Samsung DV150F has a
16.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor . On the other hand, Canon A490 has a
10.0MP 1/2.3-inch (6.17 x 4.55 mm ) sized CCD sensor .
Samsung DV150F's sensor provides 6MP more than Canon A490'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 DV150F and A490 sensor size comparison.
Sensor Size and Resolution Comparison image of Samsung DV150F and Canon A490 Cameras
Samsung DV150F and Canon A490 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.
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 DV150F
or the
Canon A490 ,
including hyperfocal distance.
