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, Canon 1000D has a
10.0MP APS-C (22.2 x 14.8 mm ) sized CMOS sensor .
Below you can see the 1100D and 1000D sensor size comparison.
Sensor Size and Resolution Comparison image of Canon 1100D and Canon 1000D Cameras
Canon 1100D and Canon 1000D 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. On the other hand, since Canon 1000D has 20% larger pixel area (32.60µm 2 vs 27.00µm 2 ) compared to Canon 1100D, it has larger pixel area to collect light hence potential to have less noise in low light / High ISO images.

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
Canon 1000D ,
including hyperfocal distance.
