High performance ultra compact 8 megapixel image sensor delivers low power camera solution for next generation smart phones
SANTA CLARA, Calif., — February 15, 2011 — OmniVision Technologies, Inc. (Nasdaq: OVTI), a leading developer of advanced digital imaging solutions, today introduced its most advanced 8 megapixel image sensor to date, and the first to use OMNIVISION’s second generation OmniBSI™‑2 pixel architecture. Implementing the latest developments in backside illumination (BSI) pixel technology, the OV8830 combines low power consumption, small die size and best-in-class pixel performance with advanced image processing features. This combination allows the OV8830 to support enhanced, fast frame rate image capture and 1080p or 720p high-definition (HD) video recording, making it highly suitable for feature rich smart phones.
OmniBSI™‑2 technology is OMNIVISION’s first pixel architecture built on 300 mm wafers using a copper process with 65 nm design rules, developed in close cooperation with strategic manufacturing partner Taiwan Semiconductor Manufacturing Company Limited (TSMC). The new process and design rules enable a number of substantial improvements over OmniBSI™ technology’s already impressive performance, including improved pixel layout, better isolation, and significantly reduced crosstalk. As compared to OmniBSI™, OmniBSI™‑2 technology also provides the basis for a larger collection region in the photodiode. The results include increased sensitivity, improved image quality and enhanced color reproduction, leading to more responsive overall sensor performance.
The OmniBSI™‑2 pixel architecture offers many performance improvements over OmniBSI™ technology as applied to OMNIVISION’s 8 megapixel sensor product portfolio. These advances include a 20 percent improvement in peak quantum efficiency in all color channels, a 35 percent improvement in low-light sensitivity and a 45 percent increase in full-well capacity.
“The OV8830 sets a new performance standard in the popular 8 megapixel camera segment of the highly video-centric smart phone market,” said Vinoo Margasahayam, product marketing manager for OMNIVISION. “OmniBSI™‑2 technology allows us to offer an 8 megapixel sensor with best-in-class sensitivity and image quality, optimized power consumption and advanced features in a small footprint – qualities that we believe make it ideal for the next generation of smart phones.”
The 1/3.2‑inch OV8830 image sensor offers a range of advanced features including high frame rates, an integrated scaler, and 2 x 2 binning functionality. The scaler enables electronic image stabilization, while maintaining full field of view in 1080p/30 HD video mode. The sensor’s binning functionality with postbinning re-sampling filter minimizes spatial artifacts and removes image artifacts around edges, delivering clean, crisp color images for best-in-class 720p HD video.
The OV8830 fits into the industry standard module size of 8.5 x 8.5 x 6 mm and is now available for sampling. Mass production is expected to start in the second half of 2011.
