Abstract: A video projection method of the present disclosure is a video projection method by a video projection system including a first projector, a second projector, and a controller that transmits video data to the first projector and the second projector. The first projector projects first projection video whose projection position moves in a first region based on the video data transmitted from the controller, the second projector projects second projection video onto a second region based on the video data transmitted from the controller, and at least one of resolution and brightness of the first projection video is adjusted in a superimposed region where the first region and the second region overlap.

Abstract: A position and size adjustment support method supports an adjustment work to achieve a predetermined position and size relation between a display range of a display apparatus and a shooting range of an imaging apparatus. An image of at least a part of the display range is shotten by the imaging apparatus. A position and size relation between the display range and the shooting range is calculated based on the image. At least one of a moving direction and a size change direction of at least one of the display range and the shooting range is calculated, based on the position and size relation calculated, the moving direction and the size change direction being used to change the position and size relation to the predetermined position and size relation. Adjustment guide information providing with the at least one of the moving direction and the size change direction calculated is output.

Abstract: A projection system includes a visible light projector, a camera and an image processor. The visible light projector projects an image with visible light onto the object. The camera captures an image of the object and has an optical axis not coinciding with an optical axis of the visible light projector. The image processor generates an image to be projected with visible light onto the object based on the image captured by the camera. The image processor includes a corrector and an image generator. The corrector corrects a deviation between a projection image and the object. The corrector is configured to calculate a projection region on the object onto which an image is projected by the visible light projector. The image generator is configured to generate image data to project the image to be projected onto the object onto the projection region.
