All depends on the place where you are seeing them. I saw them in France twice last November - in Lyon they did a search, but didn't care about the point & shoot camera. (Pretty much the rule - no cameras with removable lenses.) In Toulon, they didn't look at all.
Unless they are being particularly crazy about cameras, I think you should be fine for getting one in. Hiding it in your boxers works - except if they use a metal detector!
The real problem is once you're inside, it just takes that one security guard in front of you that doesn't know or wasn't paying attention that day that they were told the Scorps don't mind cameras.
Get a phone with a good camera. If you are up front they turn out pretty good.
Have a great time in Lille!
