+After the setting is successful, you can use the camera normally.
+==== Command Line ====
+=== Control IR-Cut via V4L2 ===
+The test needs to be conducted in the framebuffer mode, and switch to the framebuffer mode through the keyboard combination of ''Ctrl''+''Alt''+''F1''.
+== Disable status ==
+```shell
+$ v4l2_test  -c 1 -p 0 -F 0 -f 0 -D 0 -R 1 -r 2 -d 2 -N 1000 -n 800 -w 0 -e 1 -I 0 -b /dev/fb0 -v /dev/video0
+```
+== Enable status ==
+```shell
+$ v4l2_test  -c 1 -p 0 -F 0 -f 0 -D 0 -R 1 -r 2 -d 2 -N 1000 -n 800 -w 0 -e 1 -I 1 -b /dev/fb0 -v /dev/video0
+```
+=== Record Video via Gstreamer ===
+```shell
+$ gst-launch-1.0 v4l2src name=vsrc device=/dev/video0 ! video/x-raw,width=1920,height=1080,framerate=60/1,format=RGB ! filesink location=.//test.rgb
+```
+The recorded video is saved in ''test.rgb''.
+==== Demo Source Code ====
+In addition to this, you can also test the camera via program.
+=== Install Dependencies ===
+```shell
+sudo apt install libopencv-dev python3-opencv
+```
+=== Python ===
+```python mipi-camera.py
+import cv2
+if __name__ == '__main__':
+    val = True
+    cap = cv2.VideoCapture(0)
+    cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
+    cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)
+    fourcc = cv2.VideoWriter_fourcc(*'XVID')
+    out = cv2.VideoWriter("./test.avi", fourcc, 20.0, (640, 480), True)
+    while val is True:
+        ret, frame = cap.read()
+        cv2.cvtColor(frame,cv2.COLOR_RGB2BGR)
+        if frame is None:
+            break
+        else:
+            out.write(frame)
+            cv2.imshow("video", frame)
+            k = cv2.waitKey(1) & 0xFF
+            if k == 27:
+                break
+    cap.release()
+    out.release()
+```
+<WRAP info >
+Please modify the number of the open camera according to the camera node.
