Patent ID: 7894520

Claim:
A method of operating a frame rate conversion system including a computation device to perform a frame rate conversion, the method comprising: ascertaining a frame rate of a source material; ascertaining a frame rate of a display format; performing a frame rate conversion of the source material into the frame rate of the display format to calculate at least one intermediate frame; and providing for display both frames of the source material and the at least one intermediate frame; wherein said performing a frame rate conversion includes: arranging forward-motion vectors and backward-motion vectors in an alternating interleaving pattern such that a ratio of a maximum distance between two vertically or horizontally adjacent forward samples of the motion vectors and a distance between two diagonally adjacent forward samples of the motion vectors is two divided by the square root of two, wherein a horizontal and vertical distance between two adjacent samples of the forward- and backward-motion vectors is one; and calculating an intermediate frame using the alternating interleaving pattern; wherein a total number of forward-motion and backward-motion vectors in the alternating interleaving pattern is the same as a full-resolution forward-only or backward-only vector scheme; and wherein the alternating interleaving pattern provides a higher vector resolution for a specified direction than would a horizontal-only interleaving or a vertical-only interleaving pattern.
