[Kernel-packages] [Bug 1667180] [NEW] Image flickering with 50 Hz lighting

2017-02-28 Thread Launchpad Bug Tracker 
You have been subscribed to a public bug:

The webcam in Linux has a system that compensates the blinking of
lighting under alternate current. Which cannot be perceived by the human
eye, but when recorded it flickers the image.

The problem is that depending on the country you are the current blinks
either at 50 or 60 Hz. Linux has its frequency set to 60 Hz by default,
but using that one in a 50 Hz country renders the system noneffective,
getting likely the same flickering as there was no compensatory system
in place.

You can see the effect in the following video:

The computer needs to detect that you are in a 50 Hz country, and change
the setting accordingly.
