CVI stands for Concept VI, the name of the library when it was owned by Graftek.
The names of the VIs have since been changed and other capabilities have been
added.
All of the VIs operate on an image reference, a cluster that contains a string
and a number. At
any point, you can get the raw data from the image and display
it into an intensity graph, a picture control, or an image display
window. There
are tradeoffs to each of these. The intensity graph is built-in, but it isn't
the fastest display, its limited to 256 colors simultaneously, and it
allows for
cursors, but not regions of interest. The picture control is similar,
but allows
for true color images, no cursors, but any annotations and regions of interest
with a little programming. The image windows that are a part of Concept
VI or
later versions from NI are the fastest, and offer the most image centric feaures,
but they are in external windows (usually not a problem).
You can probably find more info on more recent versions of the Vision
and Imaq VIs
on NI's web site
