Size of bitmap returned by camera via intent?

How do I get a bitmap with a certain (memory friendly) size from the camera?

I'm starting a camera intent with:

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
cameraIntent.putExtra("return-data", true);

photoUri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "mytmpimg.jpg"));
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, photoUri);        

startActivityForResult(cameraIntent, REQUEST_CODE_CAMERA);

I handle the result here:

//  Bitmap photo = (Bitmap) intent.getExtras().get("data");

Bitmap photo = getBitmap(photoUri);

Now if I use the commented line - get the bitmap directly, I get always a 160 x 120 bitmap, and that's too small. If I load it from the URI using some standard stuff I found (method getBitmap), it loads a 2560 x 1920 bitmap (!) and that consumes almost 20 mb memory.

How do I load let's say 480 x 800 (the same size the camera preview shows me)?

Without having to load the 2560 x 1920 into memory and scaling down.
