Image Acquisition Toolbox - How can i get that Live-FPS status in my own code?

Hello Guys,

i am working with the Image Acquisition Toolbox. I build my own GUI, where u can see the live preview of the camera and change some of the camera-parameters like shutter, exposure etc. It is important to me to see the FPS wich can be gained with the choosen shutter. I know, that the Image Acquisition Tool itself has that live FPS-display. Is there any (easy) way to generate that live FPS-display?

Thanks and best regards
