This is my program that I can take a screenshot only once.
i want to take screenshot continuously in video by pressing key.
Can I do this by adding an index?
thanks before.
a = imaqhwinfo;
vid = videoinput('winvideo',1);
set(vid, 'FramesPerTrigger', Inf);
set(vid, 'ReturnedColorspace', 'rgb')
vid.FrameGrabInterval = 5;
start(vid)
while(vid.FramesAcquired<=200)
Key=get(gcf,'CurrentKey');
if Key =='s'
img1 = getsnapshot(vid);
break;
end
