Hello,
i've created a labview program with NI Vision.
I acquire a picture with a webcam and then check it if there is a cube and get the position of the cube.
The problem is each time i run the inspection the acquired picture gets darker.
I've got the same problem when i open the inspection with NI Vision.
The cable of the Webcam is about 1.5 meters long and i enlarged it with another 2 meter long cable to an total length of 3.5 meters, earlier i was using a cable with an total length of 4.5 meters with the same problem.
When i use other software(vlc player) to just acquire a picture the picture dont change.
I've attached a picture that shows the problem and the NI Vision inspection that i created.
I'am using this webcam: ELP 1080P 2MP 30fps JPEG 1920 x 1080 Full HD Mini USB Box CMOS Kamera mit 2.8-12mm Vario Objektiv
