A camera system for producing super resolution images, the camera system comprising: a lens (106, 108); a detector array configured to capture images of a scene focused through the lens (106, 108) onto a focal plane, the detector array comprising an array of individual detectors configured to provide pixels for respective portions of the scene, the detector array being configured to capture the images in increments in each of which the lens (106, 108) or the detector array and thereby the focal plane is moved a length of an individual detector along a horizontal direction or a vertical direction as defined by a physical arrangement of the detector array; and a processing unit configured to determine light intensities of the pixels in the images, and calibrate the pixels to a reference pixel of the pixels based on the light intensities and thereby compensate for any differences in sensitivity of the individual detectors, characterized in that: for each pixel of at least some of the pixels, the processing unit being configured to calibrate the pixel includes being configured to at least: perform a comparison of a light intensity of the reference pixel of one of the images and a light intensity of the pixel in 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 pixel in the other of the images; and based thereon, determine a first multiplier for adjustment of the light intensity of the pixel at least in an instance in which the light intensity of the reference pixel in the one of the images and the light intensity of the pixel in the other of the images are different, the first multiplier for adjustment being or being determined from a first ratio of the light intensity of the reference pixel in the one of the images to the light intensity of the pixel in the other of the images. a lens (106, 108); a detector array configured to capture images of a scene focused through the lens (106, 108) onto a focal plane, the detector array comprising an array of individual detectors configured to provide pixels for respective portions of the scene, the detector array being configured to capture the images in increments in each of which the lens (106, 108) or the detector array and thereby the focal plane is moved a length of an individual detector along a horizontal direction or a vertical direction as defined by a physical arrangement of the detector array; and a processing unit configured to determine light intensities of the pixels in the images, and calibrate the pixels to a reference pixel of the pixels based on the light intensities and thereby compensate for any differences in sensitivity of the individual detectors, characterized in that: for each pixel of at least some of the pixels, the processing unit being configured to calibrate the pixel includes being configured to at least: perform a comparison of a light intensity of the reference pixel of one of the images and a light intensity of the pixel in 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 pixel in the other of the images; and based thereon, determine a first multiplier for adjustment of the light intensity of the pixel at least in an instance in which the light intensity of the reference pixel in the one of the images and the light intensity of the pixel in the other of the images are different, the first multiplier for adjustment being or being determined from a first ratio of the light intensity of the reference pixel in the one of the images to the light intensity of the pixel in the other of the images. for each pixel of at least some of the pixels, the processing unit being configured to calibrate the pixel includes being configured to at least: perform a comparison of a light intensity of the reference pixel of one of the images and a light intensity of the pixel in 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 pixel in the other of the images; and based thereon, determine a first multiplier for adjustment of the light intensity of the pixel at least in an instance in which the light intensity of the reference pixel in the one of the images and the light intensity of the pixel in the other of the images are different, the first multiplier for adjustment being or being determined from a first ratio of the light intensity of the reference pixel in the one of the images to the light intensity of the pixel in the other of the images.
