Usually, its difficult to imagine the difference in sensor measurements purely by going through a spec sheet. The graphic here might offer you a more clear sense of the sensor dimensions in the TG-4 and DP1x.

As you can see, both of those cameras feature different megapixels and different sensor measurements. The TG-4 due to its smaller sensor is going to make shooting bokeh trickier and the Olympus TG-4 will provide more detail as a result of its extra 11 Megapixels. Higher resolution will also help you crop photographs way more aggressively. The more recent TG-4 should have an advantage with regard to sensor technology.
