On June 20, 2013, the US Patent & Trademark Office published two patent applications from Apple that reveal possible new improvements coming to future iDevice cameras. The first improvement involves providing iDevices with superior focus features while the second one relates to advanced video stabilization that Apple's engineer creatively calls the virtual tripod. Apple began working on video stabilization back in June 2011. A secondary patent months later once again illustrated that Apple's camera team were very focused on bringing video stabilization to iDevice cameras. Apple first introduced basic video stabilization on the iPhone in October of that year. Today's patent application both illustrates and confirms that Apple's push to achieve superior video stabilization results is an ongoing project.
