bubo 0 Posted April 22, 2018 Getting dark the image my IMX291 NVP2441 camera board gets more and more purple coloured. From my part it could turn to BW now. Can I adjust in OSD the moment it start to turn to to BW? It it possible to prevent in OSD the purple coloration too? Share this post Link to post Share on other sites
TheF 0 Posted April 24, 2018 I had a similar problem not long ago. Turned out the IR-cut filter was defective. Most modern cameras use IR light to show night time images in black&white, but when at day-time having color images, the IR light needs to be blocked or else the IR light will be visible in dark areas (black areas will be purple-ish). To prevent this, the cameras has a mechanical IR cut filter, that physically places a filter in front of the imager. Share this post Link to post Share on other sites
