OV7251 – 0.3 MP Monochrome Global Shutter MIPI Camera Module
The OV7251 – 0.3 MP Monochrome Global Shutter MIPI Camera Module is based on the OV7251 monochrome sensor from OmniVision. The sensor has a 1/7.5″ optical format, which combined with the pixel size of 3.0 µm x 3.0 µm, provides the 0.3 MP 640 x 480 SXGA image. What makes this module unique is the global shutter feature. This records every pixel simultaneously, not sequentially as with most (rolling shutter) sensors; as a result, the OV7251 produces a higher quality image. In addition, this camera uses a 1-lane MIPI interface. In the default mode, the OV7251 sends out a full-resolution image at 100 frames per second (fps) as 10-bit raw data. The OV7251 also provides flexibility for configuring frame size, exposure, gain, and other parameters.
Lens / Mounts:
The lens is a stock lens with an Effective Focal Length of 1.3 mm, and f/2.2 – it is well suited to a range of applications as its focus range is 65 mm to infinity.
Raspberry Pi Interface:
This MIPI camera replaces the similar parallel interface camera (B0128) that used the ArduCAM MIPI Adapter Board for USB3.0 Camera Shield and the ArduCAM USB3.0 Camera Shield through its secondary interface (a 30-pin 0.5 mm pitch interface). This new camera module is a custom-designed plug-in for the Raspberry Pi system boards. The board itself is tiny, at around 40 mm x 40 mm. The camera is connected to the BCM2835 processor on the Pi via the CSI bus. The CSI bus is capable of extremely high data rates, and it carries pixel data exclusively. A 15-pin flexible flat cable (FFC) connects the camera to the CSI socket on the Raspberry Pi; additional lengths of the FFC cables are also available.
The camera is supported in the latest version of Raspbian, Raspberry Pi’s preferred operating system.
