Canon 1100D has a
12.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor and features Digic 4 processor. On the other hand, Nikon D7000 has a
16.0MP APS-C (23.6 x 15.7 mm ) sized CMOS sensor and features Expeed 2 processor.
Below you can see the 1100D and D7000 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1100D and Nikon D7000 Cameras
As seen above, Nikon D7000 has a 1.1x Larger sensor area than Canon 1100D. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in 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. Canon 1100D and Nikon D7000 sensors have been tested by DxO and the results show that D7000 has a better overall score of 80, 18 points higher compared to 1100D's score of 62.

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 1100D
or the
Nikon D7000 ,
including hyperfocal distance.
