In previous exercises of Python/PyQt5 GUI to control Raspberry Pi Camera using picamera2 lib , with camera_controls and White Balance , camera is assigned manually in Python code or command line argument. In this exercise (picam2_qt5_global.py), number of cameras attached and cameras info are retrieved by calling Picamera2.global_camera_info(), then run picam2_qt5_.py base on user selection. Code: picam2_qt5_global.py """ Python 3/PyQt5 + picamera2 List available cameras. Run picam2_qt5_.py base on user selection. """ from PyQt5.QtWidgets import (QComboBox, QMainWindow, QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit, QPushButton) from PyQt5.QtCore import QProcess import sys from picamera2 import Picamera2 cameras_info = Picamera2.global_camera_info() num_of_cam = len(cameras_info) if num_of_cam == 0: print("No camera attached!

It's a roughly test on Raspberry Pi 5/64-bit Raspberry Pi OS (bookworm) with Camera Module 3 (NoIR Wide and normal) .

Exercise to use the Raspberry Pi Camera in Python3/PyQt5 applications using picamera2 lib, with modification to make the preview match with captured images and enable Auto-Focus in Continuous. Tested on Raspberry Pi 5 running 64-bit Raspberry Pi OS (bookworm) with Camera Module 3. Please notice that currently only the Camera Module 3 provide Auto-Focus feature. Firstly, Copy from the example in The Raspberry Pi official manual The Picamera2 Library (2023-11-27) Charpter 8.5 Using the camera in Qt applications, named Qt_Picamera2_App.py.
