Further works on my previous post Python/PyQt5/Picamera2 to control Raspberry Pi Cameras with GUI, with camera_controls , added White Balance setting. Actually, I'm not sure the setting and operation of Awb and ColourGains. refer:  ~ The Picamera2 Library document, Appendix C: Camera controls.

Follow my previous exercise  Python/PyQt5 GUI to control Raspberry Pi Camera using picamera2 lib , added function to change camera_controls for brightness at runtime. This video also show two instances run to control two cameras at the same time. Because my Camera Module 3 (with Auto-Focus) is assigned to Picamera2(1), so I make 1 as default. If you have one camera only, or you want 0 as default, set: DEFAULT_CAM_NUM = 0 picam2_qt5_2024-01-13.py """ Python 3/PyQt5 + picamera2 to control Raspberry Pi Camera Modules Tested on Raspberry Pi 5/64-bit Raspberry Pi OS (bookworm) # in my setup: # Picamera2(0) - HQ Camera # Picamera2(1) - Camera Module 3 picam2_qt5_2023-12-28.py first exercise picam2_qt5_2024-01-03.py Added Auto-Focus feature detection, and switch AF Mode between Continuous & Manual picam2_qt5_2024-01-07.py Display Preview in seperated window, both Main/Preview windows have Capture button. picam2_qt5_2024-01-13.py Add camera_controls to adjust brig...

Previous post show a simple example of  Using the Raspberry Pi Camera in Python3/PyQt5 applications using picamera2 lib , here is another exercise with more. The video show the Python/PyQt5 run on Raspberry Pi 5 with dual camera, Camera Module 3 & HQ Camera with 6mm 3MP lens . The Raspberry Pi 5 is running 64-bit Raspberry Pi OS (bookworm). Note that if picam2 = Picamera(0) to use HQ Camera, the code will report RuntimeError: Control AfMode is not advertised by libcamera . Because HQ Camera have no Auto-Focus function. picam2_qt5_2023-12-28.py """ Python 3/PyQt5 + picamera2 to control Raspberry Pi Camera Modules Tested on Raspberry Pi 5/64-bit Raspberry Pi OS (bookworm) # in my setup: # Picamera2(0) - HQ Camera # Picamera2(1) - Camera Module 3 """ import sys, platform, os from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QLabel, QWidget, QTabWidget, QVBoxLayout, QGridLayout from PyQt5.QtGui import QIcon fr...
