FOR-A to introduce real-time video Noise Eraser at NAB 2008

FOR-A Corporation of America, a manufacturer of video and
audio systems for the broadcast and professional video industries, will
introduce the DNE-2, a real-time video noise eraser, at NAB 2008 in
Las Vegas from April
14-17, 2008 (Booth #SU5220).

The DNE-2 Noise Eraser incorporates the best of FOR-A’s
image processing technology. Image processing with motion compensation
technology is used to remove only the noise-filled signals, without harming the
quality of the original video.

The DNE-2 Noise Eraser uses “motion compensation”
technology, which is also the core technology in FOR-A’s FRC-7000 Frame Rate
Converter, to maintain a high level of accuracy in the replacement information.
In noise removal, information within a video is deleted and replaced with
different information. In many noise reducers, the replacement information is
less accurate, leading to blurred contours and details in the image.

“We named the DNE-2 a ‘Noise Eraser’ instead of a ‘Noise
Reducer’ because we wanted to create a product that would accurately remove
noise only, using FOR-A’s image processing technology,” said Hiro Tanoue, FOR-A
Deputy General Manager, Overseas Operations. “It marks a significant break from
competitive products. The ‘2’ in the ‘DNE-2’ model name represents the two
filter functions that are used in the product — one to remove grain noise and
one to remove dust noise.”

The DNE-2 removes grain and dust noise from video that’s
been converted from film to video. It supports HD-SDI input and output and the
following formats: 1080/59.94i, 1080/50i, 1080/24p, 1080/24psf, 1080/23.98p,
1080/23.98psf, 720/59.94p and 720/50p.

With 1080i format materials, progressive conversion inside
the DNE-2 occurs with video converted via pulldown, enabling noise removal with
an appropriate frame rate.

In addition to noise removal for telecine video, the DNE-2
can also be used for improving S/N level, removing noise caused during image
compression and as a preprocessor for producing package media such as DVDs.
The DNE-2 also has many image processing functions,
including: process control, color correction, detail enhancer and audio delay.
