Apple website states that it's capable of FullHD that's 1920x1080. Interesting fact that when I capture a stream like this:
const s = await navigator.mediaDevices.getUserMedia({ video: { width: 1080, height: 1920 } });
it'll have larger FOV than when it's landscape-oriented.
Another thing that's available in Chromium-like browsers is getPhoto() API, and for it (https://simpl.info/imagecapture/ or https://googlechrome.github.io/samples/image-capture/grab-frame-take-photo.html ) it shows image of 1552x1552 that's a bit narrower for FOV than FHD frame, but much higher and has bigger vertical FOV.
I can conclude physical image sensor is at least 1920x1552 px. Does anyone know exact dimensions or has a link to a datasheet for the camera module that's used in those Macs?
I tried to find some data on Internet but haven't succeeded so far.
