Downsampling images in Labview

Hello

I am collecting data from an Apogee U10 camera that is not directshow compatible. I can get the images and display them on an intensity graph but the loop is slow. The images are large (2060x2060) so i could stand to loose some of that resolution so that I can speed up my application. Any suggestions on how to downsample the array matrices that the camera methods are spitting out would be helpful. I have attached the vi below

Thanks

P

after getting the image you can resample it. In vision assistant go to images-->image geometry-->resampling

Are you sure it's the displaying of the data that is slow and not the acquisition of the data?  If it is, then use a queue to separate the display from the acquisition.  See attached image.  It uses a lossy queue to pass the data to the display loop.
