IF, and it is a big IF. If you measure your system very well -- knew the driving frequency and mass distribution, you could indeed identify where to add or subtract mass so that the camera happens to be at a node with little or no vibration.
This link shows examples of a simple system. They don't change the mass, but change the frequency to cause standing waves where some portions of the spring are in a quiet place while other portions of the spring are bouncing all about.
Again, I'd try to get rid of the source. Strong vibration will do more than cause bad images. Before long, you'll see that the bolts are loose, welds break, cables loosen or break, not to mention shaking the chips off of the camera's circuit board.
