Images have poor resolution (native camera app)

[narayanaraoR]

I am trying to display the images captured using native camera app (https://github.com/rexstjohn/UltimateAndroidCameraGuide/blob/master/camera/src/main/java/com/ultimate/camera/fragments/NativeCameraFragment.java).
But the resolution seems to be poor even though my phone's camera device resolution is 13MP. How can I fix it?
Thanks in advance.
