Abstract
Abstract A method is disclosed for operating a display system in a vehicle ( 01 ), having at least one camera, using which an observation region ( 02 ) in the surroundings of the vehicle ( 01 ) may be recorded, having an image processing unit, in which the image data coming from the camera may be processed, a display screen ( 05 ) inside the vehicle, on which the image data coming from the image processing unit may be displayed as an image ( 07 ), and a sensor system, using which the vehicle movement may be detected and relayed as movement data to the image processing unit. In this case, at a starting instant, a vehicle position is determined as a starting point, the vehicle ( 01 ) is moved further, beginning from the starting point, the rotational angle of the vehicle ( 01 ) around its vertical axis is detected by the sensor system, beginning from the orientation in the starting point, and the image data coming from the camera is processed in the image processing unit, taking the respective current rotational angle of the vehicle into consideration, in such a way that the orientation of objects ( 03, 04, 03 a, 04 a, 04 b, 04 c ) from the observation region ( 02 ) displayed in the image ( 07 ) on the display screen ( 05 ) corresponds to the orientation at the starting instant.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
187 words
A method of operating a display system in a vehicle having at least one camera for recording an observation region in the surroundings of the vehicle, having an image processing unit, in which the image data coming from the camera may be processed, having a display screen inside the vehicle, on which the image data coming from the image processing unit may be displayed as an image and having a sensor system for detecting the vehicle movement and relaying movement data to the image processing unit, the method comprising the steps of: at a starting instant, determining a vehicle position as a starting point; moving the vehicle from the starting point; detecting the rotational angle of the vehicle around its vertical axis using the sensor system, beginning from the orientation at the starting point; processing the image data coming from the camera in a image processing unit, taking into consideration the respective current rotational angle of the vehicle, in such a way that the orientation of objects from the observation region displayed in the image on the display screen corresponds to the orientation at the starting instant.
Claim 2
Independent Claim
187 words
A method of operating a display system in a vehicle having at least one camera for recording an observation region in the surroundings of the vehicle, having an image processing unit, in which the image data coming from the camera may be processed, having a display screen inside the vehicle, on which the image data coming from the image processing unit may be displayed as an image and having a sensor system for detecting the vehicle movement and relaying movement data to the image processing unit, the method comprising the steps of: at a starting instant, determining a vehicle position as a starting point; moving the vehicle from the starting point; detecting the rotational angle of the vehicle around its vertical axis using the sensor system, beginning from the orientation at the starting point; processing the image data coming from the camera in a image processing unit, taking into consideration the respective current rotational angle of the vehicle, in such a way that the orientation of objects from the observation region displayed in the image on the display screen corresponds to the orientation at the starting instant.
Claim 3
Dependent Claim
40 words
The method according to claim 1 , wherein the image data of multiple cameras is mixed together in the image processing unit, in order to generate a joint image from the image data to be displayed on the display screen.
Claim 4
Dependent Claim
42 words
The method according to claim 1 , wherein the camera is equipped with a wide angle lens and the image distortions caused by the wide angle lens are at least partially removed by processing the image data in the image processing unit.
Claim 5
Dependent Claim
21 words
The method according to claim 1 , wherein the observation region of the camera lies behind the rear of the vehicle.
Claim 6
Dependent Claim
37 words
The method according to claim 1 , wherein the image data is processed in the image processing unit in such a way that the image displayed on the display screen corresponds to a perspective outside the vehicle.
Claim 7
Dependent Claim
53 words
The method according to claim 1 , wherein for the display of the image on the display screen, a reduction factor is set, as a function of the rotational angle of the vehicle in relation to the starting position, for the display of the image imaging the observation region on the display screen.
Claim 8
Dependent Claim
31 words
The method according to claim 6 , wherein the reduction factor is selected in such a way that the entire observation region is shown by the image on the display screen.
Claim 9
Dependent Claim
33 words
The method according to claim 1 , wherein specific image details from the observation region may be zoomed in on during the display on the display screen by selecting a corresponding zoom factor.
Claim 10
Dependent Claim
27 words
The method according to claim 8 , wherein the position of the zoomed image detail in relation to the boundaries of the observation region may be changed.
Claim 11
Dependent Claim
26 words
The method according to claim 9 , wherein the selection of the position of the zoomed image detail is performed by a setting of the operator.
Claim 12
Dependent Claim
22 words
The method according to claim 8 , wherein the selection of the zoom factor is performed by a setting of the operator.
Claim 13
Dependent Claim
33 words
The method according to claim 9 , wherein the selection of the position of the zoomed image detail is performed automatically by the image processing unit as a function of other state parameters.
Claim 14
Dependent Claim
29 words
The method according to claim 8 , wherein the selection of the zoom factor is performed automatically by the image processing unit as a function of other state parameters.
