MT9T112 – 3.1 MP Camera Module w/ Stock Lens:
The MT9T112 – 3.1 MP Camera Module Lens (B0005) is based on the MT9T112 color sensor from Micron/Aptiva. The sensor has a 1/4.0″ optical format, which combined with the pixel size of 1.75 µm x 1.75 µm, provides the 3.1 MP 2048 x 1536 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).
This adapter board does not offer a standard (M12 or CS) lens mount, but uses the “stock lens” supplied with the sensor. However, additional camera modules with similar sensors are available from ArduCAM. For example, see OV3640 – 3.0 MP Camera Module for a similar module with a bundled M12 LS-27227 lens. The MT9T112 camera is also available with just an M12 or CS lens mount and any compatible lens sold separately. Click on the Camera Lenses product category for the complete selection of ArduCAM lenses.
The key benefit of the standard lens mounts (available with the MT9D111 – 2.0 MP Camera Module, for example) is the simplicity in swapping the lens – fisheye, wide-angle, telephoto, zoom, IR or NoIR filter – all of which are available here. Be sure to note the compatible lens mount height (7 mm, 10 mm, etc) for each lens selected if you chose an M12 metal mount option. Click on the Camera Lens Mounts product category for information about lens mounts, including compatibility with the various lenses.
In the Arduino world, a “shield” is a piggy-back circuit board that provides additional functionality to the development board. In this context, a camera shield provides the required interface from the camera module to your computer. You will need create your own custom-built hardware interface via the 20-pin 0.1″ pitch connector. Or, you will need to purchase one of the available ArduCAM camera shields. You may use the ArduCAM F Shield Rev C+ or the ArduCAM LF Shield Rev C+ to connect to Arduino system boards. Open-source software and binaries are provided on the ArduCAM GitHub site (see link below) for these shields. ArduCAM supplies a wide variety of camera modules that are compatible with their USB Camera Shields, and all are available from DLSCorp.
