I picked up the new Raspberry Pi High Quality camera last week. It’s pretty impressive. In this article, I’ll show you some ways to interact with this camera and do some cool stuff with it. This is my current setup for this article. I built little stage with Mario, and I have the camera with a lens, into my Pi, and a temp/humidity sensor hooked to it. It’s the same I used in my . previous live stream with this camera In this article, we’ll learn: How to set up Raspberry Pi High Quality Camera How to configure the camera with V4L2 Take pictures with Raspistill Record video with Raspivid About the Raspberry Pi HQ Camera So this camera has some pretty impressive specs for the price. Sony IMX477R stacked, back-illuminated sensor, 12.3 megapixels, 7.9 mm sensor - diagonal, 1.55 μm × 1.55 μm pixel size Output: RAW12/10/8, COMP8 Back focus: Adjustable (12.5 mm–22.4 mm) Lens standards: C-mount, CS-mount (C-CS adapter included) IR cut filter: Integrated Ribbon cable length: 200 mm Tripod mount: 1/4”- 20 It’s a 12MP camera with a decent sensor. Far better than previous Raspberry Pi Cameras. It comes with a ribbon, and a sensor cap out of the box. However you will need to provide a lens for it (C or CS Mount.) You can get . I chose , it’s not too shabby and only 33 dollars. I also had an old cell phone tripod lying around so I mounted the camera to it. your own HQ Camera here this 35mm lens for the camera Assembly is pretty straightforward. So enough about the camera, let’s look at how to use it. Configure the Camera First, you’ll need to open up your Raspberry Pi Configuration: In the configuration, enable “Camera”: And reboot your Pi. Dialing in the Camera If you want to know right away the camera is working, get qv4l2. This is the V3L2 Test Bench. It will help you get your camera into focus, and you can change various settings. sudo apt-get install qv4l2 After installing it you’ll need to load this into your kernel: sudo modprobe bcm2835-qv4l2 Then run the program: qv4l2 This application will give you a realtime view of your camera: This will help you focus the lens and adjust your lighting, contrast, etc. Pro tip: You can adjust the base focal length of the lens with the camera. You can adjust back and forth depending on what subject you’re focusing on then set it with a set screw. This will make it easier to get the camera focused in. With this, I just used a laptop to view the live preview, so I could make adjustments and fine-tune the lens focus. Once you dial it in, you can start taking some pictures! Capture Images with Raspistill The easiest way to test this camera is by using Raspistill. It’s available by default in Raspberry Pi OS/Buster. Its usage is simple: raspistill -o test.jpg This will output a high res image like this one: Which is exactly what we were looking at with the V4L2 capture. Here are just a few things we can do with Raspistill: Change the size and quality of the image Set exposure/ISO other settings RAW mode output Type in “raspistill” by itself to see the options. Let’s try to add the date and time to our image. We’ll set it to a 1024 x 768 image while we’re at it: raspistill -n -t -w -h -a -ae + + -o test2.jpg 1000 1024 768 1036 25 25 So one thing that Raspistill doesn’t allow is free form annotation or adding any text I want to the image. With Raspistill, you can take still pictures with the camera, and they look great. There are many things you could do with this, including: - Take one picture a minute, and rotate out after a couple of hours Security camera - take pictures every minute and upload it to a web page, like the old webcams of the 90s Webcam - you could set up a motion detector and have it take pictures and store them when motion is present. Motion detection There are many cool things you could do with Raspistill. Let’s look at video! Record Video with Raspivid Raspivid is another cool application for interacting with the Raspberry Pi Camera Module. It’s a similar interface as Raspistill, and it’s pretty easy to use. Here’s how you can record ten seconds of video: raspivid -t -o test.h264 10000 You can do lots with this program as well, including changing bitrate, levels, and just about anything you can think of. Here’s an example of the resolution far away, if you wanted to use this as a security camera: You can even record out in something like MP4. From the Raspberry Pi documentation: You can install MP4 box: sudo apt install -y gpac Then raspivid -t 30000 -w 640 -h 480 -fps 25 -b 1200000 -p 0,0,640,480 -o pivideo.h264 MP4Box -add pivideo.h264 pivideo.mp4 rm pivideo.h264 # Capture 30 seconds of raw video at 640x480 and 150kB/s bit rate into a pivideo.h264 file: # Wrap the raw video with an MP4 container: # Remove the source raw file, leaving the remaining pivideo.mp4 file to play This produces a nice little MP4 file: It’s easy and simple to convert. Final Thoughts There are many things you can do with this camera, and I plan to expand on it a lot more. My takeaways: I like the interchangeable lenses Excellent image/video quality for the price Easy to work with So if you’re thinking about picking one up, I’d highly recommend it. There are a ton of great projects you can do with this.
