Rgb Bayer osc flter?

#1

Post by ruthlessaz »


I know this may be a dumb question.....but is there a "one shot color" filter out there, for monochrome cameras? Just curious.

Thanks

I don't how that would work exactly but there is a way to convert mono images to RGB and calibrate them using some kind of colour calibration to a reference image. For instance, PI's Photometric Color Calibration might do something like that.

The problem with converting a mono camera to OSC via a filter is that the individual pixel filters have to be perfectly matched to the pixel sensors. The only way that can happen is to have the filter in physical contact with the sensor. The alignment of colours to pixels must be perfect. Pixel sizes on typical sensors are in the order of 3-6 um, so the alignment of the filter would have to be more accurate than that. That is a lot to ask for an add-on filter.

It would likely be easier and cheaper, and certainly more do-able, to just buy another camera that is made as OSC at the factory.

Or get a filter wheel and do regular RGB processing.

Thank you for the help here, I figured as much. I have a 1600 mobo, with filters, but I feel it's time consuming etc. Maybe thinking if one day getting a osc
