Abstract

A system, in particular for image-guided surgery, comprising: at least two display devices; a position determinator for determining the relative position of the display devices; and an image generator for generating images, which are to be displayed by the display devices, in accordance with the determined relative position.

First claim

What is claimed:

1. A system comprising:
a plurality of display devices;
a position determinator for determining a relative position between the plurality of display devices; and
an image generator for generating images which are to be displayed by the plurality of display devices in accordance with the relative position between the plurality of display devices,
wherein the image generator selectively generates a first image for display on a first display device of the plurality of display devices and a second image different than the first image for display on a second display device different than the first display device responsive to a distance between the first and second display devices being, based on the determined relative position, above a predefined threshold,
wherein the image generator selectively generates the second image for enlarged display spanning the first and second display devices responsive to the distance between the first and second display devices being, based on the determined relative position, less than the predefined threshold.

2. The system of claim 1 , further comprising:
an adjustable mounting operatively coupled with the first display device, wherein the mounting comprises multiple elements and wherein two adjoining elements of the adjustable mounting are connected via an adjustable joint; and
at least one sensor for detecting a state of the adjustable joint.

3. The system of claim 1 , further comprising:
a marker device attached with the first display device, wherein the position determinator is configured to determine the relative position from a position of the marker device.

4. The system of claim 1 , further comprising:
at least one camera configured to generate an output image of the plurality of display devices, wherein the position determinator is configured to determine the relative position from the output image of the at least one camera.

5. The system of claim 1 , further comprising:
a camera attached with the first display device,
wherein the camera is configured to generate an output image,
wherein the position determinator is configured to determine the relative position from the output image of the camera.

6. The system of claim 1 , further comprising:
an adjustable mounting operatively coupled with the first display device and comprising multiple elements, wherein two adjoining elements of the adjustable mounting are connected via an adjustable joint; and
at least one actuator for adjusting a state of the adjustable joint.

7. The system of claim 1 , wherein:
the position determinator determines a relative position of each of the plurality of display devices relative to the another object other than the plurality of display devices; and
the image generator generates the images for each of the plurality of display devices depending on the relative position of each of the plurality of display devices relative to the another object other than the plurality of display devices.

8. The system of claim 1 , wherein:
the image generator selectively generates an image representing a graphical user interface for display as the first image on the first display device of the plurality of display devices and an image representing medical data for display as the second image data on the second display device responsive to the distance between the first and second display devices being, based on the determined relative position, above the predefined threshold,
the image generator selectively generates the image representing the medical data for enlarged display spanning the first and second display devices responsive to the distance between the first and second display devices being less than the predefined threshold.

9. The system of claim 8 , wherein the first display device comprises a touch-sensitive surface which is selectively functional responsive to the distance between the first and second display devices being, based on the determined relative position, above the predefined threshold.

10. A method of generating images for a plurality of associated display devices in a system, the method comprising:
determining a relative position between the plurality of associated display devices; and
generating images, which are to be displayed by the plurality of associated display devices in accordance with the determined relative position by:
selectively generating a first image for display on a first display device of the plurality of associated display devices and a second image different than the first image for display on a second display device different than the first display device responsive to a distance between the first and second display devices being, based on the determined relative position, above a predefined threshold, and
selectively generating the second image for enlarged display spanning the first and second display devices responsive to the distance between the first and second display devices being, based on the determined relative position, less than the predefined threshold.

11. The method of claim 10 , further comprising determining the relative position from a state of at least one joint which connects adjoining elements of a mounting device for the first display device.

12. The method of claim 10 , further comprising determining the relative position from positions of one or more marker devices attached with the first display device.

13. The method of claim 10 , further comprising determining the relative position from at least one output image of at least one camera, wherein the at least one output image shows the plurality of display devices.

14. The method of claim 10 , further comprising determining the relative position from at least one output image of a camera which is attached with the first display device.

15. The method of claim 10 , further comprising generating a drive signal for driving at least one actuator in order to adjust a state of at least one joint which connects two adjoining elements of an adjustable mounting which holds the first display device.

16. The method of claim 10 , further comprising:
selectively generating an image representing a graphical user interface for display as the first image on the first display device of the plurality of display devices and an image representing medical data for display as the second image data on the second display device responsive to the distance between the first and second display devices being, based on the determined relative position, above the predefined threshold; and
selectively generating the image representing the medical data for enlarged display spanning the first and second display devices responsive to the distance between the first and second display devices being less than the predefined threshold.

17. The method of claim 16 , further comprising selectively operating a touch-sensitive surface of the first display device which is selectively functional responsive to the distance between the first and second display devices being, based on the determined relative position, above the predefined threshold.

18. A non-transitory computer readable storage medium storing a computer program which, when running on a computer or when loaded onto a computer, causes the computer to:
determine a relative position between a plurality of associated display devices; and
generate images which are to be displayed by the plurality of associated display devices in accordance with the determined relative position by:
selectively generating a first image for display on a first display device of the plurality
