Samsung CL80 has a
14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon ELPH 530 HS has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 5 processor.
Below you can see the CL80 and ELPH 530 HS sensor size comparison.
Samsung CL80 and Canon ELPH 530 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 Canon ELPH 530 HS has 41% larger pixel area (2.81µm2 vs 1.99µm2) compared to Samsung CL80, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.
