The slow shutter mode is usually used to reduce picture noise in low-illumination scenes by automatic frame reduction.
The slow shutter mode is usually used to reduce picture noise in low-illumination scenes by automatic frame reduction.
It needs to be used with the '''aetime''' parameter.<br />
It needs to be used with the '''aetime,slowshuttergain''' parameter.
=====slowshuttergain=====
<code>./cs_mipi_i2c.sh -w -f slowshuttergain -p1 X -p2 Y</code>
<code>./cs_mipi_i2c.sh -r -f slowshuttergain</code>
In slow shutter mode,the threshold of Gain be begin to drop frame, dB. Effective when '''expfrmmode''' is slow shutter mode.
X is the integer part and Y is the decimal part, for example X is 2 and Y is 3 means 2.3dB.
X range: depending on sensor.
Y range: [0-9].<br />
