a few rusty gears are turning---my knowledge on the ccd's, and whatever else that is required to capture images in these digital wonders, is very elementary, but im wondering is there a way to take two dvx's apart and wire in multiple ccd's into one dvx and allow them to capture one image? Would this be feasible (cheaply and efficiently), what would be required, and could it be done (theoretically at least)???

any tech Einsteins out there who can help? :thumbsup: :thumbsup: :thumbsup:


yeah cuz!

It's been done to create a 3-d imaging system. I'm sure somebody out there can throw you a link. It was made by syncing 2 dvx's to get 2 images which were then matted together in post or something to that extent.

monte- That 3D thing they made is cool. I'd like to play with that.

What would be the benefit of creating one image from 6 CCDs? You wouldn't gain any resolution from it.

so the bigger the ccd means more rsolution??not quantity? surely it must do something if you combining all 6 ccds.....


just a whim

There are a few problems - your resolution is capped out based on what codec you are using. With the DVX is goes through the dv codec wich is a 5 to 1 shitty shit shit ... well you get the idea, thats why when you try to greenscreen stuff its harder to get good results than with a camera that is using a color space of, say (uncompressed, meaning no codec) 4:4:4 vs the 4:1:1 of DV.

That's the advantage of taking the image straight from the CCDs and straight into your computer for that type of stuff. Right now its something like this:

Image hits lense - degrades
Image is picked up by CCD's - degrade
Put through in camera stuff (ie pedestal, cinegamma) - degrade
Put through DV codec - degrade

So what would be ideal would be going from straight from the lense to the finished medium. That would ofcourse be film - however there is a thing called Andromeda i believe which basically cuts out some of those steps, I'm assuming it grabs the image off the ccds before its processed and put through the DV codec, however it's still limited by the 1/3 ccds.

What would be ideal would be 3 foveon chips, which - as I understand operate like 3 normal ccds. 1 foveon has all R G and B rather than having 1 color each. So that means if you got 3 of those in camera that were larger (ie 2/3) each one could handle something specific in another area - perhaps: highlights, mids, and deep shadows, or something like that, thus increasing the latitude.

Then this signal would be sent straight to the harddrive or some sort of solid state media and you could take that back, no drop outs and straight unmolested data.

Then again, what do I know, I drink gasoline.

yes i've heard of the digitally enlightening product that is Andromeda

Woah..u can link up your CCDs? ive never heard of such a thing..thats freakking aweesome!!....someone find the links...i got 4 old digital cameras layin around i might wanna mess around with...

gkumar...your link aint workin bro...

hopefully this can work!! but check out the picture quality of these high end ccd's :thumbsup: :thumbsup:

Those pics are madddddddddddddddd nice resolution.

those are 1/3 CCDs? nooooo way....how many CCDs were used?

...or instead of doin that...get a 9.0 megapixel camera and make amazing shots with a realy nice lens on them...that oculd work too....soo many typos...too lazy to backspace...

Jarred shot a segment in "Art History: using two DVX's side by side to make a mega-widescreen picture. That's sort of a no-hardware way to do something that's, well, pretty much not like what you're asking... don't know why I thought of it...

Wouldn't that cause a problem for objects near to the lenses having a different viewing angle.

I used the same technique to achieve a panning time-lapse shot once, but had to ensure there was nothing moving near to the front of the cameras.

wow those pics are really really perfect!

they are very great, aren't they? but can we really hook up multiple ccds to achieve something far greater than what the DVX can do at the moment, or is that just an ignorant tangent?

i would really like to know. Because my train of thought is: if there is more ccd's capturing data and streaming into one image--there would be more image data for that one image....quantity compensates for size of the ccd's---right????j

i can get my hands on a few old dvx ccd's that i can take apart- but i need more opinions?

i dont understand....a mega widescreen? can you explain?

a mega widescreen...think of it as Super Letterboxing in a way....its at such a wide angle that you have to make the image really small in height but in width its verry long so you see more image....imagine 16:9 ratio but double the width.....

am i right Barry?

Well, no, what they did I guess was make a super wide screen and then they showed a window within that screen, so you had a full-screen, full-res picture but they could pan back and forth within it (on a basketball court, for the opening credits).

oh - okay thanks


so this idea is a no go, economically speaking, am i understanding correctly????

damn, i should go to a ccd forum or something
