Takepicture () vs UIGetScreenImage ()

I'm trying to create QRCodeReaderfor a project our research team for iPhone is working on. After much research, I found a program called QuickMark. This program automatically scans QRCodes. What seems to be downloading UIImagePickerand reading data from the camera. I suspect that he is using UIGetScreenImageand taking a picture from the camera and decrypting it.

Now I tried to use the new method takepicture()from the 3.1 iPhone API, but it seems that it cannot do what it does above, which takes pictures every second or so, silently. Now I have heard that it UIGetScreenImagemay not be legal, and Apple will turn away and refuse access to your application if they use it. So my questions are:

a) Used QuickMark(or any other authorized application) with UIGetScreenImage(), and if so, it is legal and

b) would it be possible for the method to takepicture()do the same?

RedLaser definitely uses UIGetScreenImage (). A quick look at the characters in their library confirms this.
