scaling camera shake pattern

hi!

I'd like to use a camera shake that rises the shaking strengh by time and also releases its strengh, let's say on event with a different time value. And i found those 3 camera shake scripts but i don't know how to scale it up, so it can start with a lower strengh by rising it from time to time stronger. how can i scale up and down a scripted shake pattern via code?
