Frame Grabbers

Interfacing Adaptors

What is a frame grabbers?

A frame grabber is the interfacing card between the camera and the PC. It is one of the key elements in an image processing system. It is use to acquire video information and to transfer that information to the succeeding stages of the system.

Frame grabbers convert video images from cameras into digital format and transfer these digital images to PCs, which use the converted data to make decisions about the object(s) being inspected. Though performing these functions quickly and reliably are critically important to the success of a machine vision inspection, frame grabber is much more than mere data converters and transfer conduits. Frame grabber offers a range of capabilities that can compensate for poor lighting, optics and ways that camera sensors present information to the frame grabber, increasing the quality of the images acquired and, ultimately, helping the machine vision system perform more reliable inspections.
