I have merged your questions that are all about the same issue.
You will need to look into the API here: http://docs.phonegap.com/en/2.9.0/cordova_camera_camera.md.html#Camera
Setting your options as per the documentation should do it:
saveToPhotoAlbum: Save the image to the photo album on the device after capture. (Boolean)
Camera.DestinationType = {
DATA_URL : 0, // Return image as base64-encoded string
FILE_URI : 1, // Return image file URI
NATIVE_URI : 2 // Return image native URI (e.g. assets-library:// on iOS or content:// on Android)
};
If it does not you will need to search for how to move a video file into the photo library from the above location.
