This reduction of flicker to the transitions of colors for the signals of the television in color and its assembly to the embodiment of the process.

摘要

In a process to reduce the flicker to the transitions of colors for a reproduction of an image of a television signal, in which a complete image is formed from two frames transmitted in succession and displayed by the interleaving method and which has a luminance signal and two colour difference signals of different types, which are transmitted individually and in each frame in alternation of a line to the other, it is provided, for the suppression of flicker to the transitions of colors, to carry out a number of comparisons of the values of image points for the image points corresponding to an image point to be reproduced, from which the conclusions can be drawn with regard to the shape of the transitions and / or of the fields of movement in the contents of the image, and to obtain the colour difference signal is not transmitted to the point of the image to be reproduced on the basis of the colour difference signal of the same type of at least one of the image points of the corresponding comparison, which is chosen in such a way that, according to the result of the comparisons between this point of the image and the corresponding image point to be reproduced, there is no transition and / or that the image point corresponding does not contribute to a movement of the contents of the image which is different from that of the image point to be reproduced.
