It will be worth the wait for the separate release dates of iPhone 6 and iPhone 5S as Apple inches closer into delivering powerful camera features for the twin iOS 7 devices, to be protected by a biometrics-enhanced security tool.

The latest patent applications from the tech giants revealed three killer features that likely will be showcased on new iPhone iterations over the next three quarters, new reports said.

The first two technologies involve advance iOS camera features that according to Patently Apple are deployable to mobile device snappers and webcams used in Mac notebooks and desktops.

In the first invention, Apple engineers aim to achieve superior auto-focus capability for iOS-designed camera through the use of motion sensor and gravity vector, arming the iPhone shooter with accurate calculation of a subject's orientation.

Upcoming devices from the company will employ "a lens position measurement system that could work with camera-enabled electronic devices including digital still cameras, camcorders, camera-enabled phones, webcams and security cameras," the Patently Apple report said.

Along with this new system, Apple will also introduce the use of a digital tripod, a camera functionality that eliminates unwanted motions during video capturing procedures.

Dubbed by Apple as a 'virtual tripod', the digital camera stabilisation system will "distinguish between intended and unintended motion, so that only unintended motion is eliminated," the same report said.

Once implemented, Apple foresees wide use of the new camera feature and will likely see integration with the FaceTime app that is deployed both in the iOS and OS X environments.

Rounding up the exciting new Apple offerings is the much talked about fingerprint sensor, which like the above-mentioned camera features are designed to enhance Apple devices across the board.

The possibility of iOS and OS gadgets getting more solid security features came closer to reality on the strength of Apple's new patent application titled 'Integrally moulded die and bezel structure for fingerprint sensors and the like'.

To bring forth this new protection technology, Apple will design "a unitary encapsulation structure that protects a delicate biometric array, while still allowing for a portion of the sensor and bezel to be exposed or thinly coated with a protective seal," Apple Insider said on its report.

The same mechanism with a sensor die will be embedded into the bezel of a device, an iPhone for example, to provide secure authentication prior to performing numerous smartphone functions.

"By encasing both the bezel and the sensor die in the encapsulation structure, those elements may be brought closer together than heretofore possible. In addition, the encapsulation structure physically protects the bezel and sensor die," Apple's patent filing was reported by Apple Insider as saying.

Among the supposed iPhone capabilities that came out this year, these three features have the highest chance of actually making it to the final iPhone 5S and iPhone 6 builds, supported by Apple's existing technologies.

Apple will likely the iPhone 5S September this year while the allegedly phablet-size iPhone 6 is reportedly slated for a release date anytime between January and March on 2014.
