11. An estimation method of a predicted motion vector for an image block having one or more pixels, the estimation method comprising:
-
detecting a current pixel value corresponding to a current frame and a reference pixel value corresponding to a reference frame for each pixel of the image block; and calculating a difference value between the current pixel value and the reference pixel value as the pixel difference value; comparing the pixel difference value of each pixel with a variation threshold value to generate a comparison result; and selecting pixels having pixel difference values greater than the variation threshold value to form the pixel difference area according to the comparison result; and determining a predicted motion vector according to the pixel difference area. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
