10.0MP 1/1.63-inch (8.07 x 5.56 mm ) sized CCD sensor and features TruePic V processor. On the other hand, Canon G15 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor and features Digic 5 processor.
Below you can see the XZ-1 and G15 sensor size comparison.
Olympus XZ-1 and Canon G15 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. Olympus XZ-1 and Canon G15 sensors have been tested by DxO and the results show that G15 has a better overall score of 46, 12 points higher compared to XZ-1's score of 34.
