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 of VEYE-MIPI-327 or J2 pin1 of VEYE-MIPI-IMX327S.

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.

5.11 ircutdir

./veye_mipi_i2c.sh -r -f ircutdir

5.14 cameramode

Requirements：hdver >= 0x3

./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.

5.15 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.

./veye_mipi_i2c.sh -r -f nodf

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

ntof range is [0-0xFF]， default 0.

5.16 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.

5.17 csienable

Requirements：hdver >= 0x3

./veye_mipi_i2c.sh -r -f csienable

6 新功能

下面的新功能，只有摄像机固件版本的release time晚于2022-11-22的版本才支持。

6.1 paramsave

./veye_mipi_i2c.sh -w -f paramsave

保存isp相关参数到flash中。

6.2 new_expmode

./veye_mipi_i2c.sh -r -f new_expmode

./veye_mipi_i2c.sh -w -f new_expmode -p1 [0/1]

新版本手动曝光是否使能。

如果使能新版本手动曝光，则：

  1. 原来的mshutter命令不再生效，new_mshutter生效。
  2. 增益（agc）由自动模式也改为手动模式，new_mgain生效。
6.3 new_mshutter

./veye_mipi_i2c.sh -r -f new_mshutter

./veye_mipi_i2c.sh -w -f new_mshutter -p1 1000

新版本手动曝光时间配置，单位为us，范围是[1,1000000].

由于sensor无法支持精确到1us的曝光时间，建议在配置之后，读取一下进行确认。

6.4 new_mgain

./veye_mipi_i2c.sh -r -f new_mgain

./veye_mipi_i2c.sh -w -f new_mgain -p1 2.1

新版本手动增益，根据sensor不同，精确到0.1dB或者0.3dB。

6.5 auto_shutter_max

此功能只有release time晚于2022-12-09的版本才支持。

在mshutter配置为auto时，配置自动曝光的上限。

./veye_mipi_i2c.sh -r -f auto_shutter_max

./veye_mipi_i2c.sh -w -f auto_shutter_max -p1 1000

单位为us，范围是[1,1000000/fps].

由于sensor无法支持精确到1us的曝光时间，建议在配置之后，读取一下进行确认。
