The mainstream output interfaces of the endoscope camera module are mainly two types: USB and MIPI CSI-2. There are significant differences in their universality and applicable scenarios:
USB interface uses UVC (USB Video Class) protocol, has plug-and-play features, is compatible with Windows/Linux/Android systems without additional drivers, has the strongest versatility, is suitable for medical diagnostic equipment, portable testing devices and other scenarios that require rapid deployment, However, the USB 2.0 bandwidth (480Mbps) has limitations on high-definition video transmission, and the cable length is usually no more than 5 meters.
MIPI CSI-2 interface transmits differential signals, has the advantage of low power consumption and high bandwidth (up to 2.5Gbps per channel), is designed for embedded systems, requires the main controller chip to support the MIPI protocol, is used in highly integrated and space-constrained devices (such as endoscope controllers, micro-surgical robots), but has high development complexity and hardware compatibility requirements;
Specialized Interface (e.g. Antlinx) Some high-end modules (e.g. Howey OCH2B10) use manufacturer-private protocols (e.g. Antlinx) to transfer 2Gbps data with a single pair of differential lines, but they require a specific bridge chip and have limited generality, mainly for long distance transmission of customized medical devices.
Note: Video output interfaces such as HDMI and SDI are usually implemented by the back-end bridge chip and are not native interfaces of the module.
