Both Samsung WB1100F and Nikon A1000 have 16.0 MP resolution sensors but Samsung WB1100F's sensor is 1/2.3-inch (6.17 x 4.55 mm ) and Nikon A1000's sensor is 1/2.3 (6.17 x 4.55 mm ).
Since Nikon A1000's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Samsung WB1100F.
Below you can see the WB1100F and A1000 sensor size comparison.

Samsung WB1100F and Nikon A1000 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 WB1100F
or the
Nikon A1000 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/2.3),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
