Nikon 1 V1 has a
10.0MP 1-inch (13.2 x 8.8 mm ) sized CMOS sensor . On the other hand, Nikon 1 V3 has a
18.0MP 1' (13.2 x 8.8 mm ) sized CMOS sensor and features Expeed 4A processor.
Nikon 1 V3's sensor provides 8MP more than Nikon 1 V1'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 1 V1 and 1 V3 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon 1 V1 and Nikon 1 V3 Cameras
Nikon 1 V1 and Nikon 1 V3 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 Nikon 1 V1 has 81% larger pixel area compared to Nikon 1 V3, it has potential to collect more light on pixel level hence have less noise in low light / High ISO images.
DxOMark Sensor Scores
Both Nikon 1 V1 and Nikon 1 V3 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, 1 V1 has scored 54, 2 points higher than 1 V3.

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
Nikon 1 V1
or the
Nikon 1 V3 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1-inch versus 1'),
so compare them at the same framing rather than the same focal length.
Put the same focal length on the smaller sensor and it will show less depth of
field, not more, because it also crops tighter. The calculator shows the
full frame equivalent focal length for each body so you can match the framing.
