摘要： A method for correction of non-uniformity in signal level in different image points in an IR-camera, based on a scene being observed during movement in time of detector elements, of a camera in which the detector elements are arranged and/or of the scene, with deviating output signals for the same energy in the scene measured by different detector elements being corrected for image interference so that they provide essentially the same output signal. Micro-mechanical gyros are introduced that measure the angular velocity parallel to and perpendicular to the optical axis of the scene. The measured movement is used as an estimate for calculating the movement with a movement estimation method based on scene data. The estimated movement is coordinated with an associated image. The difference between the most recent image and the immediately preceding image or the average value of a plurality of preceding images is calculated as offset parameters. The offset parameters are updated by correction of previous offset parameters with the most recent offset parameters. The most recent image is corrected for static noise by applying the most recently produced offset parameters to the most recent image.
