1/5-Inch 3-Megapixel CMOS Image Sensor Based on
OmniBSI™ Technology Delivers Best-in-Class Sensitivity
and 720p HD Video for Entry Level Smart Phones

available in
a lead-free
package
The OV3660 is OmniVision's first 3-megapixel CMOS image
sensor based on its OmniBSI™ pixel architecture. Extending
the company's portfolio of BSI sensors, the 1.4-micron
OmniBSI pixel architecture enables the OV3660 to offer
high performance imaging and 720p high-definition (HD)
video in an ultra-compact 1/5-inch optical format, making it
an ideal choice for entry-level and mainstream smart
phones. Because the OV3660 fits into an industry-standard
6.5 x 6.5 mm module it offers a quick and easy upgrade from
existing 2-megapixel camera designs.
The OV3660 supports 720p HD video recording at
30 frames per second (fps) with cropping and scaling, as well
as 4:3 still image capture, allowing users to capture and
share both HD video and photography. For still images, the
sensor outputs JPEG compressed images that are
ready-to-use, allowing the OV3660 to be integrated into a
broad selection of platforms. The sensor also supports
Scalado™ SpeedTags for faster image rendering that
improves user experience for the preview and zoom modes.
The OV3660 offers automatic image control functions
including exposure control, white balance, auto 50/60 Hz
flicker detection, and black level calibration. Additional
features include color saturation, hue, gamma, sharpness
(edge enhancement), lens correction, defective pixel and
noise cancellation. Camera controls are accessed over a
standard serial camera control bus interface and RAW or
YUV video data is output through a parallel output
interface.
