What is CSI-2?

CSI-2 (Camera Serial Interface 2) is a technical specification for a camera interface developed by the MIPI Alliance. It is widely used to connect camera modules to host processors, particularly in mobile devices like smartphones and tablets, but also in automotive, drones, and other embedded vision systems. CSI-2 defines a high-speed serial interface for transmitting image data, control signals, and synchronization information between the camera sensor and the processing unit. It's a cost-effective and efficient standard for transferring image data with low power consumption.
