Description
More particularly, the present invention relates to a multi-directional spatial image projection apparatus equipped with a field-separating element, and more particularly, to a multi-directional spatial image projection apparatus having a field dividing element, To a multi-directional spatial image projection apparatus equipped with a field-separating element for displaying another spatial image to an observer.
A spatial image is an image expressing depth, unlike a two-dimensional plane image, and a person can feel a three-dimensional feeling when the binocular of the person recognizes the spatial image.
A spatial image projection apparatus is a device for projecting a spatial image to provide a three-dimensional feeling as if a person is looking at a real object.
As a conventional technique, a spatial image projection apparatus of Registration No. 10-1299195 is intended by the present applicant and includes a receiving unit for receiving spatial images; A display unit for displaying the spatial image and projecting light; A control unit for controlling the display unit to display the spatial image; And a projection unit for projecting the spatial image by transmitting or reflecting the light, wherein the projection unit includes a first lens and a second lens which are liquid crystal lenses or liquid lenses located in front of the display unit, Further comprising a projection position signal for requesting a change of a position at which the spatial image is to be projected, and the control unit switches the state of the first lens and the second lens to the operation state or the inoperative state in accordance with the projection position signal And a spatial image projection apparatus.
As another conventional technique, an image reproducing apparatus and a hologram member disclosed in Japanese Unexamined Patent Application Publication No. 2003-216009 have a hologram recording medium attached to the outer circumferential surface of a light introducing block made of an optically transparent material on which a hologram stereoscopic image or hologram image is recorded And a hologram recording medium which is provided in the outer case and irradiates the hologram stereoscopic image or the illumination light for reproduction for reproducing the hologram image, And the image pickup device is mounted on the image pickup device.
However, in the conventional apparatus as described above, an image composed of a combination of a plurality of partial images output from the display unit is not limited to the prism array direction but is output in all directions, so that an entire image in which a plurality of partial images are overlapped is transmitted through each prism array There is a disadvantage in that it can not display a limited spatial image.
Therefore, when the display unit outputs an image composed of a combination of a plurality of partial images through the multi-directional spatial image projection apparatus equipped with the present invention, the viewfinder separates each partial image into a prism array corresponding to the image And a space division element for projecting a spatial image on the space through the prism array and displaying another spatial image according to the position of the observer.
The present invention includes a display unit (200) for outputting an image (100); A
