How to reduce Image Acquisition time

Hello, elapsedTime for the following code equals 1.0592 seconds.

imaqreset
vid = videoinput('pixelinkimaq');
src=getselectedsource(vid);
set(vid,'ROI',[0 0 64 64])
set(src,'FrameRate',150)
set(src,'Exposure',0.002)
set(vid,'FramesPerTrigger',150);

triggerconfig(vid, 'manual');
start(vid);
tic
trigger(vid);
wait(vid,Inf);
frames = getdata(vid, get(vid,'FramesAvailable'));
elapsedTime = toc

I really really need it to be less than 1 second. Any Ideas how running time can be reduced?

THANKS

You asked for a FrameRate of 150 frames per second, and you asked for 150 FramesPerTrigger, so you are asking for 150 Frames Per Trigger / 150 Frames Per Second = exactly 1 second per Trigger. You cannot reduce the acquisition time for 1 second's worth of frames to below 1 second.

Thank you Walter. Of course you're right. I've meant is it possible to reduce the run time somehow? Make it close to 1 sec (RealTime) as much as possible.

How long does it take now?

I don't know that it's any different than the 1.0592 seconds he originally said, unless he decided to record fewer frames, like the 140 I suggested.

1 second takes me ~1.5 seconds to processed and display. Trying to solve this with buffer and parallel computing...

What if you try

set(src,'FrameRate', 160)

or

set(vid,'FramesPerTrigger',140);

How long a time do those give you?

[Image Analyst]

Mark, did you try my answer yet? You might just have to do trial and error to "home in" on the setting that produces a length as close to 1 second as possible.

I can't , I need to work with fps 150.
