IMAGE PROCESSING APPARATUS USING FRAME-RATE CONVERSION AND METHOD THEREFOR

摘要

PURPOSE: An image processing apparatus using frame-rate conversion and a method therefor are provided to remove a motion vector discrimination error by inter-field interval difference and perform the frame-rate conversion. CONSTITUTION: The first and second image block extracting units(210,220) extract blocks with a certain size from an inputted field-unit interface image. A motion vector extracting unit(240) compares the blocks extracted from successively inputted two images, and calculates a motion vector. A motion filter(260) discriminates whether motion exists using a motion vector value of pixels within a certain range. If the motion exists, the motion filter(260) passes the motion vector value. If the motion does not exist, the motion filter(260) compulsorily changes the motion vector to '0' and outputs the '0'. An FRC(Frame Rate Converter)(280) performs the frame rate conversion of the motion vector values outputted from the motion filter(260), and outputs an image.
