vid = videoinput('winvideo', 1, 'YUY2_640x480');
src = getselectedsource(vid);
vid.ReturnedColorspace = 'rgb';
count=0
for i=1:5
preview(vid);
framesPerTrigger = 1;
set(vid, 'FramesPerTrigger', framesPerTrigger)
get(src)
fps = 30;
set(src, 'FrameRate', num2str(fps))
acqPeriod = 5;
frameDelay = fps * acqPeriod
set(vid, 'TriggerFrameDelay', frameDelay)
acqDuration = (acqPeriod) + 3
vid.Timeout = acqDuration;
start(vid)
wait(vid,acqDuration)
g=getsnapshot(vid);
figure, imshow(g)
saveas(gcf,'A.tif')% I want to save the g as *.tif sequencly exp. A1,A2,A3....

Have you looked at the links that I gave you, that's explaine din quite some detail there.
Something as simple as this should work;
g = getsnapshot(vid);
figure, imshow(g)
fname = ['A' str2num(i) '.tif'];
saveas(gcf,fname);
HTH,
Arnaud
