Both Canon G1 X II and Panasonic LX100 have 13.0 MP resolution sensors but Canon G1 X II's sensor is 1.5-inch (18.7 x 14 mm ) and Panasonic LX100's sensor is Four Thirds (17.3 x 13 mm ).
Since Canon G1 X II'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 Panasonic LX100.
Below you can see the G1 X MII and LX100 sensor size comparison.
As seen above, Canon G1 X II has a 1.2x Larger sensor area than Panasonic LX100. 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 G1 X II and Panasonic LX100 sensors have been tested by DxO and the results show that LX100 has a better overall score of 67, 9 points higher compared to G1 X MII's score of 58.
