Camera serial interfaces interconnect the camera in a device to the application processor or image signal processor. MIPI Alliance offers two camera and imaging interfaces, MIPI CSI-2 and MIPI CSI-3.

MIPI CSI-2 operates on the MIPI C-PHY and/or MIPI D-PHY physical layers. MIPI CSI-3 operates on the MIPI UniPro transport layer using the MIPI M-PHY physical layer. Each can be used to bring high-resolution imaging, rich color and advanced video capabilities to smartphones, tablets, automobiles, video game devices, camera drones, wearables and other products.

MIPI CSI-2 and MIPI CSI-3 are developed by the MIPI Camera Working Group.
