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：

Dtoverlay

1. Open the config.txt on Raspbian:
   sudo nano /boot/config.txt

2. Add the dtoverlay into the config.txt file,
   dtoverlay=imx290,clock-frequency=74250000

3. And then press ctrl+ x to exit nad press ‘y’ to save.

4. Rebooted your Pi
   sudo reboot

5. 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.
