Title: METHOD FOR GENERATING A NOISE-REDUCED IMAGE BASED ON A NOISE MODEL OF MULTIPLE IMAGES, AS WELL AS CAMERA SYSTEM AND MOTOR VEHICLE
Abstract:
The invention relates to a method for generating a noise-reduced image (lD), in which a noisy image (lN) is captured by a camera (3) of a motor vehicle (1) and the following steps are performed: a) capturing an image sequence (10) of images (9) by the camera (3); b) determining a noise model (NLF) based on multiple images (9) of the image sequence (10); c) determining a weighting value (wxy) for weighting the noisy image (lN) as well as at least one image (lB) depending on the noisy image (lN) based on the noise model (NLF); d) generating a blurred image (lB) based on the noisy image (lN); e) generating a weighted blurred image by weighting the blurred image (lB) depending on the weighting value (wxy); f) generating a weighted noisy image by weighting the noisy image (lN) depending on the weighting value (wxy); and g) generating the noise-reduced image (lD) based on the weighted blurred image and the weighted noisy image.
