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, Sony A380 has a
14.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor and features Bionz processor.
Canon 77D's sensor provides 10MP more than Sony A380'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 A380 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 77D and Sony A380 Cameras
As seen above, Sony A380 has a 1.1x Larger sensor area than Canon 77D. 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.
DxOMark Sensor Scores
Both Canon 77D and Sony A380 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, 77D has scored 78, 11 points higher than A380.

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 77D
or the
Sony A380 ,
including hyperfocal distance.
