you can run it up in that range but unless its a high quality professional grade you see very little benefit over 640x480

if it's an NTSC cam for example it's interlaced anyways, so every capture you get has only 260 lines (then it's called a 'field a' or 'field b', and two of those together make a frame) - unless your driver has already de-interlaced the picture and then you'll get the 520 lines

usually though the first few lines are screwed up due to the sync process so you crop till you end up with 480 good ones
