Abstract
The invention relates to a procedure for mapping when capturing video streams by means of a camera, such as an IR camera, as well as to a computer program and a computer program product. According to the procedure the following items are included: a) at least two reference images are recorded in production against a black-body radiator at the same temperature for two or more separate integration times (block), b) in conjunction with the updating of an offset map, details of the integration time for which the offset map has been updated are stored (block), c) during operation, the actual integration time is compared with the integration time for the most recent updating of the offset map (block), d) the recorded reference image which lies closest to the actual integration time is selected as a reference (block), and e) a compensation per pixel for the change in the integration time is calculated by linear interpolation between the selected reference image and the most recently updated offset map, resulting in a compensation map (block). The integration time can be adapted dynamically by the procedure with access to adequate maps for correction of the offset of constituent pixels.
