Open Source Summit India 2026

This session compares how camera support is built in the Zephyr Project and in the Linux kernel camera subsystem.

Zephyr focuses on real-time behavior, low memory usage, and simple system design, making it suitable for small, low-power vision devices. Linux, through frameworks such as Video4Linux2 and the Media Controller subsystem, provides a more structured and scalable approach capable of handling complex camera pipelines, multiple cameras, and advanced processing.

The session examines architectural trade offs between the two camera subsystems, comparing their design approaches and highlighting differences in driver structure, pipeline design, and overall system integration. It also explores how Zephyr’s camera architecture can evolve to support more advanced and scalable vision needs, moving closer to Linux capabilities.
