Cameras aimed at the consumer mass market produce comic-like, exaggerated colours because the target group likes colourful pictures and is easily awed enough by saturated colours to overlook other flaws. Cameras aimed at more serious amateurs have to cater to somewhat more refined and critical tastes.
The FZ-50 pictures you posted above are a good example. You may find them nice and colourful, but to me they look awful (in particular the skin tones look very waxy/plasticky). To each his/her own.
Edit: You also find similar patterns in the film market. Most mass-market colour films emphasize colour saturation and contrast, but there are more neutral/muted "professional" versions available e.g. for portraits.
After the camera took the shot, it will sort of do some basic editing for you such as adjusting colour saturations and sharpening of picture... It is meant to be good to use straight after shooting with minimium post processing...
After the camera took the shot, it doesn't do everything for you. You have to do post processing such as adjusting your constrast, colour saturations etc by yourself.
Unlike pictures produced from consumer/prosumers, you get more control over the picture for your post processing... It is like comparing RAW with Jpeg (on the same camera)...
