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.

Stream mode:  stream output

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.
 +
 +
=====csienable=====

宽动态模式下的整体亮度目标值。
 +
 +
WDR模式生效,[0-0xFF]默认值0x80,WDR模式下,值越大,亮度越高。
 +
 +
=====wdrbtargetbr=====

<code>./veye_mipi_i2c.sh -r -f wdrbtargetbr</code>
 +

<code>./veye_mipi_i2c.sh -w -f wdrbtargetbr -p1 0x80</code>
 +
 +
宽动态模式下的亮区亮度目标值。
 +
 +
WDR模式生效,[0-0xFF],默认值为0x30,值越大,亮区越亮。
 +
 +
此参数的效果与实际场景有关,会存在一个[0-X]的无效区,X与实际场景有关。
 +
 +
并不是说调整为0,则亮区会变黑。
