I looked fussy to others

I used my ipad for my weekly recurrent meeting.  But today,, when I signed into the meeting. I looked blurry, not the background, the whole screen, in fact, it looks like there is a lot of light going into the room type of exposure though it is not in reality.  I logged off,  check my camera by taking a video and it was fine.  I used my iphone and desktop to log on and they were fine.  But when I used my ipad, it is not.  I tried to start a meeting and same thing.  I signed off, I powered off, nothing change.  Help
