Abstract: A video display system according to an embodiment includes a display unit, a projection unit, and a display control unit. The display unit displays an image thereon. The projection unit projects a virtual image corresponding to the image onto a target space with outgoing light of the display unit. The display control unit is able to change a projection distance from a viewpoint of a user, who is viewing the virtual image, to the virtual image projected onto the target space. The display control unit changes the projection distance in a change pattern. The change pattern varies according to situation information.

Abstract: A peripheral information obtaining unit, a road information obtaining unit, and a communication unit which are included in a driving environment obtaining unit obtain information indicating a current state of a drive environment. A driver information obtaining unit and a vehicle information obtaining unit which are included in a driving state obtaining unit obtain information indicating a driving state of a current driver. A display controller controls at least one of a display position and a display timing of a guidance sign to be displayed on a display unit, based on at least one of the pieces of information which are output from the driving environment obtaining unit, the driving state obtaining unit, and a route guiding unit.

Abstract: The head-up display includes an imaging position changer configured to change a position of a virtual image between a far visual position far from an observer and a near visual position close to the observer. The imaging position changer inclines the virtual image at the far visual position by a second inclination angle with respect to a perpendicular plane to a reference light beam reaching a center of a viewpoint region in which a viewpoint of the observer is located, to move an upper end thereof in a forward direction of the moving object, and inclines the virtual image at the near visual position by a first inclination angle smaller than the second inclination angle with respect to the perpendicular plane to the reference light beam, to move the upper end in the forward direction of the moving object.

Abstract: A video display system includes a display unit, a projection unit, and a display control unit. The display unit displays an image. The projection unit projects a virtual image onto a target space with outgoing light of the display unit. The display control unit shifts a projection position of the virtual image by changing at least one of a projection distance or an angle of depression. The projection distance is a distance from a viewpoint to the virtual image. The angle of depression is an angle from which the virtual image is viewed from the user's viewpoint. The display control unit changes the projection distance of the virtual image in accordance with a distance instruction and changes at least one of the projection distance or the angle of depression such that the virtual image is projected onto a displayable region of the target space.

Abstract: A video display system according to an embodiment includes a display unit, a projection unit, and a display control unit. The display unit displays an image thereon. The projection unit projects a virtual image, corresponding to the image, onto a target space with outgoing light of the display unit. The display control unit performs change processing of changing, in accordance with at least one of a projection distance or an angle of depression, specifics of sway correction for correcting sway of the virtual image with respect to the target space. The projection distance is a distance from a viewpoint of a user, who is viewing the virtual image projected onto the target space, to the virtual image. The angle of depression is an angle from which the virtual image is viewed from the user's viewpoint.

Abstract: Display device included in a moving body includes road information acquisition unit that acquires road information about a road in a traveling direction of the moving body and display controller that displays a virtual image illustrating at least one graphic as seen from the moving body on a display medium while superimposing the virtual image on a real space in the traveling direction when the at least one graphic is assumed to be disposed at a predetermined position in the traveling direction. Display controller updates a mode of the at least one graphic using the road information acquired by the road information acquisition unit, and displays the virtual image illustrating the updated at least one graphic on the display medium.
