Wouldn't an engineering design expert on CCD imaging be useful
here?

I believe there is a light level threshold that essentially
overloads the CCD and causes it to go black (and beyond a
certain level, damage to the CCD), but I've only seen that in
the earlier digital cameras.

There is also a process (circuitry and programming) that handles
variations in the light level and adjusts the contrast, which
can imagine would have limits in dealing with super bright
objects and simply wash everything else out.
