Abstract: A display device has a movable screen that is movable in a movement direction, a drive controller, a projector, and a position detector. The drive controller moves the movable screen relative to a reference position set at a prescribed position in a movement range of the movable screen. The projector performs drawing on the movable screen by irradiating the movable screen with light used for scanning the movable screen and projects a virtual image onto a target space based on light that passes through the movable screen. The position detector executes position detection processing for detecting that the movable screen is located at a detection position set in relation to the prescribed position. The position detector moves the movable screen and executes the position detection processing in a non-display period in which the movable screen is not irradiated with light from the projector.

Abstract: A video display system includes: a screen on which an mage for displaying a virtual image is projected; a light source that emits laser light; a scanner that projects the image onto the screen by biaxially scanning the laser light onto the screen; and a controller that generates the image and controls the light source using an image signal for causing the generated image to be projected onto the screen by the laser light, and receives an input of sensing information measured using a temperature sensor and controls the scanner in accordance with the input sensing information. When the sensing information indicates a temperature outside a given temperature range, the controller causes the scanner to reduce an amplitude of the biaxial scanning in at least one axial direction to a smaller value than when the sensing information indicates a second brightness or a temperature within the given temperature range.

Abstract: Provided is a display device that allows a distance from a display medium to an object ahead to be easily ascertained. The display device includes a display unit that projects a light beam onto a windshield so as to be reflected from the windshield such that a virtual image is displayed in a space further than the windshield in the depth direction, and a controller that controls the display unit so that a reference pattern to be superimposed on a pedestrian present in the space is displayed so as to correspond to the position of the pedestrian.
