Panasonic ZS45 has a
16.0MP 1/2.33 (6.08 x 4.56 mm ) sized CMOS sensor . On the other hand, Canon SX510 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the ZS45 and SX510 HS sensor size comparison.

Panasonic ZS45 and Canon SX510 HS 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
Panasonic ZS45
or the
Canon SX510 HS ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/2.33 versus 1/2.3-inch),
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.
