12MP IMX477 Motorized Focus Camera Module

Introduction

This Arducam IMX477 High Quality motorized focus camera module integrates a motor that could be controlled by software for a smarter focus, and you will no longer focus the camera by screwing the lens with your bare hands.
So how has software focus control made it more convenient? Here is an idea: Arducam provides you with an example program to control the focusing motor with keyboard keys, so you can focus the camera remotely with precision in an intuitive way. In another example powered by OpenCV, algorithms are used to control the motor and achieve autofocus.
Other than its motorized focus, it offers the same picture quality and camera controls as the Raspberry Pi High Quality camera.

Quick Start Guide

For Bullseye System

If you are running the latest version of Raspberry Pi OS. (January 28th，2022 or later releases, Debian version:11(Bullseye)). You need to update the config file and use libcamera apps.

• For Raspberry Bullseye users running on Pi 4, please do the following:

sudo nano /boot/config.txt 
Find the line: camera_auto_detect=1, update it to:
camera_auto_detect=0
dtoverlay=imx477
Save and reboot.

• For Bullseye users running on Pi 0 ~ 3, please also: 

Open a terminal 
Run sudo raspi-config
Navigate to Advanced Options 
Enable Glamor graphic acceleration 
Reboot your Pi

If you encounter the display issues, please also execute the following steps:

Open a terminal
Run sudo raspi-config
Navigate to Advanced Options
Navigate to GL Driver
Select GL (Full KMS)
Reboot your Pi

• For Raspberry Pi Compute Module 3/4

The latest software only supports one camera at this time, CM4 uses CAM1 by default.

If you are running the previous systems (Buster legacy and the system before it), you can refer to the following steps:

For Legacy System

Hardware Setup

First Use

1.Clone the file

git clone https://github.com/ArduCAM/RaspberryPi.git

2.Install Python Dependency libraries

sudo apt-get install python-opencv 

3.Enable the I2C0 adapter

cd RaspberryPi/Motorized_Focus_Camera
chmod +x enable_i2c_vc.sh
./enable_i2c_vc.sh

Then press ‘y’ to reboot.

4.Demo code

4.1 Motorized_Focus_Camera_Preview.py

This demo supports focusing in preview mode. Single focus by keyboard up and down arrow.

cd RaspberryPi/Motorized_Focus_Camera
sudo python Motorized_Focus_Camera_Preview.py

4.2 Motorized_Focus_Camera_Snapshot.py​​​

This demo supports focusing and save the image to the local filesystem. You can save the image after each focus. Single focus by keyboard up and down arrow.

cd RaspberryPi/Motorized_Focus_Camera
sudo python Motorized_Focus_Camera_Snapshot.py

4.3 Autofocus.py

This demo supports auto focusing in preview mode.

cd RaspberryPi/Motorized_Focus_Camera
sudo python Autofocus.py
