel by weight-blending the first and second pixel sets corresponding to the minimum measurement value according to the weight factor.
