BTW, guys while running NPU demo on Ubuntu with MIPI camera, I can again see that unclear blueish tint which wasn’t there when using guvcview on RGB24 format. Can you help me to see clearer image while running NPU demo YOLOv3.

44

settings accidentally reset?

45

No, even previously I had the same issue with NPU demo YOLOv3. the blueish image on it is not new. I can resolve it in Desktop mode by using guvcview but how can I get clear image while running YOLOv3 NPU demo on MIPI camera?

46

420, 422, 444 and what about these modes?

47

Don’t know. Never tried it. Why do you want me to test for these?

48

Why not?
try different options.

This is for Android 1080p

Hey @Frank, Thanks for your reply. The image while using NPU demo for MIPI was looking similar to this image only(posted above) But this one is from android as currently I’m on android. If this image doesn’t help you, I’ll reflash Ubuntu and run the demo again for you.

Thanks :slight_smile:

@Frank, I think the IR cut filter is enabled by default, Can we disable it?

57

Hey @Frank, I have attached the Image while running YOLO demo below. Kindly see to it and please help me to make that camera feed look clearer and disappear this blueish tinge. I really hope that it is a solvable issue. I am using MIPI camera in while running this demo.

Thanks @Frank for the command. I can see clear image now. The issue is IR cut right? How can I change the demo code to disable it?

Ohk @numbqq added support for IR cut just now here: NPU Demo and source code

Also, Android camera app blueish video feed was solved by flashing new Android Pie ROM posted by @Terry here: VIM3 Android Pie V200624 ROM Release

So, I got the solution for this.

Thank you everyone for your support :slight_smile:
