bna08 Posted December 21, 2022 Report Share Posted December 21, 2022 I have an IMAQ image in my application and when I try to write new pixel data to it and update it more frequently than approx. each 40ms, the image in the display is torn. If I am saving each image to the disk, it looks good. It's just slightly broken when an object is moving fast in the field of view. What I am doing is: Write pixel data (via pointer from IMAQ GetImagePixelPtr.vi) to the IMAQ image every 20-30ms. Immediately push (write) the IMAQ image with new pixel data to IMAQ Image control. Is there perhaps some kind of "native" refresh rate of 25fps (40ms) in the IMAQ image control that would interfere with me writing and displaying new image more frequently? Quote Link to comment
