Image Acquisition - preview is fast, snapshot is slow?

Asked by Brian

Why is the snapping of frames so slow?

It seems that preview can be used with a callback to do real-time processing of images. However, snapping a frame, then calculating and displaying the result is very slow.

What is the best way to approach (quasi) real-time video processing?
