Patent ID: 8811658

Claim:
An interpolation method applied to image pictures when performing de-interlacing operations, for interpolating at least one pixel into a position to be interpolated in a target image frame, the interpolation method comprising: receiving a plurality of image fields having a corresponding image object; estimating a motion speed of the image object by computing an average motion speed according to a distance between a first pixel position to which the image object located in a first image field of the plurality of image fields corresponds and a second pixel position to which the image object located in a second image field of the plurality of image fields corresponds, wherein the first pixel position is located on a different scan line than a scan line of the second pixel position; determining a pixel from the plurality of image fields according to the estimated motion speed of the image object; and interpolating, using the estimated motion speed, the pixel into the position to be interpolated in the target image frame.
