1. An image processing apparatus using a judder-map, the apparatus comprising: a field storage block to receive an input interlaced video signal including an input image having a plurality of consecutive fields; a film detecting block to receive the plurality of consecutive fields from the field storage block and to determine whether the input image is an image in a film mode; a judder-map generating block to detect judder created on a pixel or block of neighboring fields among the plurality of consecutive fields provided from the field storage block and to generate a judder-map based on the detected judder; and an image interpolating block to perform image interpolation using the judder-map if the input image is determined to be an image in the film mode, and to generate and output a resultant progressive video signal.
