To turn on and off the PiP function see the PiP Mode section.
Press and hold the UP (5) button to change the magnification ratio in 
the PiPwindow.
The zoomed image is displayed in a dedicated window, while the image 
in the rest of the screen is displayed at base magnification (2x).
When the PiP is turned on you can control both the discrete and smooth 
digital zoom. In this case the zoom value changes only take place in the 
dedicated window.
When the PiP function is turned off, the screen will display at the 
magnification that was set in PiPmode.
