After executing the AWB tuning of the DCC tool, the screen turned green.

Please tell me how to solve this problem.

Hi Meng,

Thanks for sharing the XML files. I noticed you had a gamma in your tuning:

// AWB tuning parameters

20, // luma_awb_min

60000, // luma_awb_max

3500, // low_color_temp_thresh

100, // apply_rgb_adjust

70, // R_adjust(percent)

90, // B_adjust(percent)

Please set the WDR Gamma to 100 in the AWB tuning -> Advanced params:

This is the gamma valued used for WDR sensors. It should be set to 100 for linear sensors like IMX219. Please refer to the AWB Plugin User Guide:

Jianzhong
