Camera image is too dark

juanm4 opened this issue 7 years ago · 4 comments

Hi, I am using this library to read qr codes.

I have realized that when I open QRCodeReaderView variable the image of the camera appear too dark, in contrast to the image of the default camera app of my phone.

What is going on? Why the image of QRCodeReaderView is darker than default app camera?

Thanks in advance!

I have read that I must disable autoexposure, and set it manually but... How Can I do this in this library?

I had put the CAMERA permission in the manifest file, but the brightness is too low.

So, any other ideas?

Thanks!

We are facing same problem too. Can this be marked as important? Compared to regular device camera app, image is much better and brighter on default one, and this darkness prevents code reading.
