Usually, its difficult to picture the difference between sensor dimensions purely by looking at technical specs. The picture below may offer you a more clear sense of the sensor sizes in the TG-630 iHS and DP1.

As you can tell, the 2 cameras come with different megapixel count and different sensor dimensions. The TG-630 iHS using its tinier sensor is going to make achieving shallower DOF more challenging and the Olympus TG-630 iHS will give you greater detail because of its extra 7 Megapixels. Greater resolution can also let you crop images a good deal more aggressively. The younger TG-630 iHS provides an edge with regard to sensor tech.
