According to foreign technology media AppleInsider reports, Apple recently obtained a technology patent, for the folding camera lens, you can make the back of the iPhone lens no longer raised.
The patent is titled “Folding Camera with Moving Optics Actuator,” and Apple has outlined a variety of ways in the patent that it plans to incorporate folding optics and lens movement in future iPhones.
Some of the patent design sketches are below, and in one example, Apple describes a system consisting of two prisms equipped with a multiple-element lens set between the two prisms.
The prisms steer light along an axis to the imaging sensor, while the lens set handles various optical functions. The lens set can remain in an internal carrier structure, which itself is attached to an external carrier structure. Both structures can be moved, thereby reducing the thickness of the lens.
Additionally, another case in the patent introduces a motorized actuator that can move the two carriers to achieve autofocus as required by the scene being photographed.
The second and third VCM actuators can be used to shift the internal carrier structure relative to the external carrier structure to improve optical image stability.
