Canon ELPH 100 HS has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 4 with iSAPS technology processor. On the other hand, Canon Elph 115 IS has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor and features DIGIC 5 processor.
Below you can see the ELPH 100 HS and Elph 115 IS sensor size comparison.
Sensor Size and Resolution Comparison image of Canon ELPH 100 HS and Canon Elph 115 IS Cameras
Canon ELPH 100 HS and Canon Elph 115 IS 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 100 HS has 32% larger pixel area compared to Canon Elph 115 IS, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
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 ELPH 100 HS
or the
Canon Elph 115 IS ,
including hyperfocal distance.
