An interlace noise filter which can obtain a high resolution still image from an interlace motion picture. An original image either in an even number field or in an odd number field is sampled by a sampling means (1) along only the horizontal direction of the original image. Then, it is Haar wavelets transformed. Thereafter, the gradation change of the original image is enlarged by a reconstituting means (3), while interpolating unsampled original image with sub pixel accuracy. <IMAGE> |
