Abstract: A display device includes an image generation device configured to allow a viewer to recognize the image, a control device configured to control the image generation device, a light projector configured to output the image as light, an optical mechanism capable of adjusting a distance from a predetermined position to a position at which the light is formed as a virtual image, a concave mirror configured to reflect light passing through the optical mechanism toward a reflector, a first actuator configured to adjust the distance in the optical mechanism, and a second actuator configured to adjust a reflection angle of the concave mirror. The control device estimates a temperature of the light projector, and in a case in which the estimated temperature is equal to or higher than a predetermined upper limit temperature, the control device causes the first actuator to reduce the distance.

Abstract: A display device includes a light projector configured to project light including an image, an optical mechanism provided on a path of the light and capable of adjusting a distance from a predetermined position to a position where the light is formed as a virtual image, a concave mirror configured to reflect light passing through the optical mechanism toward a reflector, a first actuator configured to adjust the distance in the optical mechanism, and a controller configured to control the light projector and the first actuator. The controller causes the first actuator to change the distance and causes the light projector to project light including an opening image, at a time of an operation start of the display device.

Abstract: A display device mounted on a vehicle includes an image generation device configured to project image light that is light including an image toward a projection area on a front windshield, a target information acquirer configured to acquire at least a position of a target present around the vehicle, and a controller configured to control the image generation device.

Abstract: A display device includes an image generation device configured to cause an image to be superimposed on a landscape and viewed by a viewer, and a control device configured to control the image generation device, wherein the control device is configured to control the image generation device such that a display mode of the image is changed according to a gaze time during which the viewer gazes at the image output by the image generation device.

Abstract: A device for visually confirming a forward direction that allows a crew member to visually confirm a desired range on the forward side of a vehicle includes a first reflecting mirror that reflects the desired range and a second reflecting mirror that reflects a reflected image reflected on the first reflecting mirror toward the crew member, the first reflecting mirror is arranged on a dashboard that is located inside the vehicle, and the second reflecting mirror is arranged on a lower side of the dashboard, and a first light transmitting part and a second light transmitting part are disposed in an area that connects the first reflecting mirror and the second reflecting mirror and an area that connects the second reflecting mirror and an eye-point of the crew member.

Abstract: A vehicle rear viewing device includes a rear under view mirror provided to face an inner surface of a rear windshield and capable of reflecting an area below and behind a vehicle to an occupant in an interior of the vehicle. A marker indicator is to allow the occupant to view the area below and behind the vehicle through the rear under view mirror to visually recognize a position of a rear end of a vehicle body. A rear wiper is provided on a rear part of the vehicle body so as to face an outer surface of the rear windshield. The marker indicator is provided so as to be covered with at least a part of the rear wiper along a front rear direction of the vehicle in front of the rear wiper when the rear wiper is in an initial position.

Abstract: A vehicle brake light system includes a plurality of lighting units arranged in a horizontally and vertically spaced apart relation on the rear of a vehicle. Horizontally spaced apart lighting units which are lower in position have a greater distance between their centers of gravity, and are adapted to be turned on when a larger braking force is applied to a brake pedal.

Abstract: A vehicle brake light system (51) includes a plurality of lighting units (51a, 51b, 51c) arranged in a horizontally and vertically spaced apart relation on the rear of a vehicle. Horizontally spaced apart lighting units (51a, 51b, 51c) which are lower in position have a greater distance between their centers of gravity, and are adapted to be turned on when a larger braking force is applied to a brake pedal (61).
