-----What sort of system
is used within the HDPS100?
As far as the customer is concerned, the product
simply provides a high-definition image. But the HDPS100 unit actually
contains a central processor that automatically divides up the visual
data between the nine projectors. It also controls all the color, strain,
brightness and contrast so that all you see is a single, unified image.
The HDPS100 system is composed of the screen, the
projectors, a processor, and a calibration system that sorts out the
images being displayed. At the core of this system is technology that
overlaps multiple images and unifies them into a single image being broadcast
onto a huge screen. The calibration system simplifies this complex process.
And images, which would have taken a long time to compose and project
can now be completed in just ten or twenty minutes.
The HDPS100 system works with a wide range of visual
data input; it does not necessarily have to be four million-pixel high-definition
data. For example, the system can display the Digital HiVision broadcasts
that are rising in popularity in Japan, which contain two million-pixel
data. That's enough high-definition to work with this system. It can
even work with conventional analog television broadcasts in NTSC format.
Although the image resolution in such broadcasts is relatively poor,
there is plenty of visual data available from existing sources--so they
can be shown as well.
The system is therefore quite adaptable. One moment you can use the HDPS100 for
high-definition images, the next you can use it to show Digital HiVision broadcasts.
You could even use it for a Powerpoint presentation. Although the data themselves
are not high-definition, the presentation still looks great because the screen
brightness is so high. We think the system could therefore be used at meetings
or conferences, as well as for medical applications.
The reason why we have been able to develop such a powerful system is that the
research and product development teams have worked very closely together on the
project. The control technology required for this kind of image display is extremely
difficult to achieve. But thanks to the round-the-clock efforts of Mr. Komiya
and his team at the Imaging Technology Department, we've managed to do it! |
