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.

mshutter
IR-CUT (Infrared cut-off filter) is a mechanical shutter design. It is placed between the lens and the image sensor, and is controlled by a motor or an electromagnet.
IR-CUT has two status: '''Block''' or '''Deliver''' the infrared.
*Color Mode
Image is Color Mode and IR_CUT status '''Block''' infrared.
*Black&White Mode
Image is Black&White Mode and IR_CUT status '''Deliver''' infrared.
*Trigger Mode
Trigger pin : [[VEYE-MIPI-290/327|J3 pin1]].
Trigger pin High(3.3~12V),Image is Black&White Mode and IR-CUT status '''Deliver''' infrared.
Trigger pin Low(GND),Image is Color Mode and IR-CUT status '''Bolck''' infrared.
=====mshutter=====
close AE, use manual shutter
<code>./veye_mipi_i2c.sh -r -f mshutter</code>
<code>./veye_mipi_i2c.sh -w -f mshutter -p1 [value]</code>
value is exposure time（seconds）
If value is greater than or equal to 0x4B, it will reduce framerate.

Caputre mode: output the next frame each '''capture''' cmd.
=====notf=====
Requirements：hdver >= 0x3, effective in Stream mode
Number of dropped frames
It is a method of framerate control, output one frame,discard '''notf''' frames,output next frame, and so on.
''actual framerate = original framerate /（1+notf）''
For example，if the original framerate is 30fps, set '''notf''' to 2, then ''actual framerate'' is 10fps.
<code>./veye_mipi_i2c.sh -r -f notf</code>
<code>./veye_mipi_i2c.sh -w -f notf -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.
