OMNIVISION OV06680-VL9A

OV6680 SGA product brief
available in
a lead-free
package
optimal low-light sensitivity and pixel performance for video
conferencing cameras in 3G mobile phones
The OV6680 is a single-chip, high-performance
SquareGA™ (SGA™) resolution (400x400) CameraChip™
sensor that incorporates all the functionality of a
camera and image processor in one small footprint
package. Using a 3.6 μm x 3.6 μm pixel built on
OmniPixel2™ technology utilizing a 0.18 μm CMOS
process, the OV6680 has outstanding low-light
performance to accommodate any lighting condition.
The OV6680 color camera is an excellent candidate for
secondary handset cameras for 2-way video
conferencing over 3G networks. This is enabled by its
ultra small module design (5x5x3.0 mm) and superior
low-light performance. Low light performance is most
critical for video conferencing applications because
LCD screens emit very little light (about 1 lux) and
indoor environments tend to be less bright.
Additionally, by outperforming smaller VGAs, it is also an
excellent alternative as a primary camera for low cost mobile
phones. The OV6680 provides full-frame, sub-sampled or
windowed 8-bit images in a wide range of formats, controlled
through the Serial Camera Control Bus (SCCB) interface.
The OV6680 operates at 30 frames per second (fps) in SGA
resolution (400x400 pixels) with complete user control over
image quality, formatting and output data. Enabling a 400x400
pixel output allows users to perform image stabilization functions
with post processing. All the required image processing functions
such as exposure control, gamma, white balance, color saturation
and hue control are also programmable through the SCCB
interface.
