Canon 77D has a
24.0MP APS-C (22.3 x 14.9 mm ) sized CMOS sensor and features DIGIC 7 processor. On the other hand, Fujifilm Z37 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Canon 77D's sensor provides 14MP more than Fujifilm Z37'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 77D and Z37 sensor size comparison.
As seen above, Canon 77D has a 11.8x Larger sensor area than Fujifilm Z37. 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.
