====== Preview GREY format images using opencv ======
* install opencv
<code>pip uninstall opencv-python</code>
<code>sudo apt install python3-opencv</code>
* Preview using this [https://github.com/veyeimaging/raspberrypi_v4l2/tree/main/samples/opencv/raw_camera sample]:
<code>python ./v4l2dev_2_opencv_show_grey.py --width 640 --height 480 --fps 30</code>
