Pan and Scan means adjusting widescreen images so that they can fit into the standard ratio. It is an old television term!

If you mean Pan and Scan, it is only good for adjusting film format. It is the only capacity I coud find on the internet.

That is Pan and Scan. It it better than traditional fullscreen since it will pan and scan from side to side to show the entire widescreen frame, however it is not as good as widescreen since you lose whatever the pan is not showing.

A pan and scan is a method of adjusting widescreen movie images, such as 2.35:1 aspect ratio, so they can be shown within the proportions of 4:3 or 16:9, or a movie which is produced in this manner.

Historically theater screens are wider than television screens. To put the movie on TV, you either have to "Pan and Scan" or letterbox it. When the is letterboxed, you're actually seeing the entire picture as it was in theaters. "Pan and Scan" chops part of the picture off.
