ABSTRACT:
A method of image scaling includes the steps of: determining the coordinates of a virtual pixel in an original image, wherein the virtual pixel corresponds to an actual pixel in a scaled image; determining the coordinates of four actual pixels in the original image that are closest to the virtual pixel; determining the weights of the four actual pixels; and determining the pixel value of the virtual pixel in the original image in accordance with the determined weights and the pixel values of the four actual pixels.
