Rambus Inc. (NASDAQ: RMBS), the innovative technology solutions company that
brings invention to market, today unveiled breakthrough binary pixel
technology that dramatically improves the quality of photos taken from mobile
devices. The Rambus Binary Pixel technology includes image sensor and image
processing architectures with single-shot high dynamic range (HDR) and
improved low-light sensitivity for better videos and photos in any lighting

“Today’s compact mainstream sensors are only able to capture a fraction of
what the human eye can see,” said Dr. Martin Scott, chief technology officer
at Rambus. “Our breakthrough binary pixel technology enables a tremendous
performance improvement for compact imagers capable of ultra high-quality
photos and videos from mobile devices.”

As improvements are made in resolution and responsiveness, more and more
consumers are using the camera functionality on their smart phone as the
primary method for taking photos and capturing memories. However, high
contrast scenes typical in daily life, such as bright landscapes, sunset
portraits, and scenes with both sunlight and shadow, are difficult to capture
with today’s compact mobile sensors - the range of bright and dark details in
these scenes simply exceeds the limited dynamic range of mainstream CMOS

This binary pixel technology is optimized at the pixel level to sense light
similar to the human eye while maintaining comparable form factor, cost and
power of today’s mobile and consumer imagers. The results are
professional-quality images and videos from mobile devices that capture the
full gamut of details in dark and bright intensities.

Benefits of binary pixel technology:

  *Improved image quality optimized at the pixel level
  *Single-shot HDR photo and video capture operates at high-speed frame-rates
  *Improved signal-to-noise performance in low-light conditions
  *Extended dynamic range through variable temporal and spatial oversampling
  *Silicon-proven technology for mobile form factors
  *Easily integratable into existing SoC architectures
  *Compatible with current CMOS image sensor process technology

The Rambus binary pixel has been demonstrated in a proof-of-concept test-chip
and the technology is currently available for integration into future mobile
and consumer image sensors. For additional information visit
