Casio EX-FH25 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor . On the other hand, Canon SX60 HS has a
16.0MP 1/2.3 (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 6 processor.
Canon SX60 HS's sensor provides 6MP more than Casio EX-FH25's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the EX-FH25 and SX60 HS sensor size comparison.
Casio EX-FH25 and Canon SX60 HS have the same sensor sizes so they will provide same level of control over the depth of field when used with same focal length and aperture. On the other hand, since Casio EX-FH25 has 41% larger pixel area compared to Canon SX60 HS, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
