Screenshot on Yocto

[damadamn]

I would like to do a screenshot of the yocto terminal, and I don't know if it is possible?
My Aero RTF is directly plugged into a screen and have got a keyboard, and I can access to it with ssh command line, but this isn't possible to do the screenshot on the desktop of m computer because i'm working on the Realsense R200 of the Aero.The computer teminal can't display Realsense video with gst-streamer, so that's why I would like to know if there a way to do it on the Aero.

PS : this screenshot is for my internship report, so I wouldn't take a photo of the screen (you know, the quality of the picture would be ... pretty horrible, depending of the screen)
