OV7675 – 0.3 MP Camera Module:
The OV7675 – 0.3 MP Camera Module is based on the OV7675 color sensor from OmniVision. The sensor has a 1/9.0″ optical format, which combined with the pixel size of 2.5 µm x 2.5 µm, provides the 0.3 MP 640 x 480 VGA 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 cutoff filter, so this module is not suitable for IR photography.
Lens / Mounts:
This module does not have a lens mount, but relies on the stock lens supplied with the sensor.
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 may choose to create your own custom-built hardware interface via the 20-pin 0.1″ / 2.54 mm pitch interface. Or, you will need to purchase one of the available ArduCAM camera shields. The ArduCAM USB Camera Shield provides you a USB connection to a Windows, Linux, or Raspberry Pi computer for these camera modules. 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.
