NEC Electronics has has developed a technology for improving
the display of low-resolution images and movies on large screen
panels.
Working with NEC Corporation, NEC Electronics has achieved a
new technology for greatly reducing the blurring and graininess
that occurs when low-resolution media is magnified for
large-screen display.
The new technology is a single frame super-resolution
technology which analyzes and processes the information
contained in one frame of data to improve blurring and
graininess. It is based on an algorithm which refines the
contours of people and objects in image magnification process,
and compensates for the quality and enhances the color
rendition for crisp images.
The application of the new algorithm enhances 1seg ground
digital broadcasts from the QVGA format (320 ? 240 pixels) of
image data to the WVGA format (800 ? 400 pixels) for crisp
image display on mobile phones and car navigation systems. 1seg
is a mobile terrestrial digital audio/video and data
broadcasting service in Japan.
Additionally, the technology boosts image data in VGA format
(720 ? 480 pixels) ordinarily used for TV broadcasts and DVD
storage up to to six times the resolution, providing clear
images for HDTV (1920 ? 1080 pixels).
Before the end of summer, NEC Electronics will begin accepting
orders for ASIC (application specific integrated circuit)
products with the new technology incorporated in the IP core.
Shipping of ASICs with the single frame super-resolution is
expected to begin as early as summer 2009, with orders
projected to reach ?10 billion in fiscal year ended March 2011.
Because of the capability to improve image quality using only a
single image, the advanced IP core requires less data capacity
and can process in real time without the need for external
processing memory.
NEC said that the new IP core can be used in 1seg broadcast
receivers such as mobile phones and car navigation systems as
well as in HDTVs. |
