OMNIVISION OV03642-V67A

OV3642 3 megapixel product brief
available in
a lead-free
package
1/4-inch, 3 megapixel CameraChip™ sensor with
embedded TrueFocus™ technology
The OV3642 is the most advanced 1/4-inch, 3 megapixel
SOC CameraChip sensor on the market today, both in
terms of pixel quality as well as the new embedded
TrueFocus ISP (image signal processing). Featuring
OmniVision's high sensitivity 1.75 micron OmniPixel3-HS™
architecture, the OV3642 achieves a sensitivity of
960mV/(Lux-sec), delivering unparalleled low-light
performance, which is crucial for all new high frame rate
video applications and taking pictures without a flash.
The embedded TrueFocus ISP (image signal processing)
provides all functionality of a complete camera on a single
chip, and features extended depth of field (EDoF)
capabilities. The unique TrueFocus capabilities can be
used with either wave front coded (WFC) lenses as well as
standard traditional lenses, generating sharper and
clearer images and videos to give the ultimate imaging
experience for all camera phone applications.
The OV3642 has an embedded microcontroller to support
an internal auto focus engine, a programmable general
purpose I/O for external auto focus control, and an
internal anti-shake engine for image stabilization. It uses
proprietary sensor technology to improve image quality by
reducing or eliminating common lighting and/or electrical
sources of image contamination to produce a clean, fully
stable, color image. All required image processing
functions are programmable through the SCCB interface,
MIPI interface or the integrated microcontroller.
The OV3642 image array operates at up to 15 frames per
second (fps) in full resolution (QXGA) transferred over a
two-lane MIPI interface, or a traditional digital video port
(DVP). The sensor contains an integrated JPEG
compression engine, simplifying bandwidth limited
interfaces. The OV3642's advanced TrueFocus ISP can also
be used by an external secondary camera via its DVP while
providing continued output through the MIPI interface.
With all its added capabilities, the OV3642 still fits in a
standard 8.5 x 8.5mm socket!
