QUANTITATIVE-EVALUATION OF LOW-COST FRAME-GRABBER BOARDS FOR PERSONALCOMPUTERS

Nine moderately priced frame-grabber boards for both Macintosh (Apple Computers, Cupertino, CA) and IBM-compatible computers were evaluated using a Society of Motion Pictures and Television Engineers (SMPTE) pa ttern and a video signal generator for dynamic range, gray-scale repro ducibility. and spatial integrity of the captured image. The degradati on of the video information ranged from minor to severe. Some boards a re of reasonable quality for applications in diagnostic imaging and ed ucation. However, price and quality are not necessarily directly relat ed. (C) 1995 by W.B. Saunders Company
