  • Cameras for capturing partial image sections include that the partial image sections of the two cameras arranged next to one another overlap and that the output device is set up to merge all of the partial image sections. With this arrangement, additional image content is available without covered areas, which increases the information content of the merged image. In addition, camera optics with longer focal lengths can be used, which reduces the effort required to avoid distortion errors.
