1 / 4 page Data Brief For further information contact your local STMicroelectronics sales office. February 2008 Rev 1 1/4 4 VB6851 QXGA camera module with auto focus Features ■ 3.15 megapixel resolution sensor (2048 x 1536) ■ Integrated auto-focus mechanism ■ High level autofocus control interface ■ 4 element lens ■ Compact size: 8.5 mm x 8.5 mm x 5.9 mm ■ Compatible with SMIA 1.0 profile 2 functional specification ■ Video data interface - CCP2.0 ■ Command interface - CCI ■ Analog power supply from 2.4 V to 2.9 V ■ Digital power supply from 1.7 V to 2.9 V ■ On-board 10 bit ADC ■ Integral EMC shielding and EMI reduction techniques ■ Ultra low power standby mode ■ Analog binning (2x2, 2x4) for low power video mode 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 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.). PC00 www.st.com |
