Some of photos that I took look like this one. Look at the purple picture, it is supposed to be exactly the same as the one on the right-wall, window, etc. Nothing purple in it at all. This happens more often in open air / sunny weather but from time to time it happens randomly as well. I noticed that chances are higher if I take longer to focus/zoom, etc. At other times, photos look perfect. I tried to reset everything, adjust white colour settings, etc, but it does not seem to help much. I also tried different memory cards and still having the same problem.
My camera is Panasonic Lumix DMC-ZX1 and I'm shooting JPEG.
