7. Operating modes
The following controls are related to capturing the image.
7.1. Acquisition control (change the frame rate)
7.1.1 Acquisition frame rate
With Trigger OFF (free running mode – see section 7.2.1), 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.
To change the frame rate, the user may modify the default value which is displayed in the
AcquisitionFrameRate control based on the ROI specified. The user can type a number
corresponding to the desired frame rate or move the slider control to the appropriate value.
Allowed values range from the ROI’s default fastest frame rate to a rate of 0.125 frames
per second (8 seconds per frame). If the value entered is faster than the default frame rate,
the setting is ignored and the default frame rate is used
The setting range in Acquisition Frame Rate is:
