Nikon D5000 has a
12.0MP APS-C (23.6 x 15.8 mm ) sized CMOS sensor and features Expeed processor. On the other hand, Canon 350D has a
8.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Below you can see the D5000 and 350D sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D5000 and Canon 350D Cameras
As seen above, Nikon D5000 has a 1.1x Larger sensor area than Canon 350D. 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
Both Nikon D5000 and Canon 350D 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, D5000 has scored 72, 12 points higher than 350D.

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 D5000
or the
Canon 350D ,
including hyperfocal distance.
