Overview
This VI is designed to connect to a USB webcam using IMAQdx and allow the user to capture individual frames and play them back at a given speed to allow them to create simple stop motion animations. The "Onion Skinning" feature allows you to show a transparent previous frame on top of the current frame, in order to align images for sequential frames.
Steps to Implement or Execute Code
- Connect a USB webcam
- Run the VI
