Can someone please tell me what AI Servo stands for? I know what it does on the Canon 20D, but I would like to know what the "AI" abbreviation means.

Thanks.

Ripped from a website after a very quick google search:

--------

AI Servo AF is an autofocusing system designed exclusively for Canon EOS cameras. It uses a form of Artificial Intelligence (AI) to determine the speed and direction of moving subjects, then focuses the camera lens to a predicted position (Focus Prediction Function) in order to increase the probability of obtaining a sharp photograph.

"AI" artificial intelligence ( thats a guess ) ..
servo is a motor with precise control over position

In practical terms it means the camera continually focuses, meaning you can track a moving object and keep it in focus. You do this by half-pressing the shutter button.
