High-Performance, Feature Rich 8-Megapixel RAW CMOS
Image Sensor for Fast Growing Smart Phone Market
Based on OmniVision's proven 1.4-micron OmniBSI™ pixel
architecture, the 1/3.2-inch, 8-megapixel OV8820 delivers high
frame rate 1080p/30 and 720p/60 high-definition (HD) video
with electronic image stabilization (EIS) and full horizontal field
of view (FOV), designed specifically to meet the demands of
the rapidly growing feature and smart phone markets. The
sensor's advanced backside illumination pixel architecture
delivers excellent low-light performance, crosstalk and
quantum efficiency for the next generation of high
performance, high resolution phones. The feature rich OV8820
also offers advanced video capabilities that support mobile
YouTube and Facebook applications, making it an ideal solution
for tomorrow's video-centric camera phones.
The OV8820 operates at high frame rates, offering full
8-megapixel resolution (4:3) at 24 frames per second (fps),
and 6-megapixel resolution (16:9) at 30 fps. Moreover, its high
frame rates also support 720p HD video at 60 fps and 1080p
HD at 30 fps with EIS. The integrated scalar enables the
OV8820 to maintain full FOV and an improved signal-to-noise
ratio in 1080p mode. A high-speed, 4-lane MIPI interface
provides the necessary high data transfer rate. Other key
image processing features include 2 X 2 binning functionality
with a post-binning re-sampling filter function that minimizes
spatial artifacts and removes image artifacts around edges to
deliver clean, crisp color images, critical for achieving
best-in-class 720p video.
The OV8820 is a RAW sensor designed for 2-chip solutions,
combining the sensor and a baseband or application processor
with integrated image signal processing. It has an on-chip VCM
driver and fast mode switching between different resolutions.
The low power OV8820 also features a temperature sensor,
256-byte one-time programmable memory, lens shading
correction and defect pixel correction.
