A caveat of frame-grabbing, to me at least, is that this implies using video, and inexpensive video really ..... . For my application, the only additional cost was $30.00 for an eBay digital camera that has much higher resolution with great exposure and color control. To me, video is only good for full motion applications and requires at least an order of magnitude more money to get decent results. I would love to see an open source HD video project. The Elphel http://www.elphel.com/index_en.html seems to try to be open and has very good image quality. ------------ Kirk http://www.wallacecompany.com/machine_shop/ ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
