IMAQdx Image Capture w/ Onion Skinning

[HunterSeeker]

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.

Help Needed

This program current works pretty well, but the Onion Skinning subVI is not very efficient. The RGB conversion functions take a lot of processor power to comlete, so it slows down the live aquisition too much. If anyone has any ideas on how to optimaize please share.
