Abstract

To coordinate a coherent view across multiple display devices having an arbitrary physical layout, display offsets are determined by a computing platform based on image information received from a camera coupled to the computing platform. The computing platform may apply edge detection algorithms to determine relative positions, orientations and sizes of each of the multiple display devices from which display offsets associated with each display device may be derived as configuration settings for use in a subsequent rendering of a views to be displayed across the display devices.

Claims

1. A computer graphics rendering system, comprising:

a first and second display device having a physical layout relative to each other;

a camera to provide image information indicative of the physical layout; and

a computer platform coupled to the camera, the computer platform to execute a configuration application to determine a display offset for the first display device relative to the second display device, wherein the display offset is dependent on the physical layout and determined based on the image information provided by the camera.

2. The system of claim 1, wherein the computing platform is communicatively coupled to each of the first and second display devices and is to control graphics displayed on one or more of the display devices while receiving the image information provided by the camera.

3. The system of claim 1, wherein the computing platform is to generate a logical position value for the first display device relative to a second display device.

4. The system of claim 3, wherein the computer platform is to execute an edge detection algorithm to map, to a logical view space, a detected position of the first display device within the camera FOV relative to a detected position of the second display device.

5. The system of claim 1, wherein the computing platform is to generate an alignment offset associated with the first display device, the alignment offset indicative of a distance between a centerline of the first display device and a centerline of the second display device.

6. The system of claim 1, wherein the computing platform is to determine a screen size offset for each of the plurality of display devices based on a dimensional comparison of a graphics object as recorded by the camera, the first display device displaying the graphics object with a first dimension and the second display device displaying the graphics object with a second dimension.

7. The system of claim 6, wherein the computing platform is to determine a field of view (FOV) setting based on the screen size offset.

8. The system of claim 7, wherein the FOV setting is to approximately equalize the first and second dimensions.

9. The system of claim 1, wherein the computing platform is to determine an orientation offset for the first display device relative to the second display device.

10. The system of claim 1, wherein the computing platform is to further determine an audio configuration setting of at least one audio channel of the computer graphics rendering system to based on audio input received from a microphone of the camera.

11. A method of configuring a plurality of display devices to provide a coherent view across the plurality, the method comprising:

receiving image information from a camera having the plurality of display devices within the camera field of view (FOV);

processing the received image information to determine a parameter indicative of a physical layout of the plurality of the display devices; and

determining a display offset for a first display device based on the physical layout parameter.

12. The method of claim 11, further comprising:

setting the reference display device to be the display device approximately in the center of the camera FOV;

cycling a video test pattern through each of the plurality of displays;

detecting the cycled video test pattern with the camera; and

mapping to a logical view space a detected position of the first display device within the camera FOV relative to the reference display.

13. The method of claim 11, wherein the display offset is an alignment offset between a centerline of the first display device and a centerline of the reference display device.

14. The method of claim 11, wherein the display offset is a screen size offset between the first display device and the reference display device.

15. The method of claim 14, wherein determining the screen size offset further comprises:

displaying a graphic with a first display device;

determining a first dimension of the graphic based on the received image information;

displaying the graphic with a second display device;

determining a second dimension of the graphic based on the received image information; and

comparing the first dimension with the second dimension.

16. The method of claim 14, further comprising determining a field of view (FOV) setting based on the size offset for the first display device to provide a consistent size of a same graphic displayed on each of the first display device and the reference display device.

17. The method of claim 11, wherein the display offset is an orientation offset of the first display device relative to the reference display device.

18. The method of claim 17, wherein determining the orientation offset further comprises:

processing the received image information with an edge detection algorithm to determine a view angle offset between the first display device and the reference display device.

19. The method of claim 18, wherein determining the orientation offset further comprises:

displaying a graphic on a first display device; and

processing the received image information with an edge detection algorithm to determine if the first display device is in a portrait or landscape mode.

20. A computer-readable medium having stored thereon a set of instructions which when executed cause a processing system to perform the method of claim 11.
