The controller (40) is embodied and provided to control the controllable drive device (72) in such a way that, within a predetermined range of possible orientations of the viewing direction (28) of the image capturing apparatus (20) in space, the orientation of the image display apparatus (60) in space is a predetermined function of the orientation of the viewing direction (28) of the image capturing apparatus (20) in space. ## Claims ### Claim 1 A system for holding an image display apparatus for displaying an image captured by means of an image capturing apparatus, comprising: a movable holding apparatus for an alterable hold of the image display apparatus; a controllable drive device for moving the holding apparatus, comprising a control signal input for receiving a control signal; a controller comprising a signal input for receiving a signal that represents an orientation or a change in the orientation of the viewing direction of the image capturing apparatus in space or that facilitates a determination of the orientation or the change in the orientation of the viewing direction of the image capturing apparatus, and comprising a control signal output, couplable to the control signal input of the controllable drive device, for providing a control signal for controlling the controllable drive device, wherein the controller is embodied and provided to control the controllable drive device in such a way that, within a predetermined range of possible orientations of the viewing direction of the image capturing apparatus in space, the orientation of the image display apparatus in space is a predetermined function of the orientation of the viewing direction of the image capturing apparatus in space. ### Claim 2 (depends on 1) The system according to claim 1, wherein the controller is embodied to control the drive device in such a way that, within a predetermined angle range, pivoting of the viewing direction of the image capturing apparatus about a first axis causes pivoting of the image display apparatus about a second axis. ### Claim 3 (depends on 1) The system according to claim 1, wherein the controller is embodied to control the drive device in such a way that, in respect of pivoting the viewing direction of the image capturing apparatus about the first axis and pivoting the image display apparatus about the second axis within the predetermined angle range, every angle position of the viewing direction of the image capturing apparatus is associated with an angle position of the image display apparatus. ### Claim 4 (depends on 2) The system according to claim 2, wherein the controller is further embodied to control the drive device in such a way that pivoting of the viewing direction of the image capturing apparatus about the first axis further causes a movement of the image display apparatus along a path. ### Claim 5 (depends on 1) The system according to claim 1, wherein the signal input of the controller is further configured to receive a signal that represents a position or a change in the position of the image capturing apparatus or that facilitates a determination of the position or the change in the position of the image capturing apparatus, the controller is further embodied and provided to control the controllable drive device in such a way that, within a predetermined range of possible positions of the image capturing apparatus, the position of the image display apparatus is a predetermined function of the position of the image capturing apparatus. ### Claim 6 (depends on 1) The system according to claim 1, wherein the signal input of the controller is embodied to receive from a sensor a signal or a signal that has been integrated over time. ### Claim 7 (depends on 1) The system according to claim 1, wherein the signal input of the controller is embodied to receive an image signal from a camera for capturing an operating field, the controller is embodied and provided to determine the orientation of the image capturing apparatus by evaluating an image signal received at the signal input. ### Claim 8 (depends on 1) The system according to claim 1, wherein the signal input of the controller is embodied to receive a signal from a receiver for electromagnetic waves which emanate from the image capturing apparatus, the controller is embodied and provided to determine the orientation of the image capturing apparatus in space by evaluating the signal received from the receiver. ### Claim 9 (depends on 1) The system according to claim 1, wherein the controller is embodied to control the drive device in such a way that, within a predetermined angle range, a rotation of the image capturing apparatus through a first angle about its viewing direction causes a rotation of the image display apparatus through a second angle, the second angle is a predetermined fraction of the first angle or a predetermined function of the first angle or a predetermined function of the angle position of the image capturing apparatus. ### Claim 10 A method for displaying an image captured by means of a movable image capturing apparatus, including the following steps: capturing the orientation of the viewing direction of the image capturing apparatus in space by means of a sensor; setting the orientation of the image display apparatus in space depending on the orientation of the image capturing apparatus in space. ### Claim 11 (depends on 10) The method according to claim 10, further including the following step: presenting the orientation of the image capturing apparatus in space graphically or numerically on an image display surface of the image display apparatus. ### Claim 12 (depends on 10) The method according to claim 10, further including the following step: deforming the image presented on the image display surface depending on an orientation in the viewing direction of the image capturing apparatus in space.
