ABSTRACT:
A method of image processing for transforming an input image with a first resolution into an output image with a second resolution is provided. The input image is defined with a plurality of input pixels, and the output image is defined with a plurality of output pixels. The method includes the steps of interpolating pixel values of the plurality of input pixels based on a contrast coefficient, gathering a first group and a second group of input pixels from the plurality of input pixels, corresponding to an output pixel, based on a scale between the first and second resolutions, wherein a displayed area distributed by the first group of input pixels interlaces a displayed area distributed by the output pixel but a displayed area distributed by the second group of input pixels is separated away from the displayed area of the output pixel, generating a plurality of control coefficients, and determining a value of the output pixel based on the plurality of control coefficients, the first group of input pixels and the second group of input pixels.
