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.

Abstract: An image display system includes a display unit displaying an image, a projection unit projecting in a target space a virtual image corresponding to the image with an output light of the display unit, a body unit provided thereto the display unit and the projection unit, and an image producing unit including a first correction unit and a second correction unit. The first correction unit performs a first correction processing of correcting, based on a first orientation signal indicative of a first orientation change of the body unit, a display position of the virtual image in the target space. The second correction unit performs a second correction processing of correcting, based on a second orientation signal indicative of a second orientation change of the body unit which is faster than the first orientation change, the display position of the virtual image in the target space.

Abstract: A video control device includes a processor and a memory including a program that, when executed, causes the processor to perform operations including: obtaining a position of a vehicle determined by a satellite positioning system; obtaining an estimated position of the vehicle estimated based on dead reckoning; estimating a deviation in an orientation of the vehicle, based on the position of the vehicle determined by the satellite positioning system and the estimated position of the vehicle estimated based on the dead reckoning; calculating an estimated orientation of the vehicle, based on the deviation in the orientation of the vehicle estimated; and outputting the estimated orientation of the vehicle to a video display device that displays information which is based on the orientation of the vehicle.
