Abstract
An image interpolation method obtains an image line pixel value between two adjacent image lines. The method acquires a luminance change of pixels of two image lines and decides a region of two image lines where only one portion similar to a part of the luminance change of one of the image lines exists in the luminance change of the other image line in the vicinity of the image to be interpolated. Then, among pixel sets located at the symmetric positions about the object image to be interpolated with respect to the pixel within the region, the set having the highest similarity is selected. By using the pixel value of the selected set, the pixel value of the pixel to be interpolated is decided.
