It is possible to achieve. You should define a class that handles the Camera object, as in calls on Camera.open() and such. Don't provide the camera object with the following lines in order to disable the preview - 

mCamera.setPreviewDisplay(mTargetHolder);

Where mTargetHolder is the SurfaceView.

If you want to receive frame callbacks you can implement the Camera.PreviewCallback interface.

Now before you call on camera.startPreview() register you callback handler using setPreviewCallbackWithBuffer(Camera.PreviewCallback). Camera reference

With this frame data you receive from the callback you can do what ever you want. just remember that it is a raw data format. See also Camera.PictureCallback usage if you wish to take a picture.

I hope this helps. (even if not relevant)

Cheers
