Both Canon A1300 and Olympus E-PL5 have 16.0 MP resolution sensors but Canon A1300's sensor is 1/2.3-inch (6.17 x 4.55 mm ) and Olympus E-PL5's sensor is Four Thirds (17.3 x 13 mm ).
Since Olympus E-PL5's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Canon A1300.
Below you can see the A1300 and E-PL5 sensor size comparison.

As seen above, Olympus E-PL5 has a 8.0x Larger sensor area than Canon A1300. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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
Canon A1300
or the
Olympus E-PL5 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.3-inch versus Four Thirds),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
