Abstract: Disclosed herein is a method of correcting an image overlap area. More specifically, the method includes steps of identifying an overlap area between images projected by a plurality of projectors, determining a difference in at least one of brightness and color between the overlap area and non-overlap area of images, analyzing RGB information of a projected image, and controlling brightness or color of an image projected on the overlap area or the non-overlap area in response to the RGB information.

Abstract: An image correction method is disclosed. The method includes at least: identifying an overlapped area in an image projected by a plurality of projectors; determining a difference of at least any one of brightness and color of the overlapped area and a non-overlapped area of the image; and adjusting a factor among the brightness and the color in which the difference is generated.

Abstract: The present invention provides a guide image generation device including a database unit which stores parameters representing the structure of a multi-projection theater and a guide image generation unit which generates a guide image that will be used in an image correction process of the multi-projection theater using the parameters stored in the database unit.

Abstract: The present invention provides a multi-projection system for extending a visual element of a main image, the system including a main projection surface on which a main image is reproduced and an auxiliary projection surface arranged around the main projection surface, in which a visual element associated with the main image is displayed on the auxiliary projection surface.

Abstract: The present invention provides a “multi-projection system” including a plurality of projection surfaces arranged so as not to be parallel to each other and two or more projection devices for projecting images on the plurality of projection surfaces, in which the two or more projection devices include a refraction projection device in which projection light is refracted before it reaches a projection surface.

Abstract: Disclosed herein is a method of generating multi-projection images. The method of generating multi-projection images includes controlling a plurality of different types of filming devices so that the filming devices are disposed at specific angles, controlling the shutter operations of the plurality of different types of filming devices in order to synchronize the plurality of different types of filming devices, and controlling the plurality of different types of filming devices so that the filming devices perform filming operations in a plurality of viewpoint directions.

Abstract: Disclosed herein is a rig for multi-camera photographing. The rig for multi-camera photographing includes a cover frame, a center base plate fixed and installed in a center line over the cover frame, and a left rotational movement plate and a right rotational movement plate disposed on the left and right sides of the center base plate and disposed in such a way as to rotatably move around rotational movement shafts protruded over the cover frame.

Abstract: Disclosed herein are a method and apparatus for normalizing the size of content in a multi-projection theater and a computer-readable recording medium. The method may include receiving theater parameters stored in a database, computing the scale factor of an image projected on a main screen based on the received theater parameters, controlling the image projected on the main screen by applying the computed scale factor to the image, and controlling the scale of an image projected on a sub-screen according to the controlled image of the main screen.

Abstract: The present invention provides a multi-projection system including two or more projection devices which project images on a plurality of projection surfaces and a management device which manages the images projected by the two or more projection devices and controls the two or more projection devices, the two or more projection devices projecting synchronized images on the plurality of projection surfaces.

Abstract: The present invention provides a multi-projection system using an interior surface as a projection surface, the system including a screen installed in a single theater, a plurality of interior surfaces arranged around the screen, and two or more projection devices for projecting synchronized images on the screen and the interior surfaces.

Abstract: The present invention provides a multi-projection system and method including direction-changeable audience seats, and the multi-projection system includes a plurality of projection surfaces installed in a single theater; and an audience seat whose direction is changed depending on images projected on the plurality of projection surfaces.

Abstract: A multi-projection system having a plurality of projection surfaces onto which images are projected is provided, where the plurality of projection surfaces are disposed on two or more sides not parallel to each other. The multi-projection system provides high three-dimensional images and a high degree of immersion in images and further provides multi-view images, thereby making theater customers feel like they really exist in the space described through the images.

Abstract: The present invention provides a projection device management system including two or more projection devices which project images on a projection surface; and a management device which corrects the image projected by each projection device based on information on each projection device and manages information for maintenance of each projection device, the two or more projection devices being installed in the same theater.

Abstract: The present invention provides a simulated-image management device for providing a simulated image of a multi-projection system, the simulated-image management device including a simulated-image management unit which generates a simulated image that indirectly shows that specific image content is reproduced in a specific multi-projection theater, wherein the simulated image is an image showing that the specific image content is reproduced on a plurality of projection surfaces included in the specific multi-projection theater.
