In many cases, it is tough to visualise the difference in sensor sizing just by going through a spec sheet. The visual here will give you a far better sense of the sensor measurements in the 1 S1 and E-PM2.

As you can see, each of the cameras provide different resolutions and different sensor sizing. The 1 S1 having a smaller sensor will make achieving shallower depth of field trickier and the Olympus E-PM2 will provide more detail with its extra 6MP. Greater resolution can also help you crop photos more aggressively.
