When changing FPS from 15 to 24 video is much darker

Open vovkab opened this issue 8 years ago • 4 comments

Hello

I've been trying the demo app and when I change to 24fps video is much darker now. Is there anything I should change to make it lighter, enable some auto mode?

Thank you.

Which device did you test? It may be the device camera limit.

I'm testing it on Google Pixel. What I think is happening is when we change fps it doesn't adjust ISO and shutter speed, so video is much darker.

I used ProShot app to manually adjust iso and shutter speed while using 24/30fps, and I was able to make video brighter. But then if I change it manually it doesn't auto adjust if light around is changed.

So I think some extra configuration is missing in KSY lib.

Did your Pixel running Android O preview? It should be the camera device driver or HAL issue.
System Camera API should be guaranteed to adjust ISO automatically if needed.

If you find the same problem while running stable Android M, please let us know.
