Once you have chosen a camera, the video signal from it needs to be connected to a computer. This is accomplished by using a frame grabber or a direct digital interface, Many video output standards are available today. The choices include several analog standards (RS-170, CCIR, NTSC, PAL, Interlaced, Progressive Scan, S-Video and some non-standard formats), as well as serial and parallel digital interfaces (Firewire, Camerlink, GigEthernet, Parallel Digital and others). The frame grabber takes care of properly formatting the video signal coming from the camera (or any other video source), so it can be further processed in software. In addition, most frame grabbers also handle other signals for triggering, digital I/O, Encoder signals etc.
National Instruments frame grabbers go beyond image acquisition by offering advanced synchronization signals (RTSI Technology). This technology enables a frame grabber to synchronize image information to motion control and data acquisition cards in real-time. Total integration of complex automation systems is hereby easily achievable. |
