The Raspberry Pi 5 combines the previous CSI and DSI interfaces into two dual-purpose CSI/DSI (MIPI) ports.

Configure camera

When using a Raspberry Pi camera or a third-party camera, you can modify the camera configuration according to the following table:

Camera module	File located at: /boot/firmware/config.txt
V1 Camera (OV5647)	dtoverlay=ov5647
V2 camera (IMX219)	dtoverlay=imx219
HQ Camera (IMX477)	dtoverlay=imx477
GS camera (IMX296)	dtoverlay=imx296
Camera module 3 (IMX708)	dtoverlay=imx708
IMX290 and IMX327	dtoverlay=imx290,clock-frequency=74250000 or (both modules share the IMX290 kernel driver; for the correct frequency, see the module vendor's instructions) dtoverlay=imx290,clock-frequency=37125000
IMX378 type	dtoverlay=imx378
OV9281 series	dtoverlay=ov9281

If you are not using the official Raspberry Pi camera, you can modify the config.txt file as shown in the table and add the dtoverlay content to the /boot/firmware/config.txt file.


xxxxxxxxxx
sudo nano /boot/firmware/config.txt

For example: Raspberry Pi uses IMX219 camera, connect the camera to the Raspberry Pi J4 interface, and then modify the /boot/firmware/config.txt file:


xxxxxxxxxx
To use the IMX219 camera, it needs to be connected to the J4 interface of Raspberry Pi 5 for recognition!

Modify the configuration file and restart to take effect!

Use camera

Preview camera

rpicam-hello

Entering this command in the terminal will display the preview window for about 5 seconds.

rpicam-hello -t 0

Running this command in the terminal will always display the preview window. You can use the window close button and Ctrl+C to exit!

Photograph

rpicam-jpeg -o test.jpg

Display a preview for 5 seconds, then capture the image and save it as a test.jpg file

rpicam-jpeg -o test.jpg -t 2000 --width 640 --height 480

Show a preview for 2 seconds, then capture and save the image as a test.jpg file, with the image having a width of 640 pixels and a height of 480 pixels.

rpicam-still

This command can be used to save files in different formats:


xxxxxxxxxx
rpicam-still -e png -o test.png
rpicam-still -e bmp -o test.bmp
rpicam-still -e rgb -o test.data
rpicam-still -e yuv420 -o test.data

Raw image capture


xxxxxxxxxx
rpicam-still -r -o test.jpg

Time-lapse shooting

Capture images continuously at intervals of 2 seconds for a total capture duration of 30 seconds, and save each image as a file name similar to image0001.jpg:


xxxxxxxxxx
rpicam-still -t 30000 --timelapse 2000 -o image%04d.jpg

Video

rpicam-vid

Commands for video recording using the camera module on the Raspberry Pi.

Example: Record 10 seconds of video and write to test.h264 file


xxxxxxxxxx
rpicam-vid -t 10000 -o test.h264

play video


xxxxxxxxxx
vlc test.h264

Note: If the test.h264 file cannot be played and an error occurs, please try the following method to solve it.

Error resolution

Modify the frame rate of H264 playback per second

Web page preview camera

Use Python script files to preview camera images on web pages.

Run script

Code path:/home/pi/Camera_Web_Preview/


xxxxxxxxxx
cd /home/pi/Camera_Web_Preview/
python3 mjpeg_server.py

Web access

Devices under the same LAN can enter :8000 through the browser to view the real-time camera view!


xxxxxxxxxx
Example:
Raspberry Pi IP: 10.42.0.1
Web access: 10.42.0.1:8000


xxxxxxxxxx
If you want to set up auto-start at boot, you can search for information online and set the script file to auto-start at boot!
