ABSTRACT:
A method of collecting the spactial positions of crossing points of the lines in the grid on the visible portion of the screen of a television receiver used in different modes of operation includes the steps of storing a first set of correction values for each of the crossing points. The first correction values define the spactial positions of the correction points for all modes of operation of the television receiver. Additional correction values are stored for each mode of operation. The additional correction values are generated during an overscan period and during the scanning of an initialization line which is positioned outside the visible portion of the screen and compensate for displacement of the crossing points induced by tolerances in the tube. The first correction values and the additional correction values are simultaneously applied to the deflection current of the television tube while the visible portion of the screen is scanned.
