Abstract: A pixel interpolation method includes: utilizing a plurality of pixel pairs on two successive scan lines to determine at least one first possible angle; utilizing a plurality of pixel value distribution trends of the two successive scan lines to determine at least one second possible angle; comparing pixel values of a plurality of pairs of neighboring pixels to detect whether the pixel values are larger than a threshold value in order to determine at least one third possible angle; determine a most appropriate angle according to the first, second, and third possible angles; detecting whether the most appropriate angle is correct by examining that the most appropriate angle is in a group; and utilizing a first pixel on the upper scan line of the two successive scan lines and a second pixel on the bottom scan line of the two successive scan lines to interpolate the a target pixel.
