Abstract
The present disclosure relates to an image scaling method and an apparatus thereof. The method includes: for at least one interpolation pixel in a source image, grouping at least two adjacent pixels of the interpolation pixel to obtain adjacent pixel sets; no intersection existing between the adjacent pixel sets; determining, based on position relationships between the interpolation pixel and regions formed by the adjacent pixel sets, virtual interpolation pixels corresponding to the interpolation pixel in the regions formed by the adjacent pixel sets respectively; calculating corresponding pixel sampling values of the virtual interpolation pixels in the source image according to a preset bilinear interpolation algorithm respectively; and generating theoretical pixel values corresponding to the interpolation pixel based on the pixel sampling values corresponding to the virtual interpolation pixels; the theoretical pixel values being configured to perform image scaling on the source image. The processing efficiency of the image scaling can be improved with the method.
