Acquisition control
With Trigger OFF (free running mode), the default frame rate of the camera is based on the
specified ROI. The smaller the ROI, the faster the default frame rate. However, it is possible to
specify a free-running frame rate (i.e., no trigger needed) that is slower than the default rate.
This can be useful when a longer exposure time is needed for a specific ROI.
Modification of the frame rate is done by entering a value in the AcquisitionFrameRate control
corresponding to the frame frequency (Hz). Allowed values range from the shortest frame rate to
0.125Hz (fps), however if the value entered is less than the time required for the default frame
rate, the setting is ignored and the default frame rate is used.
The setting range in Acquisition Frame Rate is:
Calculation of the frame rate
The frame rate depends on the tap geometry and is calculated in the following formula.
Maximum Frame Rate (fps) = 1/(Rounddown
*3
([Trow]x16/C) x ([H]+E) x 0.988
*4
) x 1000000
Where,
[Trow]=Roundup
*1
((Roundup
*1
(2560 /A
*2
) x [W] /2560 + B) x A
*2
) x C /(Dx16)
If the result of the calculation is equal or less to 164, [Trow] is fixed to 164.
