Image processing methods, and image processing devices and system for a scalable multi-projection system

An image processing device to process a first sub-image of an image split into a plurality of sub-images according to a display scheme, wherein each of the plurality of sub-images is configured to be displayed by a display device, wherein the image processing device is associated with a first display device and is configured to be connected to a source device through a first network and to at least one other image processing device through a second network, the image processing device comprising:

• at least one processor that operates to:
• receive the first sub-image from a source device via the first network;
• determine at least one part of the received first sub-image, wherein the at least one part is adjacent to at least one second sub-image received by the at least one other image processing device;
• and
• send, via the second network, the at least one determined part to the at least one other image processing device for inclusion as a part of a second clustered sub-image to be displayed by a display device associated with the at least one other image processing device, the second clustered sub-image comprising the at least one part and the at least one second sub-image being merged and appended along a common edge or border such that the second clustered sub-image is larger than the received second sub-image,
• wherein the at least one part of the first sub-image is adjacent and connected to the at least one second sub-image before the image is split into the plurality of sub-images and after the second clustered sub-image is generated, and the at least one part of the first sub-image is separated from the at least one second sub-image after the image is split and before the second clustered sub-image is generated,
• wherein a first clustered sub-image is displayed by the first display device such that at least a portion of the displayed first clustered sub-image overlaps with at least a portion of the second clustered sub-image, the second clustered sub-image being displayed by the display device associated with the at least one other image processing device, the first clustered sub-image comprising the received first sub-image and at least one part of the second sub-image being merged and appended along a common edge or border such that the first clustered sub-image is larger than the received first sub-image, and
• wherein the first clustered sub-image is generated at the image processing device and the second clustered sub-image is generated at the at least one other image processing device.

A method for an image processing device, for a multi-display system, to process a first sub-image of an image split into a plurality of sub-images according to a display scheme, wherein each of the plurality of sub-images is configured to be displayed by a display device, wherein the image processing device is associated with a first display device and is configured to be connected to a source device through a first network and to at least one other image processing device through a second network, the method comprising:

• receiving the first sub-image from the source device via the first network;
• receiving, from the at least one other image processing device via the second network, at least one part of at least one second sub-image to be displayed by another display device associated with the at least one other image processing device;
• and
• generating a first clustered sub-image to be displayed by the first display device, the first clustered sub-image comprising the received first sub-image and the at least one received adjacent part being merged and appended along a common edge or border such that the first clustered sub-image is larger than the received first sub-image,
• wherein the at least one part of the at least one second sub-image is adjacent and connected to the first sub-image before the image is split into the plurality of sub-images and after the first clustered sub-image is generated, and the at least one part of the at least one second sub-image is separated from the first sub-image after the image is split and before the first clustered sub-image is generated,
• wherein the first clustered sub-image is displayed by the first display device such that at least a portion of the displayed first clustered sub-image overlaps with at least a portion of at least one second clustered sub-image being displayed by the another display device associated with the at least one other image processing device, the at least one second clustered sub-image comprising the at least one second sub-image and at least one part of the first sub-image being merged and appended along a common edge or border such that the at least one second clustered sub-image is larger than the at least one second sub-image, and
• wherein the at least one second clustered sub-image is generated at the at least one other image processing device.
