Describe the bug
First of TnQ for this great lib. its simple and completely a clean solution.
However There i an annoying bug. When camera shows up screen lags periodically every second. I think the problem is that you are processing bitmap on the main thread and when the device config is weak this bug happens.

To Reproduce
Run this lib on the mid level devices

Expected behavior
Camera must work without lag and calculating and processing must be in background thread
