The finalize method of class Object performs no special action; it simply returns normally. If for both axes a common focal length is used with a given aspect ratio usually 1 , then and in the upper formula we will have a single focal length. The equations used depend on the chosen calibrating objects. In particular, Licensee must ensure that a reasonably distinctive and conspicuous visual indication that a Recording is taking place is displayed to the user as part of the Application.

If you opt for the last one, you will need to create a configuration file where you enumerate the images to use. In a smartphone, the camera module is quite tiny, owing to the fact that the phone itself has to be slim.
