Canon 10D has a
6.0MP APS-C (22.7 x 15.1 mm ) sized CMOS sensor . On the other hand, Nikon D200 has a
10.0MP APS-C (23.6 x 15.8 mm ) sized CCD sensor .
Below you can see the 10D and D200 sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 10D and Nikon D200 Cameras
Canon 10D and Nikon D200 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. Canon 10D and Nikon D200 sensors have been tested by DxO and the results show that D200 has a better overall score of 64, 7 points higher compared to 10D's score of 57.

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 10D
or the
Nikon D200 ,
including hyperfocal distance.
