Hi there,
You're image is a bit hard to see, but it looks like a problem I experienced a few months back. The cause seemed to be asynchronisation of the shutter speed with the mains frequency of the fluorescent lighing in the room I was working in. I solved this by adjusting the shutter speed so that it matched the frequency of the lights (2*50 Hz = 100 Hz where I am). In Raspicam language, that's a value of 3.03 for CV_CAP_PROP_EXPOSURE. Hence, my code was something like:
#define IMG_SHUTTER_SPEED 3.03
...
raspicam::RaspiCam_Cv Camera;
Camera.set ( CV_CAP_PROP_EXPOSURE, IMG_SHUTTER_SPEED);
...
Hope you find that helpful!

Thanks, I will test this!
