Method for operating a camera/monitor system for a motor vehicle which is a truck with a tractor and a trailer, in which the camera/monitor system comprises a camera assigned to a longitudinal side of the motor vehicle and designed to provide an image of a surround of the motor vehicle, comprising: - specifying a region of interest in the surround, the specification of the region of interest comprising a determination of a specified image content and/or a determination of vehicle data and/or a specification by means of an input device, - transforming the image of the camera into a transformed image such that the region of interest is arranged in a specified image region in the transformed image, wherein the specified image region has a specified magnification, and the region of interest is depicted in the transformed image with unchanging magnification, independently of a change in the position of the region of interest in the surround, and wherein the image is transformed such that specified regions of the surround are depicted with different magnifications in specified image regions in the transformed image, wherein the respective positions of the image regions are changed in the transformed image on the basis of the change of the position of the region of interest in the surround, wherein, in the case of a significant articulation angle between the tractor and the trailer, the surround in the transformed image is compressed significantly in an image region in which a trailer rear edge is depicted so that the trailer takes up as little space as possible in the overall region, and the image region, in which the region of interest is arranged and which is adjacent to the image region in which the trailer rear edge is depicted, can consequently represent the surround with the conventional magnification without the trailer being depicted in the image region in which the region of interest is arranged and/or without the image of the trailer taking up too much space in the image region in which the region of interest is arranged, wherein the region of interest is always depicted in the specified image region. - specifying a region of interest in the surround, the specification of the region of interest comprising a determination of a specified image content and/or a determination of vehicle data and/or a specification by means of an input device, - transforming the image of the camera into a transformed image such that the region of interest is arranged in a specified image region in the transformed image, wherein the specified image region has a specified magnification, and the region of interest is depicted in the transformed image with unchanging magnification, independently of a change in the position of the region of interest in the surround, and wherein the image is transformed such that specified regions of the surround are depicted with different magnifications in specified image regions in the transformed image, wherein the respective positions of the image regions are changed in the transformed image on the basis of the change of the position of the region of interest in the surround, wherein, in the case of a significant articulation angle between the tractor and the trailer, the surround in the transformed image is compressed significantly in an image region in which a trailer rear edge is depicted so that the trailer takes up as little space as possible in the overall region, and the image region, in which the region of interest is arranged and which is adjacent to the image region in which the trailer rear edge is depicted, can consequently represent the surround with the conventional magnification without the trailer being depicted in the image region in which the region of interest is arranged and/or without the image of the trailer taking up too much space in the image region in which the region of interest is arranged, wherein the region of interest is always depicted in the specified image region.
