Der Schaden war sofort sichtbar und hinterließ eine zwischen Rot, Rosa und Violett changierende Farbkonstellation. Betroffen war nur das Teleobjektiv, da das Bild nach dem Herauszoomen auf ein anderes Objektiv wieder normal angezeigt wurde.

My German skills are moderate, but does that mean it's only when pointing at the LIDAR, and everything went back to normal when pointed somewhere else? I also don't get how zooming is a factor?

If that's the case, I don't really see a problem? And I find it weird to claim the camera is damaged?

Weird article...

Edit: The zooming is probably about switching camera, but just calling it zooming is misleading, because not all phones have separate cameras for that.

No, the LIDAR is an infrared laser. Invisible and harmless to the human eye, but a phone's camera can pick it up. And due to the intensity, if going too close, it'll burn out the pixels of the camera sensor leaving permanent damage.

Here's a great demonstration: https://x.com/niccruzpatane/status/1924485047580586294

Thanks, that's a very good example. 👍
What was confusing about the article, was the stupid part about the problem going away when zooming out? Which in fact is probably switching to another camera.

[–] mbirth@lemmy.ml 2 points 2 weeks ago

It was exactly this and people were furiously pointing it out in the comments.

No. It is written badly. They say after zooming out it was good.

I can only imagine that this phone had several camera sensors, one of them got damaged, and with zooming out it switched to another one.

[–] Buffalox@lemmy.world 1 points 2 weeks ago

Yes, I've come to that conclusion too.

[–] PostnataleAbtreibung@lemmy.world 3 points 2 weeks ago (1 children)

I couldnt read it because paywall, but from what i understand is the teleobjetive got damaged, it seems there are phones with more than one camera?

And you need to be really close.

I just opened in privacy mode, and it worked for me.
I agree, I just said this to my wife, showing if I use zoom it's a different camera, so if I zoom out again yes of course the problem goes away, it's a frigging different camera! What's the point of stating that? But I don't have a "teleobjective" on my phone, as much as I have a Telephoto camera, so weird wording in the article IMO.

Phone cameras have infrared filters because the infrared causes images with too much red and generally weird colors. I once removed the IR filter on a webcam to try to improve light sensibility, and the colors became outright awful.
But maybe the LIDAR infrared needs to be a tad lower to be filtered more efficiently? Because it seems to me you could sue the LIDAR company for damaging you phone if it breaks the camera to film you new car.

The switching is noted in the text. However, the wording is a little off since they refer to the lenses and not the camera sensors behind.

[–] Buffalox@lemmy.world 2 points 1 week ago (1 children)

auf ein anderes Objektiv

But Objektiv is just the lens? the real thing that is switched is the camera!
Very weird way to express it.

[–] n3cr0@lemmy.world 2 points 1 week ago (1 children)

Exactly. That's what I mean by their wording being off a little.

Oh sorry, my mind must have been a bit foggy when I read that.
