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 : 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.

3.1.10 mshutter

close AE, use manual shutter

./veye_mipi_i2c.sh -r -f mshutter

./veye_mipi_i2c.sh -w -f mshutter -p1 [value]

value值为曝光时间(单位:s)

value 大于等于0x4B则进入低帧率模式

3.1.11 cameramode

Requirements:hdver >= 0x3

./veye_mipi_i2c.sh -r -f cameramode

./veye_mipi_i2c.sh -w -f cameramode -p1 [value]

value description
0x0 Stream mode
0x1 Capture mode

Stream mode: stream output

Caputre mode: output the next frame each capture cmd.

3.1.12 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.

./veye_mipi_i2c.sh -r -f notf

./veye_mipi_i2c.sh -w -f notf -p1 [value]

ntof range is [0-0xFF], default 0.

3.1.13 capture

Requirements:hdver >= 0x3, effective in Capture mode

./veye_mipi_i2c.sh -w -f capture

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.

3.1.14 csienable

Requirements:hdver >= 0x3

./veye_mipi_i2c.sh -r -f csienable

./veye_mipi_i2c.sh -w -f csienable -p1 [value]

value description
0x0 suspend csi output
0x1 enable csi output

default: 0x1

Note: This is not low power mode, the camera is still working.

3.1.15 brightness

./veye_mipi_i2c.sh -r -f brightness

./veye_mipi_i2c.sh -w -f brightness -p1 0x32

AE的目标亮度,范围[0,0x64]

3.1.16 aespeed

./veye_mipi_i2c.sh -r -f aespeed

./veye_mipi_i2c.sh -w -f aespeed -p1 0x32

AE 调节速度,由慢到快[0,0x64]

3.1.17 contrast

./veye_mipi_i2c.sh -r -f contrast

./veye_mipi_i2c.sh -w -f contrast -p1 0x32

图像对比度,范围[0,0xFF],默认为0x80

3.1.18 saturation

./veye_mipi_i2c.sh -r -f saturation

./veye_mipi_i2c.sh -w -f saturation -p1 0x32

饱和度,范围: [0,0x64]

3.1.19 wdrbtargetbr

./veye_mipi_i2c.sh -r -f wdrtargetbr

./veye_mipi_i2c.sh -w -f wdrtargetbr -p1 0x80

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。

3.1.20 wdrbtargetbr

./veye_mipi_i2c.sh -r -f wdrbtargetbr

./veye_mipi_i2c.sh -w -f wdrbtargetbr -p1 0x80

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。
