OV2640 – 2.0 MP Mini Module Camera Shield:
The ArduCAM OV2640 – 2.0 MP Mini Module Camera Shield (B0067) features the OV2640 color sensor from OmniVision. The sensor has a 1/4.0″ optical format, which combined with the pixel size of 2.2 µm x 2.2 µm, provides the 2.0 MP 1600 x 1200 UXGA 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 camera module is supplementary in order to fulfill the demands for different lens mount, field of view (FOV) and depth of the field (DOF). With the same sensor, other choices include the OV2640 Sensor with a stock lens directly attached to the sensor with an IR filter (no changes are available) and the OmniVision SCCB Camera Adapter Board (bundled as the OV2640A 2.0 MP Standalone SCCB Camera w/ Adapter Board). The OV2640 2.0 MP Camera Module (which uses the ArduCAM USB Camera Shield) is another option. Also, see the ArduCAM Mini Multi-Camera Adapter Board and ArduCAM OV5642 5.0 MP Mini Module.
Lens / Mounts:
The bundled camera module include the M12 LS-4011 (IR) lens or M12 LS-27227 (NoIR) lens and plastic mount. They are also available with just a generic plastic lens mount to protect the sensor during shipping. They may also be purchased without a lens, but with a higher quality metal M12 or CS lens mount, or they may be configured with a motorized IR cutoff filter mount; for the motorized IR cutoff filter mount, the user must supply the 5-18 V power.
The key benefit of the standard lens mounts available with this module is the simplicity in swapping the lens – fisheye, wide-angle, telephoto, zoom, IR or NoIR filter – all of which are available here – click on the Camera Lenses product category for the complete selection of ArduCAM lenses. Be sure to note the compatible lens mount height (7 mm, 10 mm, etc.) for each lens selected. Each lens purchased separately comes with an appropriate height lens mount (plastic for M12, metal for CS). 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. This is an optimized version of the ArduCAM F Shield Rev V2, which reduces the complexity of the camera control interface. It integrates the 2.0 MP CMOS image sensor OV2640, which provides miniature size as well as the easy to use hardware interface and open source code library.
The ArduCAM Mini is easily connected to standard Arduino boards, but it can also be used with any platform, like Raspberry Pi, Maple, chipKIT, BeagleBone Black, as long as they have SPI and I2C interfaces. The ArduCAM Mini not only offers the capability to add a camera interface which isn’t available with some low cost microcontrollers, but also provides the capability to add multiple cameras to a single microcontroller.
