Both Canon M10 and Leica M-E Typ 220 have 18.0 MP resolution sensors but Canon M10's sensor is APS-C (22.3 x 14.9 mm ) and Leica M-E Typ 220's sensor is Full frame (36 x 24 mm ).
Since Leica M-E Typ 220'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 Canon M10.
Below you can see the M10 and M-E Typ 220 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon M10 and Leica M-E Typ 220 Cameras
As seen above, Leica M-E Typ 220 has a 2.6x Larger sensor area than Canon M10. 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 M10 and Leica M-E Typ 220 sensors have been tested by DxO and the results show that M-E Typ 220 has a better overall score of 69, 4 points higher compared to M10's score of 65.

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 M10
or the
Leica M-E Typ 220 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(APS-C 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.
