Hi
I write an application for Motorola Xoom tablet with Android 3.1 that
can scan multiple QR Codes in real time with it's camera and that
displays additional information in the display over recognised QR
Codes.
The recognition is done with the ZXing android app (http://
code.google.com/p/zxing/), I basically just changed the code of the
ZXing app so that it can recognise multiple QR Codes at the same time
and can do this scan continually, without freezing after a successful
scan like the original app does. So my app is basically the ZXing app
with continous scanning of multiple QR Codes.
But I'm facing a problem:
1. The recognition rate of QR Codes with the built in camera is not
very good. The ZXing app uses the pictures that it gets from the
camera preview. But these pictures do not have a very good
quality.
Is there any possibility to make the camera preview making better
quality pictures?
P.S. I also tried to make real snapshots with camera.takePicture()
to get a better quality, but it takes too long to take the picture
so the real time experience for the user is lost.
Any help is highly appreciated!
Thanks.
