Both Panasonic LZ20 and Fujifilm S9900w have 16.0 MP resolution sensors but Panasonic LZ20's sensor is 1/2.3-inch (6.08 x 4.56 mm ) and Fujifilm S9900w's sensor is
Since Fujifilm S9900w'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 Panasonic LZ20.
Below you can see the LZ20 and S9900w sensor size comparison.

Panasonic LZ20 and Fujifilm S9900w 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
Panasonic LZ20
or the
Fujifilm S9900w ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus ),
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.
