As modern vehicles shift toward the Software-Defined Vehicle (SDV) paradigm, the automotive industry demands low-latency, highly secure vision systems for Advanced Driver Assistance Systems (ADAS), automated driving, and Exterior View Systems (EVS) like 360-degree surround-view parking and digital mirrors. This article provides an in-depth exploration of the QCarCam API, its architecture, core functionality, cross-VM operations, and functional safety compliance. 1. Architectural Overview of QCarCam
