General
- CAM-MIPI327RAW is a low-cost fisheye Lens excellent low illumination and wide dynamic camera module, designed for whole series Raspberry(P4/Pi3B+/PI3A+/PI3/CM3/CM3+). Plug into the CSI-2 Pi camera interface directly.
- On-board IMX327LQR-C is a diagonal 6.46 mm (Type 1/2.8) CMOS active pixel type solid-state image sensor with a square pixel array and 2.13 M effective pixels. This chip operates with analog 2.9 V, digital 1.2 V, and interface 1.8 V triple power supply, and has low power consumption. High sensitivity, low dark current and no smear are achieved through the adoption of R, G and B primary color mosaic filters. This chip features an electronic shutter with variable charge integration time.

Using Raspbian Build-In Driver
Load Raspberry Pi image
Prepare a capacity of more than 8GB TF card(16Gb Class10 is better) and a card reader. Load the image file on to the SD card, using the instructions provided on the Raspberry Pi website for Linux,
Mac or PC:
https://www.raspberrypi.org/documentation/installation/installing-images/README.md
Raspbian Image download:
https://www.raspberrypi.org/downloads/
Driver Sources Codes
The existing IMX290 driver and overlay also work fine with IMX327 and IMX426.
The open source driver on Raspbian:
https://github.com/raspberrypi/linux/blob/rpi-5.10.y/drivers/media/i2c/imx290.c
Reference codes：
https://github.com/torvalds/linux/blob/master/drivers/media/i2c/imx290.c
Dtoverlay
- Open the config.txt on Raspbian:
sudo nano /boot/config.txt
- Add the dtoverlay into the config.txt file,
dtoverlay=imx290,clock-frequency=74250000
- And then press ctrl+ x to exit nad press ‘y’ to save.
- Rebooted your Pi
sudo reboot - Use below command to check the camera is ready.
ls /dev/video0

Libcamera On Raspbian
libcamera is an open-source Linux community project. More information is available at the libcamera website: https://libcamera.org/
The libcamera source code can be found and checked out from the official libcamera repository. https://git.linuxtv.org/libcamera.git/
When running a Raspberry Pi OS based on Bullseye, the 5 basic libcamera-apps are already installed. In this case, official Raspberry Pi cameras will also be detected and enabled automatically. Below we only take ‘libcamera-hello’ for example. For more information, please refer to below link：
https://www.raspberrypi.com/documentation/accessories/camera.html#binary-packages
In addition, Below test base on Raspberry Pi 4, If you want libcamera apps on Bullseye running on Pi 0 – 3, please refer to below link:

Libcamera-hello
libcamera-hello is the equivalent of a “hello world” application for the camera. It starts the camera, displays a preview window.
Preview
Use below command to start the preview. libcamera-hello -t 10000
Set the Frame Rate
The IMX327 modue can support up 60fps.

libcamera-hello –framerate 60
Set the Bit-Depth
libcamera-hello -t 10000 –mode 1920:1080:12:U
Above command set IMX327 work on 12bit , 1920(W) * 1080(H) unpacked mode. For more detail –mode arg : Camera mode as W:H:bit-depth:packing, where packing is P (packed) or U(unpacked)
