two errror for QR codes scanner : to auto zoom big for QR code for mobile user and wrong left right camera

i have QR codes scanning function for my website. as per image attached. But, the QR code image that my user is going to scan is much smaller.

i have seen some other applications which can auto zoom big for the QR codes. so that it can pick up the data easier.

i need you to make it auto zoom big.

another error is that the camera to scan QR code is always left right size wrong place. (when i move camera to the left, the QR codes move to the right) . please solve two errors
