Description
This databrief outlines a high performance
3.15 megapixel auto-focus camera module
(VB6851) for use across a range of mobile phone
handsets and accessories. It is designed to be
used for both high quality stills capture and video
modes. The module is SMIA 1.0 profile 2
compatible and is capable of generating raw
bayer 3 MP images up to 20 fps. The VB6851
supports the CCI control and CCP 2.0 data
interfaces.
As different phone platforms have different
baseband processors with varying capabilities, it
may not be possible for all phones to support the
associated image processing and auto-focus
algorithms. Where the baseband cannot support
this processing load, a separate hardware
PC00
accelerator (e.g. STV0986 ) or application engine
(e.g. STn8815) device can be incorporated in the
phone system to run the algorithms in hardware.
The specifications of these devices are contained
in a separate document.
The module design is optimized for both footprint
and height. The auto-focus mechanism combined
with a multi-element lens provides excellent
image quality at focus distances from less than
10 cm to infinity. All external components,
including the auto-focus actuator drivers, are
integrated inside the camera module, apart from
two CCI pull-up resistors.
VB6851 offers an ultra low power consumption
hardware standby mode consuming less than
30 µW (typ.).
