FIELD: physics.
SUBSTANCE: invention relates to devices for capturing images in the infrared spectrum. Result is achieved by receiving a first input image (RAW) and correcting a first input image by applying gain and offset values; detecting, in the corrected first input image, at least one parasite pixel and adding said at least one parasite pixel to a parasite pixel list (LSPUR); receiving a second input image (RAW) and correcting a second input image by applying gain and offset values; and calculating amplification and offset correction values (sOff, sGain) for said at least one parasite pixel based on the first and second corrected input images.
EFFECT: technical result is performing correction of parasite pixels of a pixel matrix in an image capture device which is sensitive to infrared radiation.
