Abstract
A floating image display device includes a floating-image-formation optical system that forms an image at an opening part as a floating image from an image displayed on an image display unit, an authentication unit that judges whether or not a subject passing through the opening part is an authorized subject, and an image control unit that makes the image display unit switch contents of the image when the subject is judged as the authorized subject. The floating-image-formation optical system can include a beam splitter and a retroreflective sheet. Another floating image display device includes an image display unit that displays a first image, a floating-image-formation optical system that forms an image at an opening part as a floating image from the first image, and an image projection unit that projects a second image onto a subject moving through the floating image when the subject passes through the opening part.
