摘要：
A pixel interpolation method for interpolating a pixel value of a target pixel in a target picture is disclosed. The pixel interpolation method includes performing up-sampling upon the target picture for generating an up-sampled picture corresponding to the target picture, and interpolating the target pixel according to the up-sampled picture. The step of performing up-sampling upon the target picture includes interpolating and generating a third pixel in between a first pixel and a second pixel that are a pair of two adjacent pixels of each pixel line of the target picture, whereof a pixel value of the third pixel is an average of pixel values of the first pixel and the second pixel.
