Panasonic LX10 has a
20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor . On the other hand, Samsung GX-20 has a
15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor .
Panasonic LX10's sensor provides 5MP more than Samsung GX-20's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the LX10 and GX-20 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LX10 and Samsung GX-20 Cameras
As seen above, Samsung GX-20 has a 3.1x Larger sensor area than Panasonic LX10. 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.
DxOMark Sensor Scores
Both Panasonic LX10 and Samsung GX-20 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, LX10 has scored 70, 2 points higher than GX-20.

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 LX10
or the
Samsung GX-20 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1″ versus APS-C),
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.
