ZBarReader QR Code detection time

In my app i'm using ZBarReader, and i can able to detect the QRCode and BarCode using the code 

ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.readerDelegate = self;
reader.supportedOrientationsMask = ZBarOrientationMaskAll;

ZBarImageScanner *scanner = reader.scanner;
// TODO: (optional) additional reader configuration here

// EXAMPLE: disable rarely used I2/5 to improve performance
[scanner setSymbology:0 config:ZBAR_CFG_ENABLE to:0];
[scanner setSymbology: ZBAR_QRCODE
               config: ZBAR_CFG_ENABLE
                   to: 1];

reader.tracksSymbols=YES;
reader.readerView.zoom=1.0;


// present and release the controller
[self presentModalViewController: reader
                        animated: YES];
[reader release];

But it detects the code only when i make my camera much closer to the barcode, it's not detecting when i keep my camera little far from barcode Is there any property to scan the code very Quickly even when i have camera far from barcode..

Solution

  • Basically Zbar reader depends on the camera resolution of the device but still try using

    reader.readerView.session.sessionPreset = AVCaptureSessionPreset1280x720;

    adjust AVCaptureSessionPreset1280x720 .May this helps.
