I've made a mosaic dataset of some thermal imagery. There are three overlapping images, seen here:
As you can see, there is a discontinuity (jagged edge) between the two images on the right, and a slight offset in the southern fenceline. I want to tackle this using the Blend function in ArcMap 10 to "average out" these small differences and create a seamless mosaic.
The online help tells me there should be a Blend Width option to control the area over which the rasters are blended… However, this is all I see:
How do I do this?
I've looked in all the other tabs/online and can't find anywhere to define the blend with. I feel like I must be missing something obvious… I am using ArcMap 10.0 with an ArcInfo license on Windows 7.

Based on the help you linked to, it doesn't seem like that is setting that can be changed. I know it's semantics, but you'll notice that it says:
For the other options, it says "Allows you to define" or "You choose".
However, if seamlines are present, it would appear that you can define the blend width:
This ESRI article would also support that the blend width is dynamic, and changes based on your zoom level.
Lastly, the Build Seamlines tool has a parameter under the Advanced options to set the blend width.
