A method of producing super resolution images includes a detector array capturing images of a scene in which detector array provides pixels for respective portions of the scene, and the detector array captures the images in increments in each of which a lens or the detector array is moved a length of an individual detector. The method also includes a processing unit determining light intensities of the pixels, and calibrating the pixels to a reference pixel based on the light intensities and thereby compensate for any differences in sensitivity of the individual detectors. This calibration is based on a comparison of light intensities of the reference pixel and an other pixel in respectively one and an other of the images in which the portion of the scene is the same for the reference pixel in the one of the images and the other pixel in the other of the images.
