FOCUS Enhancements, Inc. Awarded Two New Patents For Video Technology; Enhanced Text Clarity and Reduced Flicker are Key to 2-D Filter Patent.

Business/Technology Editors

CAMPBELL, Calif.--(BUSINESS WIRE)--March 20, 2002

In the rapidly evolving and highly competitive world of Video Processing, Video Scan Conversion, Digital Video, and Video Production, FOCUS Enhancements (NASDAQ: FCSE) of Campbell, California, announced the recent grant of two patents which enhance picture quality in various video formats. These patents are especially important in protecting the core technology in the Company's proprietary semiconductors.

"This intellectual property adds to the existing and rapidly growing array of tools already utilized by FOCUS Enhancements in our video display technology," commented Thomas Hamilton, Executive Vice President and General Manager of the FOCUS Enhancements Semiconductor Division. "The 2-D Adjustable Flicker Filter, key to the crisp portrayal of text, has already been incorporated into the company's full line of semiconductor products. The Deinterlacer patent is core to cost-effective products for HDTV, flat panel displays, and other progressive displays."

Two-Dimensional Adjustable Flicker Filter - This invention provides the user with the ability to reduce flicker while maintaining image detail. This significantly enhances the sharpness and readability of text in fine detail fonts, which is very noticeable in Asian characters. Two independent controls allow the user to adjust the two-dimensional system characteristics. Contrary to one-dimensional flicker filtering, which can cause blurred text when flickering is suppressed, the two-dimensional filter maintains picture clarity and sharpness while significantly suppressing flicker caused by high adjacent pixel intensity differentials.

Motion Adaptive De-Interlace Filter - This invention provides a mechanism for filtering motion-related artifacts from de-interlaced images. The Motion Adaptive De-Interlace Filter relates generally to methods for reducing or eliminating motion artifacts on a pixel-by-pixel basis, which occurs during conversions of conventional interlaced TV images to progressive TV display formats. This approach reduces the need for costly field memory while effectively eliminating the motion artifacts and maintaining full frame image detail. Motion variances are determined through interpolative comparisons and corrected automatically through the de-interlacing process on a pixel-by-pixel basis.
