Horizontal Lines on Webcam Feed because of LED Flickering on Openframeworks + OpenCV

I am having horizontal lines in my webcam feed in Openframeworks and I am using a Playstation Eye cam with ofxPS3EyeGrabber to achieve this. I have also tried opencvexample sketch but it looks like the same.

For the context, I am trying to create a real-time hand drawing tracker by using a webcam , lighttable and some transparencies. So the idea is to digitalize the drawn sketch on a transparent acrylic sheet by using computer (similar to an overhead projector). The setup is similar to “Where do you call home?” by Peter Thompson (2008) https://vimeo.com/122126723.

I have also checked this thread but I can't solve my problem with the suggested solutions.

Does anyone have an idea how I can tackle this problem?

You can use some white LEDs or IR light to do the illumination. But you should strobe them when the webcam captures the frame.

There was a good example on how to do VSync in the EyeWriter Instructable. I hope this is what you're looking for.
