Usually, its tough to picture the contrast in sensor dimensions only by viewing technical specs. The picture underneath should provide you a much better sense of the sensor sizes in the TG-820 iHS and K-3.

As you can tell, both of the cameras enjoy different resolutions and different sensor dimensions. The TG-820 iHS with its smaller sensor is going to make shooting shallow depth of field trickier and the Pentax K-3 will result in more detail using its extra 12MP. Higher resolution will also let you crop shots far more aggressively. The more aged TG-820 iHS will be behind when it comes to sensor innovation.
