The question is not very precise. You want the emulator to use the real camera instead of this (http://www.tomgibara.com/images/android-camera-genuine.png), right ?

A few more details would be helpful, like which version of Android and of the SDK are you using.

yes! it's!
i using android SDK version 15 Platfrom 4.0.3
thanks for your report

Have you tried to edit the properties of the emulator ? (In the AVD manager, select your device, click "Edit") You should be able to change the "Back Camera" value.

yes,i have tried to edit.
So, in the AVD Manager, i show only "Camera Support", not found "Back Camera" at property Hardware.
when i change value of "Camera Support" to "yes", i can use my webcam when i click camera of emulator. But, when run my apps sample ZBAR/ZXING, i have a display same as (http://www.tomgibara.com/images/android-camera-genuine.png).
where can i fix it ???

Actually I use the Android SDK Tools rev. 21.1, and in my AVD properties window I have an option for Back Camera. Maybe try to update the SDK Tools to see if this helps.
Else, you can use this: http://www.tomgibara.com/android/camera-source
In my opinion, the best thing is still to use a real Android device with USB debug mode activated instead of the emulator. ;)
