摘要
It is sought to provide a motion vector post-processor, which can improve motion vectors of blocks containing boundaries of objects in different movements to provide as visually satisfactory interpolated field quality as possible. Motion vectors generated in a motion estimator are stored in a memory, and their magnitudes are calculated in a magnitude calculator. Magnitude data is fed to an order statistics filter. The filter detects the serial number of a motion vector (for instance third motion vector) less than a magnitude at the center among a plurality of (for instance nine) input motion vectors and outputs corresponding serial number data to the memory. The memory outputs the vector corresponding to the input serial number data to a field interpolator. According to the invention, it is possible to provide a motion vector of an area containing small movement as motion vector of a block containing mixed movements.
