/**
 * Denotes that the annotated method uses the experimental {@link ImageProxy#getImage()} method.
 *
 * <p> The getImage() method makes the assumptions that each {@link ImageProxy} is the sole owner
 * of the underlying {@link android.media.Image} which might not be the case. In the case where
 * the Image is shared by multiple ImageProxy, if the Image is closed then it will invalidate
 * multiple ImageProxy without a way to clearly indicate this has occurred.
 *
 * <p> When using this method it would be recommended to not close the Image via
 * {@link Image#close()}. Instead when the Image needs to be closed, {@link ImageProxy#close()}
 * should be called on the ImageProxy from which the Image was retrieved.
