Abstract: An apparatus to suppress artifacts in an image signal. The apparatus includes a differential value calculation unit to calculate a differential value between adjacent pixels with respect to an input image signal, a diffusion amount calculation unit to calculate an amount of diffusion between the adjacent pixels on the basis of the differential value calculated by the differential value calculation unit, and a pixel value conversion unit to convert the present pixel value of the image signal inputted on the basis of the diffusion amount between the pixels calculated by the diffusion amount calculation unit. The apparatus changes the pixel value in consideration of the differential value between the adjacent pixels, and thus it can provide a high quality image signal without losing or misrecognizing the artifacts of the image signal.

Abstract: An adaptive motion estimation apparatus and method. A full search motion estimation part obtains a motion vector from all blocks in a predetermined search range based on a current frame and/or field and a reference frame and/or field and a prediction motion estimation part estimates a motion vector from ambient blocks about a block in which a candidate motion vector is estimated. A motion vector selection part determines a motion vector having a position value of a smallest error in comparison with a stored threshold value among the obtained and estimated motion vectors as a final motion vector. Since the full search motion estimation algorithm and the prediction motion estimation algorithm are adaptively selected, a smooth and correct motion vector reflecting an actual motion is obtainable.
