You can't delete the camera roll it is the default location for photos to go to when you take a picture or video. You might try to sync using iTunes on a computer and see if you can leave photos unchecked.

Syncing through iTunes won't help because that is not where synced photos are stored on iOS devices - they are in a folder that you name in iTunes (mine is iPad Photos).
The only way to clear the photos from the Camera Roll is to tap SELECT at the top of the screen, then tap all the photos so there is a blue checkmark on each of them and then tap the TRASHCAN at the bottom. You can select all the photos, but must do it individually.
