1. Method for preparing NON-VIS (non-visible) images for improving image resolution, comprising: at least one of during or before and after a random movement of a camera for recording NON-VIS images in a non-visible spectral range, including at least one of an IR (infrared), UV (ultraviolet), THz (terahertz), or microwave spectral range, or at least one of during or before and after a random movement of a moving vehicle carrying a camera for recording NON-VIS images in the non-visible spectral range which results in a random movement of the camera, recording a NON-VIS image data stream of the NON-VIS images with a recorded-image resolution and, as a result of combining the recorded NON-VIS images, generating a prepared SR (superresolution) image with an output-image resolution with the output-image resolution being greater than the recorded-image resolution, wherein, prior to combining the recorded NON-VIS images, establishing a transform for each of the NON-VIS images, by which the NON-VIS images are registered with sub-pixel accuracy with respect to one another or with respect to a reference, wherein, prior to combining the recorded NON-VIS images, assigning a point spread function to each of the NON-VIS images from a stored test set of the point spread functions, with the point spread functions of the test set simulating an optical imaging process of the camera for at least one of different recording directions or different recording positions, and the point spread function corresponding to the respectively established transform being assigned to each of the recorded NON-VIS images, wherein the test set stores the point spread functions which are separable, an energy function is optimized for a combination of the recorded NON-VIS images, with the energy function being evaluated on NON-VIS images tentatively combined to form an SR image, the SR image is varied during the optimization of the energy function and the point spread functions assigned to the NON-VIS images are varied during the optimization of the energy function, by displacing a center of the respective point spread function, and the registration with sub-pixel accuracy is established pixel-by-pixel and pixel values which deviate from the respectively established registration by more than a predetermined threshold are masked in the respective NON-VIS image.
