Motion compensated frame interpolation

摘要

A method for movement-vector-aided interpolation of a picture element (pixel) (Px) of an intermediate/inter-image lying between two input images, involves selecting a first picture element (P0) assigned first image information value (L0), selecting second and third picture elements (P1;P2) for second and third image information values (L1;L2) ascertaining an interval specified by the first and second values (L0;L1) or an intervals specified by the third and fourth values (L2;L3) and then mixing the information values (L0,L1,L2,L3) and multiplying these values with appropriate first-to-fourth weighting factors (k0-k3), respectively, and adding the obtained weighted image information values so as to obtain an image information value (Lx) of the picture element (Px) of the inter-image, where the weighting factors are selected so that image information value (Lx) lies within the ascertained interval..
