Abstract: The upsampling of a single frame is realized by means of FFT. The realizing strategy is improved, i.e., the block-based treatment of full images is adopted so as to raise the implementing efficiency of the algorithm. The efficiency of the block-based treatment is compared with that of the full-image treatment.

Key words: upsampling, interpolation, superresolution
