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.
