Developing the stereoscopic vision display technology which can see from with
360 degree anywhere
- Photograph taken on the spot image in real time appreciation possibly -
Hitachi, Ltd. (President execution part: Manor mountain Etuhiko, below:
Hitachi), this each time, turning from with 360 degree anywhere, it developed
the new model stereoscopic vision display technology which can look at image.
With this technology, as for the viewer like wearing and hologram image of the
special glasses, it is possible to enjoy the kind of stereoscopic vision which
just floats in the sky without processing specially. In addition, jointly using
the private photographing system, stereoscopic vision of photograph taken on
the spot discrimination/reference also it is possible in real time to praise.
Through network, if photograph taken on the spot image is sent, the
presentation of
the completely new shape that is actualized
stereoscopic vision is appreciated simultaneously at the place where it is far.
Application in wide field is expected as the new information offer system where
this technology used image.
The so far, as the expedient which expresses the kind of stereoscopic vision
which surfaces in the space, holography*1)Is known widely. But, with
holography, because the interference fringes in order to play back stereoscopic
vision (hologram) the process which is created is necessary, it is not possible
to display photograph taken on the spot image in real time.
It becomes possible to implement the scene that, in the actual world if in real
time, as stereoscopic vision it becomes possible to display for example, in
order to appear in the world of the SF movie, stereoscopic vision of the person
and the object is projected photograph taken on the spot image in the sky. In
addition, it just created in Japan the mock-up (the prototype) even in the
foreign country simultaneously appreciating, such that the presentation is done
it can implement the form of new business to argument and the customer of the
commodity design.
This each time, the Hitachi human interaction laboratory which is the Hitachi
Fundamental Research Laboratories*2)The viewer 360 degrees, turning
stereoscopic vision of the real time which floated in the sky from with
anywhere, it can see, stereoscopic vision display technology was developed. In
addition, cylindrical stereoscopic vision display unit "Transpost"
was made on an experimental basis as a trial manufacture system. This time,
there is a following kind of merit in the display technology which was
developed.
(1) display of the stereoscopic vision with simple feature
As for basic principle, projecting the image of the subject which is projected
from multiple directions, simultaneously to the rotary screen which administers
uniqueness processing, it is something which displays three-dimensional image.
With trial manufacture display "Transpost", it projects to the mirror
of the top board with the liquid crystal projector which first installs image
of the subject which is projected from 24 directions, in the pedestal. It is
the mechanism that the image which is reflected with the mirror of the top
board is projected by 24 mirrors which are arranged around the rotary screen,
furthermore, reflects with this mirror and is projected to the rotary screen.
(2) indicating stereoscopic vision of
photograph taken on the spot in real time
The private photographing system which forms the image from 24 directions,
automatically vis-a-vis subject was developed. If the image which photographed
with this system directly, is transmitted to the liquid crystal projector, it
is possible to indicate the stereoscopic vision of photograph taken on the spot
in real time. In addition, if the photographing system and
"Transpost" is tied with network, photograph taken on the spot it is
possible to transmit to remote place in real time.
As for the stereoscopic vision display technology which
this time was developed, both the still picture and animated picture indication
of full color is possible from Y3YoYOYa!?Y?Y?YeYOY?Y?Y1 to photograph taken on
the spot image. Until recently it is expected to the field of business and
entertainment, as a stereoscopic vision expression of the YaYOY-Y?Y1 times
which are not and a display of information transmission, that it is utilized
widely.
< Notes >
*1)Holography: The ripple mark of the light which is reflected from the object
making use of laser light (the interference fringes) being something which is
recorded to the sensitized material, allowing to shine light, when it plays
back, the same 3 dimensional image as the original object is visible. In
addition, reproducing the interference fringes with the computer, there is also
a technique, computer hologram which draws up the three-dimensional image.
*2)The Hitachi human interaction laboratory: The research organization which
designates the Hitachi individual human interface research where designer,
technician and ????? participate as purpose. The design headquarters Aoyama
office (FEEL) with the Research Center (Kokubunji) it provides base, society of
the next generation, researching the future type interface which is applied to
life with point of view of equipment interface, human assist interface and
environmental interface.
