2.5.2 CSI Camera Interface

Raspberry Pi can use a regular USB camera, but it has a device for Pi-only camera. You can connect a dedicated camera with a short ribbon cable to the CSI camera port on the board. The CSI port is connected to the ISP (Image System Pipeline) in SoC of Raspberry Pi. ISP processes the incoming camera data and converts it into image or video. Using this camera, we use 250mA of current.
