Abstract
A method and a system for determining a video deinterlacing strategy are disclosed. First, all the pixels of a (i+2)th field are subtracted from the corresponding pixels of the ith field to obtain a difference field. Next, a specific check-area is located according to the difference field. Next, the ith field is combined with the (i+1)th field into a specific frame. Next, the combing phenomenon of the specific check-area in the specific frame is checked to determine the deinterlacing scheme for the pixels in the specific check-area.
