Abstract
A two-dimensional image is displayed on a flat display device. A solid diffusion panel which is composed of six transparent panels is disposed in an optical path of image light emitted from the flat display device and is moved periodically in a depth direction. Sectional images of a 3D solid image are drawn on reflection surfaces of the six transparent panels by means of image light emitted from the flat display device. Because of the afterimage effect, a viewer can recognize, as a 3D solid image, reflection light coming from the solid diffusion panel.
Claims15
A display apparatus for a 3D solid image, comprising:
- a display device for displaying a two-dimensional image;
- an at least partially transparent reflection member that is configured to be moved in a depth direction and has, in an optical path of light emitted from a display screen of the display device, a surface for reflecting the light emitted from the display screen of the display device;
- driving means for driving the reflection member so as to move it periodically in the depth direction;
- and
- image data generating means for generating data of the two-dimensional image to be displayed by the display device so that a sectional image as obtained by cutting a 3D solid image by the surface of the reflection member being moved will be drawn on the surface of the reflection member in synchronism with a movement of the reflection member by means of the light emitted from the display screen of the display device.
