It's said that the tech giant's 2019 version of its phone will make use of a new sensor to give the quality a boost.

According to analyst Ming-Chi Kuo, the sensor will illuminate the user's face in a beter way "to lower the impacts from visible lights of environment in order to improve the Face ID user experience".

As reported by MacRumors, he explained: "We believe that Apple will raise the output power of the flood illuminator VCSEL to lower the impacts from invisible lights of environment in order to improve the Face ID user experience.

"The higher power VCSEL with higher ASP needs increased requirements of design and production, increased materials for array design, and longer testing times. Therefore, the VCSEL supply chain can add higher value."

Meanwhile, it's also been suggested that Apple could look into introducing a Time of Flight 3D camera into either its 2019 or 2020 iPads.

This sensor would measure the time in which a dot of light travels between the camera and its subject, in order to make 3D images.

Kuo noted that this feature could be used either to improve image quality, or even for augmented reality experiences.
