Acquisition control (change the frame rate)

7.1.1

Acquisition control

With Trigger OFF and in 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 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 frequency to be allocated to each frame period. Allowed values range from the
frequency required for the default frame rate to a maximum of 0.125Hz (8 seconds).
The setting range is:
The shortest
Inverse number of time
required to drive all pixels in
the area set by ROI command
inverse number of time
required to transmit one
frame data
Note:
1. If the trigger is set to ON, this function is not available.
2. The value for setting is the frequency (Hz).
3. The minimum interval of a frame depends on reading out time. If the setting value is less than
time required for the minimum period, this setting is ignored and camera automatically operates
at the minimum period (frequency).
Self-running (Trigger OFF) works under the following conditions.
Exposure Mode: OFF
Exposure Mode: Timed and Frame start OFF
Exposure mode: Trigger width and Frame start OFF.

Note: When the link configuration is changed, it will take a maximum of 10 seconds. While changing
the link configuration, the camera LED lights in amber and after changed, it will turn to green.
