Abstract
An image scaling method for calculating a pixel value of a target pixel within a scaled image block is disclosed. The method includes selecting a plurality of reference pixels from the image block, wherein each reference pixel has a pixel value and corresponds to a transparency parameter; respectively setting a corresponding weight value for each reference pixel; adjusting the weight values according to the transparency parameters of the reference pixels; and blending the pixel values of the reference pixels to generate the pixel value of the target pixel according to the adjusted weight values of the reference pixels.
