Canon G9 X has a
20.0MP 1″ (13.2 x 8.8 mm ) sized BSI-CMOS sensor and features DIGIC 6 processor. On the other hand, Panasonic L10 has a
10.0MP Four Thirds (17.3 x 13 mm ) sized CMOS sensor .
Canon G9 X's sensor provides 10MP more than Panasonic L10'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 G9 X and L10 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon G9 X and Panasonic L10 Cameras
As seen above, Panasonic L10 has a 1.9x Larger sensor area than Canon G9 X. 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 Canon G9 X and Panasonic L10 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, G9 X has scored 63, 8 points higher than L10.

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
Canon G9 X
or the
Panasonic L10 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1″ versus Four Thirds),
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.
