Autofocus when scanning QR code

I'm working on a BlackBerry app, and one of the feature is QR code scanning (will be used in cafes/restaurants).

Is there any way to make the camera autofocus the QR code?

I did some Googling, and found this: FocusControl

That looks like the one I'm looking for. Unfortunately, it's only available since OS 5.0. I wonder how to achieve the same thing on OS 4.5, 4.6, and 4.7.

Any suggestions?
