Iphone 5s weird colorful thin vertical lines on back camera?

Hello,

Whenever I try to take a picture with my backside camera, my camera has these weird glitchy effect. It's not the screen because when I send pictures you can still see the lines. My front facing camera still works, it's just the back camera that gets all weird. I didn't drop my phone too, I was on a airplane and I wanted to quick take a picture of the view from my window but it looked like this. I don't know what's wrong like is this a small thing that I can fix on my own or am I going have to take it to a shop and get repairs done? Any advice would be helpful .

Thank you!
