Seeing this thread is tagged linux, I'm guessing heavyd's answer does not suit you, albeit being complete.
I'm not a VLC user myself but I'm guessing once VLC is displaying the video, there should be a menu with a "Video properties" item or something similar.
On the other hand, you could try to use the camera using mplayer and see what it outputs.
Open up a console, and type the following :
By now, a new window should have opened along with plenty of text being printed inside the console.
It should start by saying which version it is, followed a few lines after by "Playing tv:///"
The line you're looking for is
Current format: [format here]
Selected video codec: [blah] vfm: raw (RAW *interesting_info_here*)
MPlayer can be compiled with various options and the output will differ, which is the reason why I explicited two possible locations where you can find the information you're seeking.
After a bit of googling, this link suggests your camera can output YUYV or MJPEG.
