Sun Damage To Imagers?

I often hear that aiming a camera in the direction of the sun (directly east/west) will "burn out" the imager. However, I've only ever seen a couple of cameras with any damage from the sun, and they were likely aimed in that direction for years on end as they were quite old. Obviously, there are other problems which arise from having the sun in the image (reflections, lens flare, vertical lines and smearing, etc.), but actual damage seems rare.

So the question is: is this more security urban myth than fact? Have you ever seen sun damage to a camera's imager? If so, how long do you suspect it was happening?

Cross referencing this discussion: Can you kill a camera with a laser?

I have seen both sun and bright light damage to tube (Vidicon, Saticon, etc.) imagers but I agree with Ethan, it would probably take a very long exposure time to permanently damage solid state imagers.

Most of the time it is not the direct sunlight that damages the camera but is the reflection of it off the windows, shiny objects etc. For instance on the older CCDs, after a while there will be pink streaks or shapes of a certain window that will appear on the image similar to burn ins on the monitors.

The pink streaks are call bloom/smear which happens even on brand new CCD cameras. This is one advantage that CMOS has over CCD.
