Patent ID: 8379146

Claim:
A deinterlacing method for a digital motion picture, the method comprising the steps of: determining if a predicted pixel lies in an artificial horizontal line according to a relationship among a first pixel value, a second pixel value, a first threshold value and a second threshold, the first pixel and the second pixel respectively lying in a first field and a second field which are in an interlace relationship and in adjacent temporal sequences, and the first threshold value being greater than the second threshold value, wherein when an absolute value of a difference between the first pixel value and the second pixel value is greater than the first threshold value or less than the second threshold value, the predicted pixel is determined to lie in the artificial horizontal line; and computing a luminance value of the predicted pixel in a still manner if the predicted pixel is determined to lie in the artificial horizontal line, wherein the predicted pixel lies in a predicted field which is combined with the second field to form a new non-interlaced frame, and wherein the first pixel, the second pixel and the predicted pixel all have the same field coordinates.
