Hi, To implement a camera device in Android, you need to write a new Camera HAL layer. Now between the emulator and real device, there is different HAL for emulator and a different one for the real device. Now the emulator Camera HAL is basically something that generates a dummy video frame(like a virtual video device). In case of the device, the HAL would talk to V4L2(Video for Linux) framework to get camera frames.
You need to modify the emulator HAL and write your own one to support a webcam frame. The Android emulator is based on QEMU ARM virtualization, so I am not sure how much QEMU will allow for this activity. You need to communicate from a virtualized ARM platform to the native OS video routines(Video for Windows in case of windows). I am really nit sure if its possible through QEMU. Someone more familiar with QEMU could comment on this.
