Hi Everyone,

we are using sony IMX678 on a hisilicon soc and met image issues. I am wondering if anyone can give any suggestions.

We used IMX678 DOL-HDR with 2 line to 1 mode on hi3559V200 and the image is abnormal as below.

the sensor has been brought up but image is wrong. we tried 2 frames to 1 and it works normal.

The log is as below. Since the values are all zero, it seemed the lanes are correct but image just can’t get right.

Hi @ideastorm and welcome to the NVIDIA developer forums.

Can you give a bit more context here? To which NVIDIA HW are you trying to integrate the IMX678?

Hi Markus,thank you very much for your attention to our bug issue :-))

The hardware we are using is not Nvidia but Hisilicon Hi3559V200. We can’t find resourceful help in China so I am trying my luck here.

So hisilicon provide 2 kinds of WDR. One is 2 frame to 1 and we have worked it out. But ISP suggested such mode will cause moving shadows. He suggested using 2to1_LINE WDR mode. But our system engineer met image issue as I showed above.

The linear mode also works fine.

We are wondering if anybody know if IMX678 supports 2to1_line mode?

Just to clarify.

These are NVIDIA developer forums. If your HW issue is related to the NVIDIA Jetson platform, then we have a lot of experts that are able to help.

But it is very unlikely that you find discussions on unrelated third-party Hardware manufacturers.

You can try to search for “IMX678” and you might find developers using that module on a Jetson board.

Maybe that helps.

Thanks for your reply and I am sorry for the disturb.

I checked all posts about IMX678 and did not find if it supports 2to1 Line mode.

We would appreciate it a lot if anybody has experience with IMX678 DOL HDR with 2to1 line mode.
