Canon M10 has a
18.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 6 processor. On the other hand, Sony A450 has a
14.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features Bionz processor.
Below you can see the M10 and A450 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon M10 and Sony A450 Cameras
Canon M10 and Sony A450 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the 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 Sony A450 sensors have been tested by DxO and the results show that A450 has a better overall score of 66, 1 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
Sony A450 ,
including hyperfocal distance.
