Both Samsung Galaxy Camera 3G and Fujifilm S8400W have 1/2.3-inch sized 16.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the Galaxy Camera 3G and S8400W sensor size comparison.

Samsung Galaxy Camera 3G and Fujifilm S8400W have the same sensor sizes so they will provide same level of control over the depth of field when used with 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
Samsung Galaxy Camera 3G
or the
Fujifilm S8400W ,
including hyperfocal distance.
