1. Method for preparing NON-VIS images ( 4 ), having an improved resolution, characterized in that, during and/or before and after a random movement of a preferably hand-held camera for recording NON-VIS images ( 4 ) in a non-visible spectral range, e.g. in an IR, UV, THz and/or microwave spectral range, or during and/or before and after a random movement of a moving vehicle carrying a camera for recording NON-VIS images in a non-visible spectral range, e.g. in an IR, UV, THz and/or microwave spectral range, a NON-VIS image data stream ( 5 ) of NON-VIS images ( 4 ) is recorded with a recorded-image resolution and in that, as a result of combining ( 20 ) the recorded NON-VIS images ( 4 ), a prepared SR image ( 9 ) with an output-image resolution is generated, with the output-image resolution being greater than the recorded-image resolution.
