Claim 6:
7. The method of claim 4, wherein the step of determining pixel values of a plurality of pixels in the output image data comprises steps of:
generating a polar coordinate pixel grid of the input space for the input image data, each of the plurality of grids in the polar coordinate pixel grid of the input space corresponding to one of the pixels in the input image data;
mapping the plurality of pixels in the image corresponding to the output image data to the polar coordinate pixel grid of the input space, according to a mapping mode from the output image data to the input image data, to obtain a plurality of discrete pixels mapped;
while a pixel of the plurality of discrete pixels mapped is excluded from the pixels in the polar coordinate pixel grid of the input space, determining a neighborhood of the pixel which does not belong to the polar coordinate pixel grid of the input space, according to the polar coordinate pixel grid of the input space; performing interpolation operation on the pixel values of a plurality of pixels in the neighborhood of the pixel to obtain the pixel value of the pixel; and
obtaining the pixel values of the plurality of pixels in the output image data according to the pixel values of the plurality of discrete pixels mapped.
