Advanced Camera Control for
Raspberry Pi
PiCamera2 is a powerful Python library providing intuitive control over Raspberry Pi camera modules. Capture stunning images, record high-quality video, and build incredible computer vision applications.
About
Picamera2 is a modern Python library designed to work with the Raspberry Pi’s camera modules, replacing the older Picamera library. It is built on top of **libcamera**, which provides advanced camera controls, better performance, and compatibility with new Raspberry Pi OS updates. With Picamera2, developers can easily capture still images, record videos, and process live camera feeds in Python, making it ideal for projects ranging from simple photography to advanced computer vision.
This library offers flexible APIs for camera configuration, allowing developers to adjust resolution, frame rate, and camera controls like exposure or focus. Since it integrates smoothly with popular Python tools such as OpenCV, it is widely used in AI, robotics, and IoT projects. Picamera2 ensures that Raspberry Pi cameras remain accessible and powerful for beginners, educators, and professionals working on innovative imaging solutions.
