请教 video resolution 的2个问题:

来源: rhealthy 于 2006-04-24 08:55:46 [] [旧帖] [给我悄悄话] 阅读数 : (453 bytes)

A - CCD with 340K (effective) pixels
B - 500 lines of horizontal resolution
C - MPEG Movie: 640x480 VX Fine w/audio at 30fps

A and B are for handycam, what's the difference.
C is for digital camera's video function, how to compare such kind of resolution with the upper two specification?

I am thinking to buy a digital camera with video function so to save money on a videocamera.

Any idea will be greatly appreciated!
