Samsung ST93 has a
16.0MP 1/2.3-inch (6.16 x 4.62 mm ) sized CCD sensor . On the other hand, Canon D20 has a
12.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CMOS sensor and features Digic 4 processor.
Below you can see the ST93 and D20 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung ST93 and Canon D20 Cameras
Samsung ST93 and Canon D20 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
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
Samsung ST93
or the
Canon D20 ,
including hyperfocal distance.
