Nikon S9300 has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Samsung HZ10W has a
10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Nikon S9300's sensor provides 6MP more than Samsung HZ10W'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 S9300 and HZ10W sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon S9300 and Samsung HZ10W Cameras
Nikon S9300 and Samsung HZ10W 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.
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
Nikon S9300
or the
Samsung HZ10W ,
including hyperfocal distance.
