SinoVoip ‘s camera modules are a fabulous add-on for the BPI-M3.

There are two CMOS sensor modules, one is the OV5640 (5M pixels), the other is the OV8865 (8M pixels).

OV5640 & OV8865

module

  • Active array size: 2592×1944
  • Power supply:
    • Core: 1.5 V +/- 5% (with integrated 1.5 V regulator)
    • Analog: 2.6 ~ 3.0V (2.8V typ.)
    • I/O: 1.8V / 2.8V
  • Energy requirement:
    • Active: 140mA
    • Standby: 0.02mA

The OV8865 color image sensor is a high performance, 8 megapixel RAW image sensor that delivers 3264×2448 at 30 fps using improved OmniBSI-2TM pixel technology. It provides options for multiple resolutions while maintaining full field of view. Users can program image resolution, frame rate, image quality parameters. Camera functions are controlled using the industry standard serial camera control bus (SCCB).

The OV8865 is capable of delivering 30 fps at full resolution allowing burst photography at full 8 megapixel resolution. With a complete 8 megapixel image array, the OV8865 contains all the image management functions to ensure high quality imaging solutions for high resolution digital still camera (DSC), HD camcorders and mobile handsets.

All required image processing functions are programmable through the SCCB interface. In addition, OmniVision image sensors utilize proprietary sensor technology to improve image quality by reducing or eliminating common lighting/electrical sources of image contamination, such as fixed pattern noise, smearing, etc., to produce a clean, fully stable, color image.
