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.
