I want to create interrupts

    % Video preferences
    %vid = videoinput('winvideo', 1); % Next line is alternative to this one if you know the format
    vid = videoinput('winvideo', 1, 'MJPG_1280x720');
%     vid.FramesPerTrigger = Inf;
        vid.TriggerRepeat = Inf;
    set(vid, 'ReturnedColorSpace', 'RGB') ;
    set(vid,'FrameGrabInterval', 3);
    % Preview
        figure
    % Get frames
    start(vid);
    wait(vid,inf);
%     frames = getdata(vid);
    vid.FramesAvailable
    % Save frames
    while(vid.FramesAvailable >= 2)
    data = getdata(vid,2); 
    diff_im = imabsdiff(data(:,:,:,1),data(:,:,:,2));
    diff_im
    imshow(diff_im);
    drawnow     % update figure window
end
%     folder = strcat(foldername, '/');
%     for k = 1 : framenumber
%         mov(k).cdata = frames(:,:,:,k);
%         imagename=strcat(int2str(k), '.jpeg');
%         path = strcat(folder, imagename);
%         imwrite(mov(k).cdata, path);
%     end   
    stop(vid);
    delete(vid);
    clear vid;

The requirement is that I do not have interrupt support for capture time. Want to help Want to clear When using images that capture frames per frame

Question is not clear.....can you elaborate? What you want to do?

The program wants to record a room image in real time, save a frame per frame. Time will take the previous frame to remove it to the next frame and continue processing in the program. But still not able to clear data when the result is finished.And get the data processing is done and delete the data all the time.
