Are you in the UK / Europe or other 50 Hz zone of the world? If so you might want to try adding -fps 25 to the command line for the camera, as below:by fuzzyfelt » Thu May 16, 2013 2:46 pm
I tried out the camera this morning and there is a flashing band across the video that the camera records. I'm pretty sure this wasn't caused by static as I used our workshop (with ant-static wrist bands) when connecting the module.
I'll try the camera with another Pi this evening and will link to an example.
Has anyone else had a similar issue?
Well, the current max frame rate support is 30 so not sure why setting 90 made a difference.ppumkin wrote:I have the same problem. Like a blueish haze band across the entire screen in any size, 640x480 @ 90fps or default settings.
I tried the 25fps at HD and it reduced it allot. I have noraml halogen light bultbs and use original HTC 1A power supply running headless.
I was getting purple banding, yesterday when running at 30 fps, then changed to 25 fps and it was greatly improved. My lighting is line frequency (50 Hz) fluorescent tubes. At home I run electronic ballast compact fluorescents and have no problem at 25 or 30 fps.by dhid » Thu May 16, 2013 9:32 pm
I had a problem that was very similar to what you have described too and in my case it appeared that it was some interference being caused by the HDMI to VGA convertor I was using. When I connected to a proper HDMI display the problem went away.
Changing the power supply has solved the problem for me. The worst problems were noticed when I powered the Pi from the USB port on a KVM. Second place goes to the USB power supply I bought from CPC. A clean image was obtained using a laptop USB port for power.towolf wrote:I got heavy colored banding. I have two power supplies. After switching banding disappeared. Funnily they are both rated high enough. The Belkin Duo plug thing gives banding.
No fluorencent lighting, or any artificial light for that matter.
I have today done extensive testing using a Model B Rev1, Model B Rev2 (Chinese), Model B Rev2 (UK) and a Model A (UK). I have used 3 different power supplies, an HDMI to VGA Converter with VGA Monitor and an HDMI Monitor only.I had a problem that was very similar to what you have described too and in my case it appeared that it was some interference being caused by the HDMI to VGA convertor I was using.
