According to the US technology blog site Appleinsider, Apple's patent application was announced on Thursday. The document shows that Apple intends to introduce 3D imaging technology into its mobile devices to develop a patented system similar in functionality to the Microsoft Kinect motion sensor.
Apple's patent application is called "Imaging Range Finding Device and Method." The idea behind the patent is to place a row of light emitters and photodetectors behind the optical lens, which is responsible for directing light to the target object. According to the light emitted and reflected by the device, and the light emitted by the object itself, the volume and corresponding position of the object can be determined. If one or more movable lenses are added, the accuracy of the system will be improved and can be used in harsh environments such as smokey rooms or hazy weather.
Apple's ranging patent has many uses:
- Scan and measure internal space; for 3D object scanning and pattern matching;
- Provide navigational assistance to visually impaired users, such as detecting landmarks, stairs and similar objects;
- Automatic foreground/background segmentation, real-time motion capture and avatar generation;
- Picture editing;
- Night vision function to view the surrounding environment without being affected by bad weather;
- Computational imaging, such as adjusting focus and lighting conditions after acquiring images and videos;
- auto focus and flash;
- two-way communication;
- File transfer to locate people or objects in the room;
- Capture remote sounds.
It can be seen that if the patent application is approved and put into practical use, it can undoubtedly be widely used in various services of the medical and health industry.
