After 4 years of bulletproof service, my Canon digital camera has gone
goofy.

On July 21st it shot a few "purple shots":

On July 26th, it was normal again.

Then on Aug 29th, it went psychedelic and never came back:

The day it happened, I took the camera out of a nice air-conditioned house
and into the usual 95°Texas summer day so I'm wondering if condensation
hosed the CCD or something. I find the fact that it "healed itself" once
encouraging, but after several days there's no improvement.

Given that it's only a $200 camera, I'm guessing it wouldn't be worth it to
send it to Canon's service facility. If it's really hosed, I figure I might
as well open it up and see if there's anything obviously wrong inside.

Any ideas here as to what it might be?
