MacCAM : ウィキペディア英語版
MacCAM

MacCAM (often written as MacCam, Mac-Cam or Mac Cam) is a system of slow-motion cameras developed by FastCAM Replay LLC and DEL Imaging Systems LLC used during Tennis matches to replay close or controversial line calls. The system is named after John McEnroe, who was infamous for contesting umpire calls. CBS was the first network to use the MacCam widely, as John McEnroe was one of their tennis analysts.
==History==
The MacCam was used at the 2004 U.S. Open to demonstrate several poor calls by chair umpires. In Serena Williams' controversial quarterfinal loss to Jennifer Capriati, several poor calls were contested by Williams. Television replays demonstrated that there were actually several crucial calls that were obviously erroneous. Though the calls themselves were not reversed, the chair umpire Mariana Alves was dismissed from the tournament. A major limitation of the MacCAM was that it could only evaluate the baseline—not sidelines or service line calls. It was ultimately supplanted by Hawk-Eye and similar technologies.
