Image Signal Processing Drivers and Upstream Merging

Explore the intricacies of Image Signal Processing (ISP) drivers and learn how to merge one upstream in this informative conference talk by Helen Koike from Collabora. Delve into the world of camera sensors, MIPI DPHY bus, and the Rockchip RK3399 ISP. Gain insights into the Rkisp1 hardware architecture and media topology, comparing it with the IPU3 Imgu offline processing. Understand the differences between inline and offline processing, auto and manual configuration propagation, and the complexities of crop and image stabilization. Discover how to set sub-rectangles and navigate complex topologies. The talk concludes with a discussion on libcamera, providing a comprehensive overview of ISP driver development and integration.
