Well, I would suggest there is a problem with your camera. I wouldn't hazard a guess at the potential cause, but it shouldn't be recording images like this, even for a '200 euros' camera. Though it would certainly be helpful if other e500 owners came forward with their verdicts.
To maybe help with a better diagnosis, has this always been the case from new ? Is it a recent development ?
Although thinking about it, it doesn't really matter which. I would be inclined to return it anyway. If you haven't owned it for too long, then I would return it to the store/supplier.
In the meantime, I hope someone else chips in with their opinion.
