If you are using Unity pro then have a look at some of the image effects: http://docs.unity3d.com/Documentation/Components/comp-ImageEffects.html
One of them will probably do what you want.

If you are using the free version then I would suggest creating a semi-transparent plane in front of the camera with an animated texture on it which is enabled when you want the effect.
