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.
