Abstract:
1. Apparatus for interpolating a motion compensated picture from two source pictures, wherein, for determining the pixel value of each pixel with coordinates (x, y) of the motion compensated picture, it comprises: a first generator for computing, for each couple of motion values (mx, my), wherein the motion value mx belongs to a first range of motion values in the horizontal direction and the motion value my belongs to a second range of motion values in the vertical direction, a correlation coefficient representative of the correlation between a pixel block defined in a source picture called first source picture, around the pixel with coordinates (x−mx, y−my) and a pixel block defined in another source picture, called second source picture, around the pixel with coordinates (x+mx, y+my), a second generator for computing, for all couples of motion values (mx, my), the arithmetic mean values of the pixel value of the pixels with coordinates (x−mx, y−my) in the first source picture and the pixels with coordinates (x+mx, y+my) in the second source picture, and a fuzzy interpolation block for computing a value which is a function of the correlation coefficients computed by the first generator and the corresponding arithmetic mean values computed by the second generator.
