ABSTRACT:
An interfield interpolating apparatus performs vertical and horizontal motion compensation by a high-speed memory device having an FIFO structure. By applying and varying vertical motion vector data to the FIFO memory device, scanning lines are delayed by as much as the varied amount to perform vertical motion compensation. Simultaneously, horizontal motion vector data is varied and applied, thereby pixels are delays by as much as an even number unit of the varied amount in the FIFO memory device, and the remaining varied amount is compensated in a one-pixel unit delay circuit. To fulfill the horizontal and vertical motion compensations, the apparatus also includes a motion-compensating unit, with a field delay circuit in which the output data of a delay circuit is delayed by as much as predetermined scanning lines and pixels in accordance with vertical and horizontal motion vector data.
