Conversion method of the frame frequency of a video signal from 50 Hz to 75 Hz with movement compensation and apparatus for implementing such method

摘要

A method is described for the conversion of the frame frequency of a video signal of progressive scansion from 50 Hz to 75 Hz; the main characteristic of the method consists in the fact that a temporal redistribution of the original frames is provided and an interpolation of an additional frame every two originals.;A second important characteristic of the described method consists in the fact that the interpolation provides a movement compensation; a movement vector is associated to every pixel of the frame to be interpolated; the values of the interpolated pixels are produced with an operation of average along the estimated path of movement.
