Description

This data brief outlines a high performance

3.15 megapixel EDOF camera module (VX6852)

for use across a range of mobile phone handsets

and accessories. It is designed to be used for high

quality still camera functions and also supports

low power video modes. The product can output

raw bayer 3 Mpixel images at up to 20 fps.

The module design is optimized for both footprint

and height. The module is always in focus from

30 cm to infinity. All components are integrated

inside the camera module, with the exception of

two CCI pull-up resistors and a de-coupling

capacitor.

VX6852 offers an ultra low power consumption

hardware standby mode consuming less than

30 µW (typ.).

A separate hardware accelerator (STV0986) or

application engine (STn8815) device can be

incorporated in the phone system to run the

associated image processing algorithms in

hardware where the baseband cannot support

this processing load. The specifications of these

devices are contained in a separate document.
