In the case of low illuminance, the camera module can prolong the exposure time and reduce the frame rate by configuring this parameter to achieve a better effect of low illuminance.
Note that it is not suitable for use in a sports scene.

value is exposure time（seconds）
If value is greater than or equal to 0x4B, it enters slow shutter mode.
If value is greater than or equal to 0x4B, it will reduce framerate.

Caputre mode: output the next frame each '''capture''' cmd.
=====nodf=====
Requirements：hdver >= 0x3, effective in Stream mode
Number of dropped frames
It is a method of framerate control, output one frame,discard '''nodf''' frames,output next frame, and so on.
''actual framerate = original framerate /（1+nodf）''
For example，if the original framerate is 30fps, set '''nodf''' to 2, then ''actual framerate'' is 10fps.
<code>./veye_mipi_i2c.sh -r -f nodf</code>
<code>./veye_mipi_i2c.sh -w -f nodf -p1 [value]</code>
'''ntof''' range is [0-0xFF]， default 0.
=====capture=====
Requirements：hdver >= 0x3, effective in Capture mode
<code>./veye_mipi_i2c.sh -w -f capture</code>
Output the next frame. This cmd does not interfere the sensor, it just output the next frame (the newest frame).
So it is not trigger mode, there will be a delay[0,1/framerate] between the cmd and the frame exposure.
It is applicable to those that do not require a high level of real-time performance.
=====csienable=====
