Abstract
Image interpolation methods for interpolating a destination pixel of a destination image by using a plurality of source pixels of a source image are provided. The method includes the steps of: selecting the plurality of source pixels from the source image corresponding to the destination pixel; obtaining a gradient direction and a gradient magnitude according to the plurality o source pixels; determining a weight corresponding to each of the plurality of source pixels according to the gradient direction and the gradient magnitude; and performing an interpolation operation according to pixel values of the plurality of source pixels and the weight corresponding to each of the plurality of source pixels to obtain a pixel value of the destination pixel.
