An increasing number of embedded vision applications have appeared on the market in recent years. These are systems based on an embedded computing board and a camera module. Such a system can manage vision tasks more affordably and efficiently. The interface, which is the connection between the camera module and host, plays a key role in the setup of such an embedded vision system. The plug-and-play USB 3.0 interface can be used here, for example. LVDS interfaces (Low Voltage Differential Signaling) are also worth considering, especially for FPGA-based systems. But in very many cases, the MIPI CSI-2 interface is the appropriate choice. This White Paper provides an overview of the significance and features of this important interface for the embedded vision field.
