Patent ID: 8325271

Claim:
A method of frame interpolation for frame rate up-conversion, comprising: determining a first adjusting value and a second adjusting value according to a target pixel in a first frame and a second frame; determining an interpolated pixel value of the target pixel in an interpolated frame between the first frame and the second frame according to the first adjusting value and a pixel value of the target pixel in the first and second frames, wherein the interpolated pixel value of the target pixel is calculated according to the equation V i — 1 =V c — 1 +(V c — 1 −V p — 1 )*r i — 1 where V i — 1 represents the interpolated pixel value of the target pixel, V c — 1 represents the pixel value of the target pixel in the second frame, V p — 1 represents the pixel value of the target pixel in the first frame, r i — 1 represents a first scaling factor, and the first adjusting value is equal to (V c — 1 −V p — 1 )*r i — 1 and adjusting a pixel value of the target pixel in the second frame according to the second adjusting value, wherein the second adjusting value is equal to (V c — 1 −V p — 1 )*r 2 — 1 where r 2 — 1 represents a second scaling factor, and the pixel value of the target pixel in the second frame is calculated according to the equation V c — 1 ′=V c — 1 −(V c — 1 −V p — 1 )*r 2 — 1 where V c — 1 ′ represents an adjusted pixel value of the second frame.
