TDA4VH-Q1: TDA4VH-Q1: AWB discuss : white objects in highlighted areas turn greenish

Kuei lin Chu

Part Number: TDA4VH-Q1

Hi TI Expers,

AWB WDR mode has a greenish in the highlighted area, which basae on j784s4-evm-08_06_00_14、J721e_evm and DCC tool TDA4VH v3.0. Our image sensor is IMX390
We have increased luma_awb_max to 65000 and still greenish

65000, // luma_awb_max

Attach the XML of AWB  IMX390_awb_alg_ti3_tuning.xml



May I ask what settings need to be checked for the phenomenon of greenish highlights?


Thank you


David

    Hi,
    

    That looks like an issue of the Sony sensor rather than AWB.
    

    Sony mentioned that calibrating sensor settings with camera/lens module carefully may avoid this issue.
    I don't know the details on the sensor side.
    Please contact your local Sony support for more information.
