In the camera preferences you can select the use of viewfinder grid, sounds, video stabilisation, and focus assist lamp. You can also define where the photos and videos are stored, and control the camera key function when the keys and screen are locked.
The digital video stabiliser compares consecutive frames and aligns them appropriately. In some cases, using video stabiliser might not give you the desired result. This can happen when you’re panning or otherwise moving or shaking the camera by purpose.
The focus assist lamp is used to help autofocus in the dark. If you don’t want the lamp to turn on when focusing, switch it off. However, then focusing might not work well in very dim conditions as autofocus needs some light to work.
To set the preferences, in the main menu, select Settings > Application settings > Camera.
