ABSTRACT:
An apparatus and method for converting an interlaced image into a progressive image, the apparatus includes a motion detector which detects motion at an object pixel of the interlaced field image, using proceeding and following field images; an interpolation direction determination unit which determines a direction in which the object pixel is to be interpolated, using values of pixels along scan lines where the object pixel is not located when motion at the object pixel is detected; a first interpolator which spatially interpolates the object pixel according to the determined direction; and a second interpolator which resets a value of the object pixel using corresponding values of pixels of the preceding and following field images and a value obtained by spatially interpolating the object pixel when the object pixel contains high-frequency components in the vertical direction.
