Reopen: Volatile exposure time / frame time

Could you check the exif of data for each frame.
You can reference to yuvJpeg sample code to use IImageJPEG that will store the exif data to the JPG header.

Ok, will try.

All files has same exif:


But images differ.

Wow, for this result what I only suspected is the antibanding.
Could you also set it to AE_ANTIBANDING_MODE_OFF

Antibanding always off.

What about under the normal light source?

I can make all necessary tests. What kind of lights you advice to exclude this case?

I made tests with simple led strip lights with driver 220v. Same issue detected.


You can see random floating zones with different exposure.
Anti-banding mod was 50hz, exposure time 2e6.

I think hardware (cameras/isp) can’t produce stable signal on small expo times <3e6.
Can Nvidia help to investigate it?

Maybe dump the PIXEL_FMT_RAW16 to confirm it.

Will try.
