7.1.2
Acquisition frame rate
With Trigger OFF, which is free-running operation, it is possible to set a longer acquisition period
than the time required to read out all pixels in the area set by the ROI command.
The setting is done in the acquisition frame rate.
The setting range is:
Shortest
The reciprocal of the time
required to read out all
pixels in the area set by ROI
The reciprocal of the time 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 frame frequency (Hz).
3. If the setting value is less than the minimum period, this setting is
ignored and camera operates at the minimum period.
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.

Calculation of frame rate
In the following formula, the underlined results should be rounded up.
7.1.4.1
V Binning Off
The frame rate is the smaller of the Sensor frame rate or the Network frame rate.
Sensor frame rate(Hz) = 1000000/〔 ［ Height/2 + {((720-(Height/2)-1)/4} + 25 ］x
OR
Network_Frame_Rate(Hz) = Network_Bit_Rate / [{(Width × Height × BitsPerPixel / 8)
Note1: The network bit rate is;
1000000000 for Single
2000000000 for LAG
Maximum guaranteed bandwidth is 93% (0.93) of this value
Note2: The bit per pixel value is the number of bits associated with the selected pixel
format
