Idea: CCD colour conversion to tube B&W cameras

[Aussie Bloke]

G'day all.

A little while ago I posted an experiment of mine which was to take two video stills of a subject using a vidicon B&W camera and CCD colour camera and superimpose them over each other to create a colour image with vidicon luminance and CCD chroma which can be viewed here http://videokarma.org/showthread.php?t=251215 . And I briefly talked about this being fron the idea of converting a B&W tube camera to colour using this method.

I have now expanded this tube/CCD colour camera idea of mine and have made a page on my site illustrating it in greater detail http://www.troysvintagevideo.741.com/tubeccdcolour.html .

I also have been thinking it would also be good to make the converted tube camera be interswitchable between 3 modes for versatility of use which are:
1: tube on, CCD on (luminance attenuated) for tube/CCD colour
2: tube on, CCD off for original tube B&W
3: tube off, CCD on (with normal luminance) for modern CCD colour

Anyways I have followed it up the tube/CCD idea with some diagram layouts of 3 general tube type cameras, the iconoscope, the image orthicon and the vidicon. The layout consists of a B&W tube, a colour CCD, a prism beam splitter to split the light to both image pickup devices and lenses and mirrors in between. I basically took the diagram of Fernseh's colour camera design consiting of a 3" IO and a colour striped vidicon from this page http://www.fernsehmuseum.info/fese-kc-33.html and have adapted the design as a basic platform to work off for my tube/CCD camera idea. I am not sure of what optical setup would be needed for the CCD so I left the the optic layout the same as the original, same thing for the colour matrixing method even though I think the green won't be accurately derived from the YRB when Y is a tube and RB is CCD.

I admit I don't know how practical or impractical this idea is but thought I'd put it out anyhow. I hope to somehow get the knowhow to put it into practice and either build a tube/CCD camera or modify a B&W tube camera with CCD and make it work! If anyone wants to put this idea into practice they are welcome and I totally encourage it!

Anyways here attached is a few diagrams of a tube/CCD colour layout which are for iconoscope, image orthicon and vidicon, these are featured on my page.
