FIELD: optical electronic systems for creating and processing infrared images, in which it is needed to remove irregularities of signals, appearing due to differences in sensitivity to input stream and in dark current of elements of photo-receiving devices.
SUBSTANCE: in accordance to method, as source of information for determining correcting coefficients, signals of changing scene are used, on basis of which firstly ratios of sensitivities are determined and relative shifts of all pairs of neighboring photo-receiving device, and at second stage on basis of ratios of sensitivities and relative shifts correcting coefficients are on basis of sensitivity and shift of elements.
EFFECT: eliminated irregularity of photo-receiving devices in absence of standard signal sources.
