Strange camera behavior on airplane. (LED overhead lights)

When flying earlier today I noticed something strange with the Pixel 2 XL camera. This happened with both video and photo. Also on both the front and rear camera. When shooting the picture will pick up major banding. Then with video the bands dance. This could be an issue in other LED lit environments also I just not been able to test. The camera appears to work great in normal conditions.


Here is a link to the video: https://youtu.be/nCLayJZ2Eyc


Here is a link to the photos (turn motion on): https://photos.app.goo.gl/DgIYd1pxbMwBt0Z62


Anyone seeing this behavior? Also you'll notice the poor audio on the video. That's another issue.

Here are a few more examples. Looks like any LED will be a problem for the Pixel 2 XL camera. https://photos.app.goo.gl/gJqyeZ20Ms5GwC773

Hi Chazzdjr,

Thanks for posting on the Pixel User Community. 

I understand that you are facing issues with the camera of your Pixel. Please give the below steps a try and check if that makes a difference:
  • Try clearing the cache of the camera app. 
    1. Open your device's Settings app Settings app.
    2. Tap Apps & notifications.
    3. Tap See all apps and then the app and then Storage. (If you don't see "See all apps," tap App info.)
    4. Tap Clear data or Clear cache. (If you don't see "Clear data," tap Manage space.)

Let me know how it goes.

Best, Matt

This is a Pixel 2 camera issue, Matt. Those steps are not going to help. Another user with a similar report: https://plus.google.com/+EricBraun52807/posts/YrKQxgxCMyu.

Let me escalate this to make sure the team is aware.

LED and fluorescent lights do not emit a steady light but flicker at the frequency of the AC power supply. In the US that would be 50Hz. The banding you see in images is caused by this. In order to prevent banding you need to set the shutter speed (electronic shutter in the case of phones) to multiples of the light source frequency, so in the case of the US it would be 1/50s, 1/100s, 1/150s, etc. Any other shutter speed will capture the banding effect. Sadly there's no shutter speed control on the native camera app for Pixel phones. Here's a short video that explains the effect: https://www.youtube.com/watch?v=srQlxkdpLAs

The standard AC frequency in the US is 60Hz.  But on aircraft it's usually 400Hz.  https://en.wikipedia.org/wiki/Utility_frequency#400_Hz

The camera should automatically detect this issue through machine learning and adjust accordingly... This is a pretty big issue for "the greatest smartphone camera".

I'm having the exact same issue under LED lighting in various spots at work

How do you explain the samples in this video then? https://plus.google.com/+EricBraun52807/posts/YrKQxgxCMyu. The Nokia 6 has nothing like that, and the samples from the Pixel 2 XL look wildly different from the flicker you'd expect (shown in the video above).

I got my second replacement device, and, as expected, it has the same issue.
