=====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.
 +
 +
<code>./veye_mipi_i2c.sh -r -f nodf</code>

=====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.

1 介绍

目录下总共4个文件，camera_i2c_config、i2c_read、i2c_write、veye_mipi_i2c.sh。

第一次使用需要确认此目录下文件都具备可执行权限。

你需要先运行camera_i2c_config

./enable_i2c_vc.sh

./camera_i2c_config

配置管脚，然后执行veye_mipi_i2c.sh

2.1 camera_i2c_config USAGE

连接树莓派Computer Module情况下，运行

./camera_i2c_config [cameranum]

cameranum description

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.

./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.
