Suddenly in lightburn i see black and white

I have been using a USB video camera for months which is recognized as SMI.
I think it’s an ov 5647 that has always worked perfectly in color.
for a few weeks now I’ve only seen the preview in black and white despite the lightburn settings being in color.
using the windows tool for the webcam I see it working perfectly in color.
otherwise it is perfectly calibrated and functional but it was nice to be able to see the color work plan as it was before.

please do you have any suggestions?
I didn’t change anything, just at a certain point the color was disappeared.
today I did several tests including a new calibration and everything works except the color.
the LB cam settings in the settings menu are set to color

Just to confirm, it’s not due to lighting conditions that the image may just appear to be black and white? Just want to get anything obvious out of the way. Some cameras have low color sensitivity.

If that’s not the issue, have you tried connecting to a different USB port? Try a USB3 port if available even if it’s a USB2 device.

If that doesn’t work, have you tried toggling Camera View in Settings to Black and White and then toggled back to Color?

Thanks, it happens to me on all usb ports and the lighting is good, always been the same.
I have not tried to switch from black and white to color but in the windows utilities, on lightburn setup nothing changes, it is always in B / W
Today I will do more tests and thank you.
it doesn’t even make sense to think about changing the camera because it works in color on windows so I rule out it being faulty.

I can’t fix the black and white camera problem.
the cam works well, from windows it is in color, I am attaching a screenshot of windows.
I also attach a screenshot of lightburn where you can see the color settings and my cam which is black and white.

from windows 10 utility webcam program

from my lightburn

this glitch happened suddenly, i didn’t install anything or change my pc or other settings, just overnight i started seeing only in black and white.

obviously I tried to change usb ports and exit and re-enter lightburn changing settings but it always remains as seen in the photo.

lightburn last version 1.3.01

Do you have another camera you can test to see how the live image works? Curious if the issue would apply to all cameras or is somehow limited to the one camera.

I remember reading awhile ago that deselecting the camera restarting LB and reselecting the camera fixed a few problems. It was a few versions ago. Might be worth a try.

thank you for the help.
no at the moment I don’t have another camera but I can see it in color both in windows and on a second serial device, if it were broken I would see it in B/W elsewhere too.
I tried a LB version downgrade but nothing changes.
I tried to do the calibration several times and frankly I give up trying this long route again.
I have no more ideas, I’ll keep it in B / W maybe one day it will unlock something like the day that suddenly became B / W

I have a friend who has a 5mp twin to mine… I asked if he could lend it to me to test, it’s the only card left for me to play.

I was just talking about in the camera window. Select none for camera then reboot LB. Reselect the camera and see what happens. I remember it fixing other issues like forced zoom etc.

yes, but it doesn’t work. I can also restart on laptop system wecam, or none but once I select the SMI it is always in black and white.
I use it without problems but before I saw it in color.
I don’t understand where the problem is, if it comes from my laptop Dell M6600, from the cam that works in color on win 10 (I would like to exclude it) or from LB.

tonight I’m going to a friend and I’m taking laptop with me, we’ll connect his cam which is a twin or very similar to mine.
We will first check if its showing in color on his LB machine, then I test it on my laptop.

Unfortunately I still haven’t been able to test on a different PC.
today I did an online test, on my win 10 all the programs that use the camera let me see it in color except Lightburn.
these are the test results, i don’t know if they can hide some clues to solve this problem.

Are you able to use Custom Camera System in Edit->Settings? Curious if that would make a difference.

changing to a custom camera system this happens: the view is distorted but it is in color.

going back to the preset camera system and saving/restart LB comes back correct in shape but not in color.

You will likely need to recalibrate lens and alignment.

thanks for the suggestion.
I set the custom camera system and redid the calibration.
seems finally fixed.
I’d like to understand why he was fine with the preset camera system for 4 months in color and then one day it suddenly went black and white.
anyway thank you very much, now i have a solution.
