以下是这篇中文报导的部份英文摘录. 这家公司, real d, 还是采用偏光镜技术,
所以萤幕需要配合安装不同的材质, 而画质还是有所折损. 这样比较合理,
因为偏光镜的成本才会便宜.
这篇中文报导还是引用失当: IMAX也是用偏光镜, 不是厚重的电子眼镜.
下次去IMAX戏院时, 戴上偏光镜後, 可以试着把头向左或向右旋转九十度,
即可发现, 看到的立体影像会有"前变後, 後变前"的反效果.
----------------------------------
The system is hardly perfect. It requires installing a special silver screen,
which is a disadvantage for showing standard movies; the rapid frame rate
diminishes the resolution of the image, from 2,048 pixels to roughly 1,700;
and even Real D executives acknowledge that the system would be impractical
for theaters with more than 300 seats because of screen-size constraints.
The main disadvantage of the Real D system is cost:
The company charges at least $50,000 up front for each theater, and $25,000
a year.
Tom Stephenson, president and chief executive of Rave Motion Pictures,
based in Dallas, said he had signed up to convert 9 of his 300 screens to
Real D and was exploring whether to charge a dollar or two more for tickets,
or whether increased ticket sales and concession receipts would ultimately
cover his costs.
