Single point. The sensor averages the temperature of everything in a 10° FOV, which should be suitable to get an average pan temperature.
I think you could do something more clever with an IR camera like you suggest, by identifying the edge the pan, and giving more info like the temp gradient, perhaps displayed as 2 temps. Ie, "edge temp", and "center temp".
