A display device includes: a light projection device configured to project light including an image; an optical mechanism provided on a path of the light and configured to be capable of adjusting a distance from a predetermined position to a position at which the light is formed as a virtual image; and a control device configured to control the light projection device. The control device corrects a position of an image formed based on an external environment of a vehicle when a distance between a gazing point of an occupant of the vehicle and a vanishing point of a travel lane of the vehicle is less than a predetermined distance, and suppresses the correction of the position of the image when the distance between the gazing point and the vanishing point is equal to or greater than the predetermined distance.

Display device, display control method, and storage medium

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.

A display device includes a light projection device which projects light including an image onto a reflector reflecting incident light to allow an observer to visually recognize the image included in the light reflected by the reflector as a virtual image, and a control device which causes the light projection device to output first light including a first image in a first case where a surrounding brightness is equal to or greater than a threshold value and causes the light projection device to output second light including a second image in a second case where the surrounding brightness is less than the threshold value.
