бенчмарки Fastvideo SDKSlow Motion Camera

High speed camera for slow motion is based on monochrome or colour 10-bit CMOS sensor with optical format 1/2", resolution 640 x 480 and progressive scan. Camera provides frame rate 500 fps for full frame resolution and much more for partial scanning at reduced resolutions. One can get 1900 fps for the region of interest 320 x 240. Example applications include high-speed video inspection, particle tracking, kinematics, collision studies and biological image analysis. The camera is connected to PC via PCI-Express framegrabber with standard Camera Link interface (Base configuration), providing direct image transfer to computer memory at rates up to 255 Megabytes per second.

high speed slow motion camera 500 fpsCamera Link imaging board provides real-time interface between the camera and PCI-Express bus and insures data transfer and camera control. External power source is necessary for the camera. The camera has also trigger inputs to control data capture and strobe outputs to synchronize external equipment.

The software provides camera control and image capture. That software captures video stream at up to 500 frames per second with 640 x 480 at 8-bit resolution and provides user-selectable playback frame rates. Advanced versions of the software are available at additional charge.

Special Features of Slow Motion Camera

  • Frame rate 500 fps for full frame resolution (640 x 480, 8 bit)
  • Subsumpling in Y direction to achieve reduced resolution while maintaining the constant field of view and increased frame rate (950 fps for full frame resolution with subsumpling)
  • Randomly programmable ROI read out (implemented as scanning of lines/columns from an uploaded position)
  • High frame rate at reduced resolutions: for the region of interest 320 x 240 one can get up to 1900 fps
  • Camera data rate up to 1500 Mbit/s
  • Embedded 32-bit Risc processor
  • Read out direction can be reversed in X and Y
  • Non-destructive readout option
  • Multiple slope mode with extended dynamic range up to 90 dB
  • Full snapshot shutter (integration during read out is possible): at frame rate 500 fps (640 x 480) the exposure could be in the range from 4 µs up to 2 ms
