9.1. Frame Rate Calculation Tool
Figure 9-1 Frame rate calculation tool
The frame rate calculation tool is currently provided in the form of Excel. When using it, firstly select the
camera model in the table, and then achieve the expected frame rate by modifying the parameter of the
camera. There are four major types of influencing factors, including image readout time (image width,
image height, pixel format), exposure time, acquisition frame rate control, and device link throughput limit.
Table parameter explanation:
1) The Width and Height are the set ROI size.
2) For

about
BinningHorizontal,
BinningVertical,
DecimationHorizontal
and
DecimationVertical, please refer to
. These four parameters affect
the transmission time of the image data.
3) The ExposureTime is the exposure time when the camera acquires one frame of image.
4) The PixelFormat is the pixel format corresponding to the camera output image, including 8 bits, 10
bits or 12 bits.
5) The DeviceLinkThroughputLimit represents the maximum bandwidth of the image transmitted by the
camera.
6) The MaxUSBControllerThroughputLimit represents the recommended maximum transmission
bandwidth of the camera. If this value is exceeded, frame losing may occur.
7) The AcquisitionFrameRate represents the maximum value of the frame rate control when the
AcquisitionFrameRateMode is set to on, and whether the maximum value can be reached depends
on whether the camera is affected by other acquisition parameters.
