Both Canon G7 X and Panasonic ZS100 have 1″ sized 20.0 MP resolution sensors so sensor size and resolution is not a differentiator between these two cameras.
Below you can see the G7 X and ZS100 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon G7 X and Panasonic ZS100 Cameras
Canon G7 X and Panasonic ZS100 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.
DxOMark Sensor Scores
Both Canon G7 X and Panasonic ZS100 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, G7 X has scored 71, 1 points higher than ZS100.

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
Canon G7 X
or the
Panasonic ZS100 ,
including hyperfocal distance.
