Incorrect colors - greenish image
laheller opened this issue · 1 comments
On my Samsung Galaxy A54 5G device when I try to convert from YUV420 to RGBA, the result image is however correct, but it has a kind of green tint. The way how I do the convert is inspired by the HDRViewFinder demo application's renderscript kernel code.
The HDRViewFinder demo app itself gives correct image & correct colors without green tint, but in my case on Xamarin.Android platform I unfortunately cannot use custom renderscipt, because it is not supported.
More info & my sample code in the following stackoverflow post:

I saw your comments and example codes at many many similar questions, you maybe know the reason or just give me some hints, what I am doing wrong.
Problem solved, however not sure, why this helped:
Before taking the YUV420 format picture I had to change camera2 WhiteBalance settings from Auto to Fluorescent.
