摘要

An apparatus includes: an image display unit including a display device having an image display surface that displays a two-dimensional image and a microlens array disposed in spaced-apart relation to the image display surface, the image display unit that displays a stereoscopic two-dimensional image by allowing the light emitted from the image display surface to form an image on an image forming plane in a space located on a side opposite to the display device with respect to the the microlens array; at least one switch; at least one illumination device that illuminates the space when the switch is turned on; and a controller that controls the display device to change the two-dimensional image displayed on the image display surface in accordance with an illuminating state of the illumination device.
