Nikon S31 vs Nikon S9100 Sensor Comparison

Often, it is hard to picture the contrast between sensor sizing purely by reading through specifications. The visual underneath might offer you a much better sense of the sensor sizes in the S31 and S9100.

To sum up, each of the cameras provide different resolutions and different sensor sizing. The S31 with its tinier sensor is going to make achieving shallow depth of field more difficult and the Nikon S9100 will give more detail with its extra 2 Megapixels. Greater resolution can also enable you to crop photos more aggressively. The newer S31 should have an advantage in sensor technology.
