E.Kieale -2 Abstract In color-picture tubes, a maximum of three photode- tectors disposed behind the slit of a diaphragm in front of the screen center are used to determine deviations from color purity by measuring the lumi- nance distribution, and deviations from convergence by measuring the time sequence of the phosphor- stripe illuminations. By means of magnetizing cur- rents in suitable deflection means, the measured deviations are compensated for. The strengths and directions of the compensating currents determine the magnitude and direction of the correction. With this method, the measurement of deviations for performing corresponding adjustments can be auto- mated at low cost.
