Yole Hypotheses on iPhone 8 3D Technology

Yole Developpement analyst Pierre Cambou posts his guesses on what technology might be used in Apple iPhone 8 3D camera:

"Until earlier this year everyone thought 3D cameras would appear on the rear of Apple’s new iPhones, as is the case in the Lenovo Phab 2 Pro, in order to develop Augmented Reality applications. This changed radically when Ming Chi Kuo, an analyst from KGI Securities, confirmed in April 2017 that there would be a front 3D camera... Most analysts speculate that this camera would exploit “structured light”, because of Primesense’s involvement. However, Yole maintains its original idea of a Time of Flight (ToF) camera on the front due to the nature of the application, which is to be a new revolutionary user interface."


  1. I do know that it's using a laser illuminator.

  2. claims are free. no one would come collect if they got it wrong (and they did).

  3. I (think) I agree with Roi, the claim that a TOF will be used for (my added word) accurate Facial Recognition is ahead of it's time.

    Infineon claims their large and medium priced solution is accurate to a mm, while STM's tiny and less expensive (which Apple has used previously) is accurate to a cm (neither as good for Facial Recognition as other solutions, but better for CPU).


    Yole's recent Report: - see page 8, amongst others.

    Cheap and tiny TOF is low resolution in XY&Z, Structured Light or two Cameras are better, but computationally expensive; using TOF to lower the computational expense of ultimately using 2 Cameras is possible, but not very TOF (pun intended, and essentially a 3 Camera solution).

  4. ToF is not that computationally easy either. You need to blast out several phases and frequencies to avoid ToF unique artifacts of anti-aliasing and multipath, and those need processing on the 'host' to derive the depth map. And a set of gates can easily solve the SL computing load, as Primesense amply demonstrated. ToF by nature can be noisy in the Z dimension, do note, relative to SL or Stereo.
