Abstract: A display control device includes processing circuitry to acquire traveling environment information; to estimate driving skill of the driver; to detect a direction of a line of sight of the driver; to accumulate information on movements of the sight line direction and driving action information; to calculate a visual field range and a visual recognition level indicating ease of recognition of each of a plurality of sections in the visual field range by the driver's vision based on the information on the movements of the sight line direction and the driving action information accumulated in the memory and at least one of the traveling environment information and the driving skill information; and to receive display information and to control at least one of a display position and a display method of an image on a basis of the display information.

Abstract: A line of sight of a driver is detected based on an image of the driver obtained by image-capturing; whether the driver is viewing the image display unit or viewing an outside of the image display unit is judged based on the detected line of sight; glare is detected based on the image of the driver; and a luminance level of the image displayed by the image display unit is determined based on the glare at the time of viewing the image display unit and the glare at the time of viewing the outside of the image display unit. The visibility of the displayed image can be improved even when the driver feels glare because of external light falling upon the driver's eyes.

Abstract: An aerial image display device includes an image display unit to display an image; an aerial image formation optical system to cause diffuse light emitted from the image display unit to form an image again in a different space by reflecting the light multiple times and allowing the light to pass through; and processing circuitry to acquire viewpoint position information on an observer viewing a point where the diffuse light is caused to form the image again by the aerial image formation optical system, and to control the image from the image display unit depending on an angle formed by a straight line connecting an end point of a retroreflective sheet and an eye of the observer and a straight line extending from the eye of the observer and reaching the retroreflective sheet right in front.

Abstract: An image display device includes a panel in a curved surface shape that lets through and reflects light, a first display unit that displays a first image based on first image data that reaches a predetermined position through the panel, a second display unit that displays a second image based on second image data that is reflected by the panel and reaches the predetermined position, a position information acquisition unit that acquires position information indicating a position of an actual viewpoint of an observer, and an image processing unit that determines a scaling factor of the second image data for each scan line based on the position information and performs a scaling process for each scan line on the second image data to be inputted to the second display unit.

Abstract: A floating image display device includes an image display, a floating image formation optical system that causes diffuse light emitted from the image display to form an image again in a space, a viewpoint position detector that acquires viewpoint position information on an observer observing the diffuse light that has passed through the floating image formation optical system, and display control circuitry. The display control circuitry estimates a floating image formation region, in which the observer perceives an image display surface in the space, based on positional relationship in the floating image formation optical system and the viewpoint position information, estimates image resolution in the floating image formation region based on the viewpoint position information and the positional relationship in the floating image formation optical system, and outputs the display image information to the image display based on information on the floating image formation region and the image resolution.
