Sony G3 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Fujifilm S9200 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor .
Fujifilm S9200's sensor provides 6MP more than Sony G3'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 G3 and S9200 sensor size comparison.
Sony G3 and Fujifilm S9200 have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Sony G3 has 59% larger pixel area compared to Fujifilm S9200, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
