Maximum Allowed Frame Rate
In general, the maximum allowed acquisition frame rate on the camera may be limited by several factors:
The amount of time that it takes to transmit an acquired frame from the camera to your computer.
The amount of time needed to transmit a frame depends on the bandwidth assigned to the camera.
The setting for the Sensor Digitization Taps parameter. If this parameter is set for Two taps, you will be
able to acquire frames at a higher rate than if it is set to One tap.
The Binning feature. If binning is enabled, the maximum allowed frame rate will increase.
The amount of time it takes to read an acquired frame out of the imaging sensor and into the camera's
frame buffer. This time varies depending on the setting for the Height parameter. Frames with a smaller
height take less time to read out of the sensor. The frame height is determined by the camera's Height
settings (Image Format Control).
The exposure time for acquired frames. If you use very long exposure times, you can acquire fewer frames
per second.
Decreasing the Height parameter can increase the maximum allowed frame rate; however
the Width parameter does not affect the frame rate.
When the camera's Acquisition Mode is set to Single Frame, the maximum possible
acquisition frame rate for a given ROI cannot be achieved. This is true because the camera
performs a complete internal setup cycle for each single frame and because it cannot be
operated with Trigger Overlap – Readout mode.
To achieve the maximum possible acquisition frame rate, set the Acquisition Mode
parameter to Continuous and the Trigger Overlap parameter to Readout.
