ABSTRACT:
A pixel interpolation method for interpolating pixel values of a plurality of target positions of a target picture is disclosed. The pixel interpolation method includes: dynamically setting a plurality of edge detection ranges corresponding to the plurality of target positions, respectively; and for each of the plurality of target positions, performing a edge detection according to a corresponding edge detection range to determine an edge direction for the target position, and interpolating a pixel value for the target position according to pixel data corresponding to the edge direction.
