ABSTRACT:
The present invention provides a method and apparatus of adaptive de-interlacing of dynamic image, in which extraction and calculation of motion vectors contained in a macro-block being processed, the value of calculation of motion vectors being then compared with a programmable threshold; wherein the macro-block being a motion block if the value of calculation being greater than the threshold and therefore Bob algorithm being chosen for de-interlacing process. Otherwise, the macro-block being a still block if the value of calculation being less than the threshold and therefore Weave algorithm being chosen for de-interlacing process. Consequently, the process is enforced continually and a dynamic image of high image quality is constituted with block as its unit.
