Both Olympus VH-515 and Samsung TL100 have 1/2.3-inch sized 12.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the VH-515 and TL100 sensor size comparison.

Olympus VH-515 and Samsung TL100 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 VH-515
or the
Samsung TL100 ,
including hyperfocal distance.
