Patent ID: 8553145

Claim:
An image de-interlacing method, comprising steps of: (a) defining a first threshold value and a second threshold value, wherein the second threshold value is larger than the first threshold value; (b) generating a parameter according to a motion level of a interlaced image, wherein the parameter is computed according to a difference between pixels in a vertical direction in a field of the interlaced image; (c) utilizing a first interpolation method and a second interpolation method to jointly process the interlaced image if the parameter is in a range between the first threshold value and the second threshold value; and (d) utilizing the first interpolation method to process the interlaced image if the parameter is lower than the first threshold value, and utilizing the second interpolation method to process the interlaced image if the parameter is over the second threshold value, wherein a ratio between the first interpolation method and the second interpolation method to process the interlaced image is determined according to the parameter; where the first interpolation method is utilized for processing an interlaced image with more static components, and the second interpolation method is utilized for processing an interlaced image with more dynamic components.
