AM62A7: AWB is not effective

Hello Mr. Meng,

Can you share the YUV images after the ISP, both when you have AWB and when you don't have AWB? I'd like to see the difference.

Thank you.

Hi Meng,

Here is my awb pic and step and result

Thanks for sharing!
Your steps, raw and xml files look good for a linear sensor.

Could you please change the "70" below to 100 if your sensor works in linear mode?

BTW, you have DCC ID = 219 in your xml file.

Please confirm if your DCC ID is really 219 for your sensor.

oh , my mistake

this camera sensor is work on hdr4 mode

how do I change config for hdr sensor?

The raw images your shared seem in linear mode.
It is OK to do AWB calibration with linear images while choosing the correct pre-compression gamma value (70 if it is 0.7 gamma).

This is decided by your sensor driver.

Jianzhong Xu may be able to help you with the gstreamer settings.

You can enable WDR processing on the ISP using a flag "wdr_enabled" in Gstreamer.

For example:

gst-launch-1.0 \
v4l2src device=/dev/video-imx390-cam0 io-mode=5 ! video/x-bayer, width=1936, height=1100, framerate=30/1, format=rggb12 ! queue leaky=2 ! \
tiovxisp sink_0::device=/dev/v4l-imx390-subdev0 sensor-name=SENSOR_SONY_IMX390_UB953_D3 dcc-isp-file=/opt/imaging/imx390/wdr/dcc_viss_wdr.bin \
sink_0::dcc-2a-file=/opt/imaging/imx390/wdr/dcc_2a_wdr.bin format-msb=11 wdr-enabled=true sink_0::pool-size=8 src_0::pool-size=8 ! queue ! \
