This article describes the differences customers can expect when comparing the Firefly camera with the Blackfly S camera.
NOTE: this article does not include the features of the deep learning version of the Firefly camera.
What is the Firefly?
The Firefly camera family is a highly compact, low-power consumption machine vision camera. Lighter and smaller than any of our other machine vision cameras, it takes advantage of the Movidius Myriad2 hardware to achieve a form factor previously unheard of, all the while maintaining the core functionality of a machine vision, GenIcam camera.
The Firefly camera runs on Spinnaker, just like our Blackfly S and Oryx cameras. It maintains the core feature set for GenIcam cameras.
Users accustomed to programming/using our Blackfly S cameras can expect a smooth transition when moving over to the Firefly camera.
Similar to Blackfly S, it can also be used on any third-party application that supports GenIcam and USB3 vision, such as Matrox, Halcon, NI Max/Labview, and others.
Differences between Firefly and Blackfly S
Due to the limitations of using a Movidius VPU versus a traditional FPGA, certain more advanced features are not available on the Firefly camera, including:
- Sequencer Control
- Color Transformation Control
- Flat Field Correction Control
- Counter and Timer Control
- Logic Block Control
- Acquisition Control --> Burst Frame nodes
- Acquisition Control --> Trigger Delay nodes
- Acquisition Control --> Trigger Activation does not have “any edge” enum entry
- Analog Control --> Balance Ratio, Balance white auto nodes
- Analog Control --> Sharpening Auto/Threshold nodes
- Device Control --> Device Scan Type node
- Device Control --> Power Supply nodes
- Transport Layer Control --> USB3 Vision --> Link Error Count/Recovery Count nodes
- Auto Algorithm Control --> ROI nodes (ROI Selector, enable, offset, width/height)
- Auto Algorithm Control --> White Balance Auto nodes (white balance auto profile, lower limit, upper limit, damping)
- Auto Algorithm Control --> Metering Mode node
- Auto Algorithm Control --> EV Compensation node
- Defective Pixel Correction --> Defect Table Factory Reset node
- Chunk Data Control --> Chunk Selector node does not have Exposure End Line status all enum entry (as well as Image CRC, Sequencer set active, Serial Data)
- Chunk Data Control --> Image CRC, Sequencer Set Active, exposure end line status all nodes
- LUT Control --> LUT Value All node
- Digital IO Control --> Input Filter Selector node
- Digital IO Control --> Line Filter Width, Line Format nodes
- Digital IO Control --> User Output nodes
- Digital IO Control --> Line Source does not have user output/counter/logic block enum entries
- Serial Port Control --> Serial Port Stop Bits does not have "Bits 1.5" enum entry
The Firefly camera has different pin functionality when comparing to the cased Blackfly S cameras. It is extremely similar to the board level Blackfly S cameras; they even share the same GPIO connector. The connector is a JST BM06B-NSHSS-TBT (LF)(SN), the mating connector is a JST NSHR-06V-S.
The Firefly does not have any opto-isolated input/output pins available; however, it does have 4 non-opto input/output pins. This allows for additional trigger/strobe outputs without needing an external power supply.
