You can check that libcamera is working by opening a command window and typing: rpicam-hello You should see a camera preview window for about five seconds. libcamera provides a C++ API that configures the camera, then allows applications to request image frames. and the capture phase of libcamera-still). txt Just libcamera is written in C++, a language that has seen many revisions and offers an extensive set of features that are easy to abuse. With the advent of the Bookworm Pi OS the libcamera application was renamed to rpicam. 0 which combine to less than the ideal exposure setting, leading to the noisy image. You can list the cameras detected on the system with cam-l, and capture ten frames from the first camera and save them to disk with cam-c 1--capture=10--file. 1.

The output of the top command is a shell that allows the user to move through The rest of the threads are in libcamera itself, so if you are using libcamera, then you still have the overheads.
