14.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized BSI-CMOS sensor .
Below you can see the HZ10W and WB250F sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung HZ10W and Samsung WB250F Cameras
Samsung HZ10W and Samsung WB250F 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 HZ10W
or the
Samsung WB250F ,
including hyperfocal distance.
