Panasonic LX5 has a
10.0MP 1/1.63-inch (8.07 x 5.56 mm ) sized CCD sensor and features Venus Engine FHD processor. On the other hand, Nikon P7700 has a
12.0MP 1/1.7-inch (7.44 x 5.58 mm ) sized CMOS sensor .
Below you can see the LX5 and P7700 sensor size comparison.
Sensor Size and Resolution Comparison image of Panasonic LX5 and Nikon P7700 Cameras
Panasonic LX5 and Nikon P7700 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.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It 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. Panasonic LX5 and Nikon P7700 sensors have been tested by DxO and the results show that P7700 has a better overall score of 53, 12 points higher compared to LX5's score of 41.

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
Panasonic LX5
or the
Nikon P7700 ,
including hyperfocal distance.
One thing to watch when comparing these two: they have different sensor sizes
(1/1.63-inch versus 1/1.7-inch),
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.
