Abstract: An image processing method for processing an interleaved image is disclosed. A reference window and direction windows matched to the reference window are set with respect to known pixel rows in the interleaved image. First parameters along candidate directions of the reference window is calculated, wherein the first parameters denote pixel differences between the reference window and the direction windows. A respective first direction, among direction groups of the candidate directions and corresponding to a minimum of the first parameters, is found. First and/or second portion direction of first and second portions of the interleaved image are found among the first directions. The first and the second portions of the interleaved image are identified according to the first parameters. A center pixel of the reference window is obtained by interpolation according to the first and the second portion directions.
