请教Apple keynote中如何实现高清效果的webcam视频?

各位还记得每一次keynote demo中
对方的视频总是比steve面前的iSight画面清晰很多（右下角为isight）
不知道如何实现？
iChat接高清Camcorder 吗？需要什么软体吗？

The video quality of Steve’s iSight is not so good because the lighting on the Stage of MacWorld or WWDC is very limited.

Therefore the video quality decrease as a result of low light.

the Built-in iSight has a plastic lens, is fixed-focus, and uses a CMOS Active pixel sensor.
And The External iSight has Glass Lends, Auto Focus and uses a CCD Sensor.
