- the working distance for imaging the light has a certain effective range rather than a single, so that a plurality of three-dimensional two-dimensional images can be obtained. It becomes possible to form an image. In other words, it becomes possible to observe a plurality of image planes.
- the stereoscopic two-dimensional image display device (100, 150, 200, 250, 300, 350) according to each embodiment of the present invention, on one optical vehicle.
- An image transmission panel 17 that displays light and forms a stereoscopic two-dimensional image
- an image display surface (l la that is spaced apart from the image transmission panel 17 on the one optical axis and displays a two-dimensional image.
- the distance between the image transmission panel 17 and the image transmission panel 17 is set individually so that a plurality of stereoscopic two-dimensional images (13a, 13b) are displayed in the space 15. 21a and 21b can be formed in the space 15, and the relief effect and unexpectedness can be improved, and sufficient stereoscopic effect can be obtained. Therefore, a high performance effect can be maintained.
- the image transmission panel 17 that displays a stereoscopic two-dimensional image by imaging light on one optical axis;
- An image display surface (l la, 27a) that is spaced apart from the image transmission panel 17 and displays a two-dimensional image, and emits light from the image display surface (l la, 27a) to the image transmission panel 17
- a three-dimensional two-dimensional image display method in an apparatus (100, 150, 200, 250, 300, 350) having a plurality of display lamps B (11, 27). 27) and the image transmission panel 17 are individually set, and a plurality of two-dimensional two-dimensional images are displayed in space.
- the image plane is A plurality of images can be arranged in the viewing direction, and by displaying images based on the perspective on the respective imaging surfaces 21a and 21b, the stereoscopic effect can be greatly improved as compared with the conventional case.
- FIG. 1 is a diagram showing a configuration of a stereoscopic two-dimensional image display device according to a first embodiment.
- FIG. 2 is a view taken along arrow A_A in FIG.
- FIG. 3 is a diagram showing a configuration of a stereoscopic two-dimensional image display device according to a second embodiment.
- FIG. 4 is a diagram showing a configuration of a stereoscopic two-dimensional image display device according to a third embodiment.
- FIG. 5 is a diagram showing a configuration of a stereoscopic two-dimensional image display device according to a fourth embodiment.
- FIG. 6 is a diagram showing a configuration of a stereoscopic two-dimensional image display device according to a fifth embodiment.
- FIG. 7 is a diagram showing a configuration of a stereoscopic two-dimensional image display device according to a sixth embodiment.
- FIG. 8 is a block diagram showing a schematic configuration of a video signal supply unit.
- FIG. 9 is an explanatory diagram showing an example of video displayed on the first display unit and the second display unit.
- FIG. 10 is an explanatory view showing an image observed by an observer when the image of FIG. 9 is formed on the imaging plane.
- FIG. 11 is an operation explanatory diagram when the DFD method is used in the stereoscopic two-dimensional image display device according to the present invention.
