Triggering and GPIO

Automatic Synchronization

The Dragonfly2 has an 8-pin GPIO connector located on the back of
the camera and case. Inputs can be configured to accept an external trigger signal. Outputs can be configured to send an output signal,
strobe or PWM signal and can drive most TTL devices at approximately
10mA. The Dragonfly2 has a logic level serial port with a bandwidth
capacity of up to 115.2 Kbps.

Multiple Dragonfly2 cameras networked on the same IEEE-1394 bus are
automatically synchronized to each other. The maximum deviation between cameras is 125μs.

Region of Interest (ROI) & Pixel Binning
The Dragonfly2 supports Format_7 custom image modes such as pixel binning and region of interest (ROI) to achieve faster frame rates and higher
sensitivity. (Example below uses a DR2-BW)

Color Processing
The color Dragonfly2 features on-camera color processing and auto
white balance. Available outputs include YUV411, YUV422 and RGB. If
a reduction in the bus bandwidth is required, users can access the raw
Bayer pattern.

Auto Iris
In addition to auto-gain and auto-shutter/exposure controls, the Dragonfly2 has a DC auto-iris output. Using standard CCTV auto-iris lenses,
users can physically control the amount of light that falls onto the CCD.
This feature is particularly important in outdoor applications where the
amount of light can vary greatly.

Software

Gamma and Programmable LUT

The FlyCapture® software development kit (SDK) is included with all Point
Grey imaging products. The SDK is compatible with Microsoft Windows
and includes a camera device driver, full software library with Application
Programming Interface (API), demo programs and C/C++ example source
code. The Dragonfly2 is also compatible with many third-party software
packages from vendors such as National Instruments, Cognex, MVTec,
A&B Software, Matrox, Mathworks, and Norpix.

The digitization of the images on the camera is achieved using a 12-bit
analog to digital converter. Users can choose either an 8-bit or 16-bit
output from the camera. Gamma can be applied to12-bit data when
8-bit output is used. Lookup table support (LUT) is also available for
custom mapping of image values.

Updatable Firmware

On-Board Memory Channels

The field-programmable gate array (FPGA) chip controls all camera functionality, including exposure, resolution and frame rate, pixel binning, user
memory channels and more. It can also be updated with new functionality
in the field.

The Dragonfly2 has the ability to save and restore camera settings and
imaging parameters via on-board memory channels. This is useful for
saving default power-up settings, such as gain, shutter, video format and
frame rate, etc., that are different from the factory defaults.
