%description
Cameras are complex devices that need heavy hardware image processing operations.
Control of the processing is based on advanced algorithms that must run on a
programmable processor. This has traditionally been implemented in a dedicated
MCU in the camera, but in embedded devices algorithms have been moved to the main
CPU to save cost. Blurring the boundary between camera devices and Linux often
left the user with no other option than a vendor-specific closed-source solution.

To address this problem the Linux media community is collaborating with the
industry to develop a camera stack that is open-source-friendly while still
protecting vendor core IP. libcamera was born out of that collaboration and
offers modern camera support to Linux-based systems, including traditional Linux
distributions, ChromeOS and Android.
