In this paper, a new adaptive frame rate upconversion algorithm is presented, and its rapid implementation method in hardware is further discussed. With inner parameters and weighted block-matching error, the algorithm implements adaptive motion compensation. Therefore, this algorithm can effectively reduce the noise-interference and the hardware realization complexity. By using a look-up table that corresponds to the adjustable parameter and employing FPGA, the algorithm for scan format conversion is realized. Its application in practical system shows that this algorithm is very efficient.
