10.0MP 1/2.3-inch (6.08 x 4.56 mm ) sized CCD sensor .
Below you can see the TG-630 iHS and SL202 sensor size comparison.
Sensor Size and Resolution Comparison image of Olympus TG-630 iHS and Samsung SL202 Cameras
Olympus TG-630 iHS and Samsung SL202 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Olympus TG-630 iHS
or the
Samsung SL202 ,
including hyperfocal distance.
