METHOD OF CORRECTION OF HETEROGENEITY OF MATRIX PHOTOINTAKES WITH MICROSCANNING Russian patent published in 2009 - IPC H04N5/33 

FIELD: physics, a photo.

SUBSTANCE: invention concerns optic-electronic systems of formation and processing of infrared images for which the problem of elimination of heterogeneity of the signals caused by distinctions in sensitivity to an input stream and in the dark current of the photointake devices (PID) is actual, with use only scene signals. The technical effect is reached by that readout of the PID devices on scene signals register, on readout spot correcting coefficients on bias and sensitivity, correct scene readout. For pinch of accuracy of correcting coefficients change scene readout in microscanning directions.

EFFECT: correction on signals of a scene of heterogeneity of matrix multielement photointakes for images with the high spatial resolution, gained by means of microscanning with detrusion of a photointake of the image of a scene impinging on a matrix on half-pixel on a trajectory upwards-to the right-downwards-to the left.
