Abstract
A motion compensated interpolation filter calculates an interpolated frame between two input frames of video signals having moving objects therein. The interpolation filter includes two 2-dimensional filter which are identical in structure. Each of the 2-dimensional filters has a 2-dimensional systolic array structure for providing a weighted sum of 4 pixels of each of the input frames, respectively. Each of the 2-dimensional filter includes (2N+1).multidot.(2N+1) identical processing elements, and each of a block of (2N+1).multidot.(2N+1) pixels is inputted to each of the processing elements, and each of the processing elements generates filter coefficients, to be multiplied to a corresponding pixel values. Since the systolic array structure inherently incorporates modularity and regularity therein, the interpolation filter is suitable for real-time processing with easy hardware implementation.
