Since Fujifilm X30'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 SX130 IS.
Below you can see the SX130 IS and X30 sensor size comparison.
As seen above, Fujifilm X30 has a 2.1x Larger sensor area than Canon SX130 IS. 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.
