Abstract

A projection system and an operation method thereof are provided. The projection system includes a video and audio source, an image duplication unit, a plurality of image segmentation units, and a plurality of projectors. The video and audio source receives a sum image parameter, and provides a non-standard format image. The image duplication unit receives and sends one of sum image parameters to the video and audio source. The image segmentation units provide the same sum image parameters, though only one is transmitted to the video and audio source through the image duplication unit. Each of the image segmentation units receives the non-standard format image, and segments a part of the non-standard format image as a standard format image, where the standard format images are partially overlapped with each other. The projectors are respectively coupled to the corresponding image segmentation unit, and display according to the corresponding standard format image.

Claims

1. A projection system, comprising:

a video and audio source, receiving a sum image parameter, and correspondingly providing a non-standard format image;

an image duplication unit, coupled to the video and audio source, receiving a plurality of image parameters, and providing the sum image parameter according to the image parameters;

a plurality of image segmentation units, coupled to the image duplication unit, and respectively providing the corresponding image parameter, wherein each of the image segmentation units receives the non-standard format image through the image duplication unit and segments a part of the non-standard format image as a standard format image, wherein the standard format images provided by the image segmentation units are partially overlapped with each other; and

a plurality of projectors, respectively coupled to the corresponding image segmentation unit, for displaying according to the standard format image provided by the corresponding image segmentation unit.

2. The projection system as claimed in claim 1, wherein each of the image segmentation units captures a corresponding part of the non-standard format image to generate the corresponding standard format image.

3. The projection system as claimed in claim 1, wherein the image segmentation units receives an image setting signal, and provide the image parameters according to the image setting signal, and the image duplication unit selects one of the image parameters to serve as the sum image parameter.

4. The projection system as claimed in claim 1, wherein the image segmentation units respectively inspect optimum resolutions of the projectors to provide the image parameters, and the image duplication unit calculates according to the image parameters and an image overlap rate to generate the sum image parameter.

5. The projection system as claimed in claim 1, wherein optimum resolutions of the projectors are completely the same.

6. The projection system as claimed in claim 1, wherein a resolution of the standard format image is the same with an optimum resolution of the projections.
