摘要

In the past, camera vendors offered analog outputs to their sensors, leaving frame-grabber manufacturers to develop high-speed camera interfaces. But as high-speed analog-to-digital converters and analog front ends become less expensive, camera manufacturers are choosing to integrate more and more functionality into their cameras. By offering digital outputs, these cameras increase the noise immunity of sensors on the factory floor, allow longer cable lengths from camera to host computers, and eliminate the need for analog PCI-based interfaces. With the move toward digital camera interfaces, camera vendors must decide whether to support point-to-point communication standards such as RS-644 and Camera Link or bus-based solutions such as IEEE-1394 and Fibre Channel.
