Part Number: TDA4AH-Q1

Tool/software:

Hi Experts ,

i am trying to do the AWB for AR0341 image sensor which in in 12 bit linear mode.SDK used: j784s4 version: 09_02_00_05

after the tuning i am getting below graphs and it is not coming as mentioned (linear)in the AWB tuning guide.

Because 12-bit linear RAW images are used, i am not loading the decompanding knee points in the DCC tool.

Request support to solve this issue

Thank you

Hi Ajay,

It seems like you did not set the black level correctly. Please set the black level and try AWB calibration again.

You may refer to the AWB plugin guide or the ISP Tuning Guide for additional information.

Best,

Chau

If you will use WDR mode in your application, it is better to do AWB calibration in WDR mode directly.
