Canon S110 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Digic 5 processor. On the other hand, Sony RX100 has a
20.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor .
Sony RX100's sensor provides 8MP more than Canon S110'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 S110 and RX100 sensor size comparison.
As seen above, Sony RX100 has a 2.8x Larger sensor area than Canon S110. 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 S110 and Sony RX100 sensors have been tested by DxO and the results show that RX100 has a better overall score of 66, 18 points higher compared to S110's score of 48.
