Abstract
An frame rate up-conversion (FRC) apparatus and method are provided. The motion vector generating circuit compares a previous original frame with a current original frame to obtain the first motion vectors of the blocks of the current original frame, and compares the current original frame and a posterior original frame to obtain the second motion vectors of the blocks of the current original frame. The motion vector correction circuit checks whether the blocks of the second original frame are located in an occlusion area, and corrects the motion vectors of the blocks in the occlusion area based on the first motion vectors and the second motion vectors of the first original frame, the second original frame and the third original frame. The interpolation frame generating circuit creates at least one interpolation frame between the first original frame and the second original frame based on the corrected motion vectors.
