ASI224MC missing green and blue? was created by Boris Pruessmann

Hey,

I am struggling to get a color picture from my ASI224MC. Looking at the histogram, it seems that the file only contains the R channel. The settings are pretty much set to default, and I haven't found anything obvious so far. I'll attached an image as reference.

Help appreciated.

What was the video format in the ASI driver when you took this image? RGB?

Yes, that was RGB24. The RAW formats are also not showing any color.

This is indeed an odd error. Do you have other ASI cameras you can test? The ones I have do not exhibit this issue.

No, I don't have another ASI camera. But I do have a different system to test on ;)

MacBook:
ASICAP - Image is in color
EKOS - Image is in color

RPi4:
EKOS - Image is b/w

The version of the ZWO INDI driver is exactly the same between MacOS and the RPi. The ASI SDK is older on the Mac though: 1, 14, 0315 vs. 1, 14, 0715.

Can you compile INDI on rpi4 and use the older SDK to see if that makes a difference? It was changed in this PR: github.com/indilib/indi/pull/988

You can perhaps compiled at any older commit or just use the previous API and check it out? If you confirm it's an API issue, I'll inform ZWO about it.

I've reverted to the previous SDK version, confirmed that the build worked under "General Info", but the image is still B&W. Next best thing will probably be to revert the whole INDI build to the same version that is successfully running on the Mac... Alternatively, doing the opposite, trying to get a newer version for the Mac...

It's a good idea to do git bisect to find what broke this exactly.

Good suggestion. But first I need to find a version that is running correctly on my RPi4. I just hope that this problem is not caused by one of the dependencies...

At some point Ekos defaulted to resource constrained mode on Raspberry Pi and wouldn't debayer color images unless explicitely enabled unlike on Mac / PC. Worth checking that too.

D'uh. Auto Debayer it was... Thanks for that tip.

Having said that... Video is still being display B&W. Is that expected?

Auto-debayering video is not yet implemented :-(

Maybe this is something you'd be interested to work on? It's C++ and Qt ;-)
