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, Leica Q has a
24.0MP Full frame (36 x 24 mm ) sized CMOS sensor and features Maestro II processor.
Below you can see the G9 X and Q Typ 116 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon G9 X and Leica Q Cameras
As seen above, Leica Q has a 7.4x 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
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Canon G9 X and Leica Q sensors have been tested by DxO and the results show that Q Typ 116 has a better overall score of 85, 22 points higher compared to G9 X's score of 63.

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
Leica Q ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1″ versus Full frame),
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.
