Abstract: The disclosure provides an image blending method. The method includes projecting a plurality of images onto a projection surface, respectively, wherein an image of the first portion of the first image and an image of the first portion of the second image projected onto the projection surface overlap each other in the first overlapping area on the projection surface; the image parameters of all pixels of the first non-overlapping area and the second non-overlapping area are adjusted according to the position of the first non-overlapping area and the position of the second non-overlapping area, such that the black-level brightness of the first non-overlapping image in the first non-overlapping area of the first image and the black-level brightness of the second non-overlapping image in the second non-overlapping area of the second image are close to the black-level brightness of the first overlapping image in the first overlapping area.

Abstract: The disclosure provides an image blending method. The method includes projecting a first image and a second image onto a projection surface by a first projector and a second projector, respectively, and the first image and the second image overlap each other; and projecting the first control pattern onto the first image, adjusting the first control pattern such that a first control pattern frame matches a boundary of an overlapping area, and thereby identifying a position of a first non-overlapping area in the first image. Additionally, a similar operation is performed by the second projector to identify a second non-overlapping area in the second image. All pixels in the first non-overlapping area and the second non-overlapping area are adjusted such that the black-level brightness of the first non-overlapping area and the second non-overlapping area correspond to the black-level brightness of the overlapping area to obtain better brightness uniformity.

Abstract: A projection display system and a correcting method are provided. The projection display system includes a plurality of projection devices, an image capturing device, a blending device and computing device. The projection devices are configured to project a plurality of projection regions to a projection surface. The image capturing device is configured to capture an image on the projection surface.

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.
