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

5.14 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.

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.
