1.1-Micron Pixel 1/4-inch 8-Megapixel
CMOS Image Sensor Utilizes OmniBSI-2™ Technology
for Next-Generation Mobile Applications
The 1/4-inch OV8850 leads the CMOS sensor pixel design
race in the smartphone market by enabling autofocus
modules that are 20 percent slimmer than today's
1/3.2-inch 8-megapixel modules. Besides a small footprint,
the 1.1-micron OmniBSI-2 pixel offers significant
improvements in power efficiency and comparable image
quality to the previous generation 1.4-micron OmniBSI™
pixel, making it an attractive solution for next-generation
smartphones and tablets.
An integrated scaler allows the camera to maintain full field
of view in 1080p/30 high-definition (HD) video and preview
modes and provides extra adjustable resolution for
electronic image stabilization (EIS). Additionally, the
sensor's 2 x 2 binning functionality provides EIS for
720p/60 HD video recording. Other advanced features of
the OV8850 include an on-chip temperature sensor, two
PLLs, context switching, 4 Kbits of one-time programmable
memory, lens shading correction, defective pixel cancelling,
black sun elimination, and alternate row exposure for high
dynamic range (HDR) video and still image capture.
The OV8850 supports 8 and 10-bit RAW image output with
all standard image quality control functions supported
through the SCCB interface. The sensor fits in an
8.5 x 8.5 mm autofocus camera module with a build height of
4.7 mm and features a 4-lane MIPI/LVDS that facilitates the
required high data transfer rate.
