| **A complex camera support library for Linux, Android, and ChromeOS** |
| |
| 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 has very recently started |
| collaboration with the industry to develop a camera stack that will be |
| open-source-friendly while still protecting vendor core IP. libcamera was born |
| out of that collaboration and will offer modern camera support to Linux-based |
| systems, including traditional Linux distributions, ChromeOS and Android. |
