Abstract
The present invention relates, in general, to an apparatus and method for converting interlaced field image data into progressive image data in image processing techniques and, more particularly, to an apparatus and method for performing intra-field interpolation for a de-interlacer, which calculates a direction in which pixel values are changed using the variations and correlations between the pixel values of the regions on two lines in one field, and outputs an interpolated value depending on the direction, thus enabling a field to be interpolated in the change direction.
