Both Fujifilm Real 3D W1 and Nikon L100 have 1/2.3-inch sized 10.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the Real 3D W1 and L100 sensor size comparison.

Fujifilm Real 3D W1 and Nikon L100 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Fujifilm Real 3D W1
or the
Nikon L100 ,
including hyperfocal distance.
