OV3640 – 3.0 MP Camera Module:
The OV3640 – 3.0 MP Camera Module is based on the OV3640 color sensor from OmniVision.
The sensor has a 1/4.0″ optical format, which combined with the pixel size of 1.75 µm x 1.75 µm, results in the 3.0 MP 2048 x 1536 VGA | WVGA | SXGA | UXGA | QXGA image. This is a rolling shutter sensor, which captures an entire column (or row) simultaneously, and compiles the image by scanning across (or down). The lens and/or sensor have an IR-cut filter, so this module is not appropriate for low-light photography. The standard lens mount for this module is the M12 mount, and ships with the LS-27227 lens. The key benefit of the standardized lens mount is the simplicity in swapping the lens – fisheye, wide-angle, telephoto, zoom, NoIR filter – all of which are available from DLSCorp. Note that this camera module can be special-ordered with either mount and any compatible lens – click on the Lenses category to see our complete selection.
Use this camera module on a Windows, Linux, or Raspberry Pi USB connection with the ArduCAM USB Camera Shield on the primary interface (a 20-pin 0.1″ / 2.54 mm pitch interface), or your custom-built interface. ArduCAM supplies a wide variety of camera modules that are compatible with the USB Camera Shield, and all are available from DLSCorp.
OmniVision CAMERACHIP™ image sensors are low voltage CMOS devices that provide the full functionality of a single-chip camera and image processor in a small footprint package. They provides full-frame, sub-sampled, scaled or windowed 8-bit/10-bit images in a wide range of formats, controlled through the Serial Camera Control Bus (SCCB) interface. All required image processing functions, including exposure control, gamma, white balance, color saturation, hue control, white pixel canceling, noise canceling, and more, are also programmable through the SCCB interface. A compression engine provides for increased processing power. In addition, OmniVision CAMERACHIP sensors use 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.
