High Performance, Ultra Compact 8-Megapixel CMOS Image
Sensor Based on OmniBSI-2™ Delivers Low Power HD
Mobile Imaging Solution for Next Generation Smart Phones
The OV8830 is OmniVision's first sensor built on the company's second
generation OmniBSI-2™ backside illumination (BSI) pixel architecture.
It delivers optimized power consumption and best-in-class pixel
performance that enable enhanced image capture and high frame rate
1080p and 720p high-definition (HD) video recording. Manufactured
combining a copper process on 300 mm wafers using 65 nm design rules,
the 1/3.2-inch OV8830 is highly optimized for the next generation smart
phone market.
Benefits of OmniBSI-2 technology found in the OV8830 include
optimized die size, a bigger collection region in the photodiode enabled
by custom design rules, a significant reduction in power consumption,
and 1.14 ~ 1.32V digital core. Key improvements over the first
generation OmniBSI architecture include a 20 percent improvement in
peak quantum efficiency in all color channels, 35 percent improvement
in low-light sensitivity, and 45 percent increase in full well capacity.
OmniBSI-2's custom pixel design rules also enable better pixel layout,
better isolation, and significantly reduced crosstalk. Each of these
advances represent additional performance improvements over the first
generation OmniBSI technology resulting in better image quality,
enhanced color reproduction, and improved overall camera performance.
In full 8-megapixel (3264 x 2448) resolution, the OV8830 operates at
24 frames per second (fps) in a 4:3 format and in 6-megapixel
(3264 x 1836) resolution at 30 fps in a 16:9 format. These higher frame
rates enable a number of key benefits, including: no image lag for
shutter-less designs, continuous shooting, minimized rolling shutter
effect, real-time image capture with no lag between resolutions, and
full HD at 30 or 60 fps.
The OV8830 is a RAW sensor designed for 2-chip solutions that involve
the sensor working in conjunction with a baseband or an application
processor with integrated image signal processing. Additional
integrated features of the OV8830 include an integrated scaler,
2x2 binning, re-sampling filter, alternate row high dynamic range
timing support, context switching, temperature sensing, 4 Kbits of
one-time programmable memory, lens shading correction, and defect
pixel correction. The OV8830 fits into the industry standard module size
of 8.5 x 8.5 x 6 mm, and a high-speed, 4-lane mobile industry processor
interface (MIPI) facilitates the required high data transfer rate.
