MIPI CSI-2

MIPI CSI-2 相机接口Advanced

A high-speed serial interface standard that carries image data from a camera sensor to a processor.

MIPI CSI-2 is a camera serial interface specification defined by the MIPI Alliance (Mobile Industry Processor Interface Alliance) that specifies how an image sensor sends raw pixel data to a processor — an SoC, or system-on-chip — at high speed. Nearly every phone camera uses it, and embedded boards such as NVIDIA’s Jetson and the Raspberry Pi also expose CSI ports. It has low latency and low power draw, and can connect directly into a chip’s onboard ISP (image signal processor). Its cable runs are short, however, so when a robot’s or car’s camera sits far from the main compute unit, the signal is typically extended over longer distances with serializers such as GMSL (Gigabit Multimedia Serial Link).

ExampleA CSI camera module is wired to a Jetson Orin dev board with a ribbon cable, feeding images straight into the board’s onboard ISP.
