Both Kodak M575 and Kodak M590 have 14.0 MP resolution sensors but Kodak M575's sensor is 1/2.3-inch (6.17 x 4.55 mm ) and Kodak M590's sensor is 1/3-inch (4.8 x 3.6 mm ).
Since Kodak M575'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 Kodak M590.
Below you can see the M575 and M590 sensor size comparison.

As seen above, Kodak M575 has a 1.6x Larger sensor area than Kodak M590. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Kodak M575
or the
Kodak M590 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus 1/3-inch),
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.
