  • Publication number: 20180191990
    Abstract: A projection system includes a projector projecting a projection image, and a processor acquiring position information on at least one of first and second targets based on detection information obtained by a sensor, and performing a process of generating the projection image. The processor performs, when the first target and the second target are determined to have satisfied given relationship based on the position information acquired, a process of changing a content of at least one of a first projection image to be projected onto the first target and a second projection image to be projected onto the second target.

  • Patent number: 9106906
    Abstract: An image generation system includes an object space setting section that sets an object space in which a plurality of objects are disposed, and an image generation section that generates a first-viewpoint image viewed from a first viewpoint in the object space, and a second-viewpoint image viewed from a second viewpoint in the object space, the first viewpoint and the second viewpoint implementing stereovision. The image generation section performs a drawing process to generate the first-viewpoint image and the second-viewpoint image, the drawing process changing a display state of an object in a direction from an inner drawing area toward an area outside the inner drawing area, the inner drawing area being positioned within a common area of a first-viewpoint view volume corresponding to the first viewpoint and a second-viewpoint view volume corresponding to the second viewpoint.

  • Publication number: 20130257857
    Abstract: An image projected onto a screen from a projector is generated as follows. Specifically, two virtual viewpoints that correspond to the right eye and the left eye of a viewer are set in a virtual three-dimensional space, and two virtual planes are set to be circumscribed to the screen (plane of projection). A plane image is generated by perspective projection transformation of a game space onto the virtual plane based on each virtual viewpoint. A projection image is generated from each plane image according to the relationship between the pixel position of the virtual plane and the pixel position of the projection image that is defined so that the plane image is observed without distortion when observing the screen from a presumed viewing position to generate a right-eye projection image and a left-eye projection image.

  • Publication number: 20120306860
    Abstract: An image generation section of the image generation system generates a stereoscopic image so that an information display object is stereoscopically displayed at a first depth position when a parallax level has been set to a first parallax level, and is stereoscopically displayed at a second depth position when the parallax level has been set to a second parallax level. The image generation section generates the stereoscopic image so that a first edge of the information display object is stereoscopically displayed within a first area when the parallax level has been set to the second parallax level, a first boundary plane being a boundary plane specified by a line segment that connects the first edge and a third viewpoint when the parallax level has been set to the first parallax level, and the first area being an area positioned between the first boundary plane and a first clipping plane.
