Oftentimes, it is very hard to visualise the difference in sensor measurements just by going through a spec sheet. The visual below should give you a clearer sense of the sensor sizing in the TG-820 iHS and K10D.

As you can see, each of the cameras come with different resolutions and different sensor measurements. The TG-820 iHS featuring a smaller sensor will make achieving shallow depth of field trickier and the Olympus TG-820 iHS will show extra detail as a result of its extra 2MP. Greater resolution will also let you crop images a good deal more aggressively. The more modern TG-820 iHS is going to have an edge in sensor tech.
