FIELD: two-dimensional television follow-up system.
SUBSTANCE: the method for measurement of mismatching is based on plotting of a differential correlation function, where the modules of the values of the differential correlation functions in each channel are increased by the error value, the device has a video amplifier, threshold device, standard-pulse generator, delay line, control unit, recording unit standard image memory unit from the first to the fifth multiplies, from the first to the sixth low-pass filters, the first and second multipliers with an automatic gain control, the first and second subtracters, function generator σ, as well as the first and second function generators K*diff.
EFFECT: eliminated error arising at a joint operation of the channels of the follow-up system.
