64MP OwlSight¶

Introduction¶

Arducam has released the highly influential and industry benchmark Arducam 64MP Hawkeye autofocus embedded camera for Raspberry Pi platform in 2022. Since the product was released, it has been widely praised. However, the camera, which is completely based on Arducam's independent research and development, cannot be natively supported by the Raspberry Pi platform. Users need to download the corresponding driver installation package to drive and use the camera.

Now, Arducam is coming with the latest Arducam 64MP OwlSight OV64A40 autofocus camera module. The biggest feature of the new 64MP OV64A40 OwlSight camera is that it will be fully supported by the mainstream software: libcamera apps.

In addition, we have created a complete ecosystem for it, with accessories, products, and solutions available, which will greatly save you the energy and time spent in developing and implementing projects. We also support a deeper freedom in customization. You can share any of your ideas with us, and we will use our expertise and services to help you realize any project.

Highlight Features¶

Highlight Features
+ Native Supported by libcamera: Raspberry Pi mainstream software libcamera directly drives the camera, eliminating the need to install the camera driver and simplifying user access.
+ Ultra-high resolution: ultra-clear picture quality, maximum resolution 9248x 6944 (64MP).
+ Excellent photosensitive performance: larger optic format (1/1.32). The largest pixel size among sensors of the same level.
+ Higher frame rate: Higher frame rate can still be obtained at high resolution. (Sensor Max Frame Rate: 9248x6944@15fps).
+ Dual mode Focus: CDAF Autofocus & software control manual focus.
+ Rich peripheral accessories: one-stop supporting parts and the overall industry ecosystem. From modules -> products -> solutions.

Please keep the kernel up-to-date and restart after updating.

sudo apt-get update
sudo apt-get upgrade

Supported Raspberry Pi OS

Raspberry Pi Bookworm OS

Supported Raspberry Pi Kernel Version

Info

Please do not update the kernel to a non-stable version, such as via sudo rpi-update:

6.1.73 and later version

You can check your kernel version by:

uname -v | grep -oP '\d+\.\d+\.\d+'

Supported Raspberry Pi platforms(All tested)

Raspberry Pi 5/Raspberry Pi 4/Raspberry Pi 3

Enable the camera driver

¶

Step 1. Open and edit the config file

sudo nano /boot/firmware/config.txt

Step 2. Add dtoverlay to enable the OwlSight camera

Note

Arducam OV64A40 camera supports adjusting the image speed (link-freq parameter under config.txt).

There are currently two speeds: 360000000 and 456000000

Option 1. If you want to choose link-freq 360000000, you need to add the sentence below under [all] in the config file:

dtoverlay=ov64a40,link-frequency=360000000
camera_auto_detect=0

The cam1 port is enabled on Pi 5 by default. If you want to enable the camera on the cam0 port of Pi5, please refer to the following modifications:

sudo nano /boot/firmware/config.txt 
#Find the line: [all], add the following item under it:
dtoverlay=ov64a40,cam0,link-frequency=360000000
#Save and reboot.

Option 2. If you want to choose link-freq 456000000, you need to add the sentence below under [all] in the config file:

dtoverlay=ov64a40,link-frequency=456000000
camera_auto_detect=0

The cam1 port is enabled on Pi 5 by default. If you want to enable the camera on the cam0 port of Pi5, please refer to the following modifications:

sudo nano /boot/firmware/config.txt 
#Find the line: [all], add the following item under it:
dtoverlay=ov64a40,cam0,link-frequency=456000000
#Save and reboot.

Warning

Please make sure you have only one dtoverlay sentence enabled in your config file, either 360000000 or 456000000.
If both dtoverlay sentences are enabled in your config file,there will be a conflict.
In addition, When link-frequency=456000000 is settled, the camera extension solution may have data transfer issues. Only a single camera can be used at this time. Please also ensure that the length of the flexible cable is short.

Step 3. Reboot to take effect

Please reboot your Pi when you finish the installation.

sudo reboot

Step4. Use rpicam to access Arducam 64MP Camera

Preview 5 seconds.

rpicam-still -t 5000

If you don't have a display screen, you can save an image without displaying it. And an image of test.jpg will be saved in the current directory.

rpicam-still -t 5000 -n -o test.jpg

For more instructions, please refer to: libcamera/rpicam User Guide
