There are lots of frame grabbers less expensive than PCVision. There are frame grabbers made for grabbing and displaying images, frame grabbers made to process images, and frame grabbers made for multimedia applications. PCVision was made specifically to process images for high performance machine vision applications, and it's price is extremely competitive in this class. They have PCI bus interfaces, but the memory is not optimized for transferring data to the host. Instead, it's made for displaying the data that was captured.
Users generally process the image for a Web site or a photo album.
Typical markets are home or consumer applications. For example, PCVision not only interfaces to RS170 data, but it also can interface to any sensor up to 1K x 1K, and up to 20MHz. Also, other frame grabbers in this class only sync via a PLL whereas PCVision can drive the camera. This particular feature is an important difference. Read our Privacy Policy .
