I have integrated google vision in my project as shown in below post: http://code.tutsplus.com/tutorials/reading-qr-codes-using-the-mobile-vision-api--cms-24680

Everything looks fine except the camera view brightness . The camera view here is very dark when comparing with my actual android camera app.

Please let me know if i can increase the brightness of the camera and turn on any low light settings. Thanks .

I had the same problem. Adding .setRequestedFps(15.0f) while Building CameraSource resolved my problem. Seems like the fps count has something to do with brightness. My builder looks like that:

CameraSource cameraSource = new CameraSource.Builder(getActivity(), barcodeDetector)
                .setFacing(CameraSource.CAMERA_FACING_BACK)
                .setRequestedPreviewSize(1600, 1024)
                .setRequestedFps(15.0f)
                .setAutoFocusEnabled(true)
                .build();

  • Thanks for the reply, I used xzing later for barcode scanning. But this is good information. – VaV Jul 19 '17 at 02:31
  • I've tried zxing too, but for me google vision is better. It's just easier to implement and you can scan barcodes in any orientation :) – TheD3luxed Jul 20 '17 at 09:10
  • This works brother, can you help how to set exposure parameters to auto adjust the brightness depend on devices? – Md. Rejaul Karim Dec 09 '20 at 08:13
