Generally, it is tough to see the difference between sensor sizing purely by looking at specs. The photograph underneath will help give you a better sense of the sensor measurements in the TG-870 and DP3 Merrill.

All in all, both of these cameras come with different megapixel count and different sensor sizing. The TG-870 using its tinier sensor will make achieving shallow DOF trickier and the Olympus TG-870 will give you more detail using its extra 1MP. Greater resolution will also allow you to crop images a good deal more aggressively. The more recent TG-870 will have an edge when it comes to sensor innovation.
