Hello. This is a general question about image aquisition using the imaq tool box. The Matlab documentation uses quite confusing terms such as logging and running. What do these physically mean in simple terms?

I want to enable fast image capture and use a single trigger to e.g. set off the camera to collect 20 images:
vid=getVidObj(app);
n=20; % Snap n Images when triggered
vid.FramesPerTrigger=n;

% Start Camera running (not transferring images yet)
start(vid);
trigger(vid); % This inititates te Camera to collect images
tic;
pause(0.01);
[frame,time]=getdata(vid,n); %Just get n fram
tframes=toc;

My questions are:
1: Before getdata is invoked, and the camera has been triggered, are the images on the camera in some kind of memory or do they stream straight to the RAM
2: When getdata is performed, it returns n=20 frames (images). Where are these actual images, are they in RAM on the PC.
The logging and running terminology doesn’t inform of where the actual image data is.

Thanks
