Patent ID: 8224126

Claim:
A method for interpolating at least one subpixel at an interpolation position, said interpolation position being situated in the chronological sequence between at least two source frames, whereby said at least two source frames comprise a plurality of pixels and/or subpixels, respectively, and are correlated with each other based on at least one forward motion vector and at least one backward motion vector, said forward and backward motion vector pointing from at least one origin pixel or subpixel of the frame preceding said interpolation position to at least one target pixel or subpixel of the frame succeeding said interpolation position and vice-versa, respectively, said method comprising the steps of identifying at least one of said at least one forward motion vector and at least one of said at least one backward motion vector respectively relating to at least one subpixel at the respective same spatial coordinate at said interpolation position, determining the values of the origin and target pixels or subpixels pointed by said identified motion vectors, respectively, and calculating the value of said at least one subpixel at said spatial coordinate based on said values of origin and target pixels or subpixels of said identified motion vectors and based on respective weighting coefficients, said weighting coefficients being based on attributes of said identified motion vectors.
