420, 422, 444 and what about these modes?

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

Why not?
try different options.

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?

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.

Kind Regards :slight_smile:

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:

@Frank @Terry The IR cut camera option in android is resetting upon reboot. Is this correct behaviour? Is it possible to make it remember the setting?

@Makro Hello , I confirmed with Terry, this option is not saved .

@Frank Is it possible to make it remember the setting? Hardcode it to stay in “IR-mode” as default? Now the regular camera is the default setting.

@Makro About open it as default , you need to ask @Terry for help

You can update the file screencontrol.rc on board.

# adb root
# adb remount
# adb push screencontrol.rc  /system/etc/init/screencontrol.rc
# adb shell sync
# adb shell reboot
