after taking test shots with my Canon 10D and the new SI3300RGB I have found that the range on the 3300 is about like the 10D in RAW mode..this is good news to my ears...anyone else?

Also it seems that to show the same amount of color I must boost the 3300 about 45% on the saturation level..not sure why but this chip seems to be less color heavy then others..not as bad as IBIS but not as good as Canon 10D...over all good stuff!

I agree on the camera case, nice. I read you wanted to do a case, but I couldn't find where you said that.

I was thinking of doing a few cases, myself, but haven't got around to it and finding manufacturers. I have most of the specs and components in my head (very good virtual reality modeller ;). Actually i was talking to somebody, but they seemed to suddenlly dissapear and I haven't heard back, whatever happened to Rai??


Steve N

I agree about the preveiw, we are dealing with GBGR any way, that is close to RGB pixel. If you want a bit more resolution for focusing I suggest that with an RGB LCD with RGB cells in the pixels you can address the subpixels (so a 640*480 display becomes 1920*480 focusable display).

Another suggestion for the preview display, is to add a instant magnifyer feature for focusing, where you touch a button and the centre comes up double size while you hold it.

<<<-- Originally posted by Steve Nordhauser :That might work nicely with the VGA touchscreens - 720p is 1280x720 so a 640x360 preview image leaves room for some menu controls. -->>>

Obin

Is the 3300 presenting more natural colours, and the Canon boosting them?

I think the 3300 is exciting, not because it is the best thing since sliced bread, but because it is a camera we can use (without problems). I look forward to seeing it, the footage from the previouse model looked exciting, this should be more.

Rob I would, and we can only try. It's not going to be simple or easy, but a rejection should come fast, so it is worth a go, otherwise we won't know. Just look at how Bill sold IBM his non existent DOS, I know some of the history that lead upto that. They turned down buying Atari, doing CPM, doing 68000 (probably linux), they even had a crack at buying Apple, but Bill pulled it off. He out did those companies, despite not having their power, money, infrastructure, or reputation, he even had to go and buy the OS from somebody else. I hate to say it, but truely a victory for the little guy (at that stage). If he can do it, we should be able to get some help in return for a million dollers worth of marketable publicity. Something like this should be able to hit the news lines of every major IT news site and magazine, not to mention the video sites and magazines. What we are saying going to them, is that we are here, and we want to make something of it, permanmently.

The world out there is a jungle of competing politics and business interests, even in companies, that get mixed up and stirred around. With certain people, at a certain place, in certain circumstances and times, things are possible, but we won't know until we put the spoon in and pull it out.

Wayne,

I think there's something you're overlooking in this whole situation when you're thinking of pitching this idea to a big company.

Money spent on marketing

These are all companies that are owned by shareholders. They're not going to be spending a ton of money on projects that they then have to turn around and market for millions of dollars to get sales. How much money do you think Sony spends on marketing? How about Panasonic?

With big company $$$'s comes big company beaurocracy, big company ideas, much of them the antithesis of what we're trying to do here.

Why do you think Linux is doing so well as an underground movement, finally catching the attention of the big boys (IBM)? This stuff that we're doing is grassroots stuff, not big company consumerism.

Now to buiseness :-)

Obin, how 'bout posting some pics from the new 3300 :-)

BTW, were these new pics from your new capture app?

gone for a few days on vacation..hold down the fort for me!

I will be Mountain Biking in the North Carolina Mountains, maybe even get some white water rafting in ;)

I expect to have a working version of our CineLInk capture software when I get back!

Will post lots of stuff when I get back on Sunday

have fun !
keep it real!

I will be Mountain Biking in the North Carolina Mountains, maybe even get some white water rafting in ;)


I'm jealous :-P

Does anyone know where to get an adapter to let me use a Canon EF-mount (EOS) lens on my C-mount camera? I can find tons of other adapters, but I haven't run across one of these yet.

Not sure if this will work Rob, but at B&H photo you can get a c-mount to t-mount adapter, and then a t-mount adapter for EOS lenses. So again, theoretically that should work, although I'm not sure if it will screw-up the back-focus because of so many adapters.

What's the difference between the 3300 and the 3170 Silicon Imaging Cameras?

Is it price?

Is there a reason why the SI-3170-U is not appropriate for this sort of application. It would seem to be ideal. What is the price of that unit??

Also, for Ben, do you have a raw bayer grab from the Sumix camera available?

Raavin

Jason: please check the silicon imaging site yourself to see the
difference between the camera's. Steve has enough work to
keep up with all of this as it is, and it's easy to look up the specs
yourself. Thank you.

Having said that check out his post on the 3170 (http://www.dvinfo.net/conf/showthread.php?s=&postid=205823#post205823):I wouldn't suggest it for studio work with the Altasens coming out

Jason: please check the silicon imaging site yourself to see the
difference between the camera's. Steve has enough work to
keep up with all of this as it is, and it's easy to look up the specs
yourself. Thank you.

Yes, I probably should have been a bit more clear. I suppose what I meant was, are there hidden negatives, not described in the specs, which make the 3170's negatives greater than the 3300. From reading the specs I just couldn't understand why it wasn't the most obvious choice for this kind of work.

All I could think of was price. Also there seemed to be a bit more flexibility as the 3170 comes in USB2 and Camera Link versions where the 3300 doesn't (as far as I can tell from the site).

I will try to be a bit more clear. I'm not lazy at doing research it's just that not all the information is there (plus I'm new to the deep technical aspects so it's hard to translate some of the specs to actual use ie rolling vs global shutters etc.).

I was looking more for an opinion really. Something that can't normally be reflected in specs alone. Oh and of course the price.

Cheers anyway,

Raavin ;)

There's more than price.

The 3170 is a couple years old, and has a lot of thermal and fixed pattern noise. To try and suppress that you're going to waste a lot of those 12-bits in an attempt to maximize the signal-to-noise ratio and reduce noise. The new 3300 will get you only 10-bits, but those are going to be much cleaner 10-bits that you can actually utilize.

I'm impressed the thread hasn't grown that much this time, with the new camera floating around and all ;).

Wayne,

I think there's something you're overlooking in this whole situation when you're thinking of pitching this idea to a big company.

Money spent on marketing


Jason, you are missing the point we are discussing, which is good press coverage for helping us a little (unless we go back to talking about product support in Apple products). Super Bowl, local baseball, charities etc etc etc. Sometimes they get zilch out of it, some giving to charities even done in secret (called good will), and charities and trust funds for arts, science etc, give for community/sectors benefit. So the principle is out there, and businesses (especially those plush with money) do get involved. But, what I am talking about is much more practically beneficial to business. They would spend very little helping us and in return the press releases and official websites, say they are the sponsors making it happen, which is a big return for their reputation. Big companies have the resources to get on the news wires and get good news coverage, and a news release is as good as an advertisement of the same size (that is marketing themselves). Forget marketing, forget setting up production lines, we are using unique software to use already existing products together for a new purpose. This would benefit SI and all companies (Irony, SBS was just advertising that their coverage of the Olympic Games was brought to me by Microsoft (they even paid for that one ;). We are not just doing this for the benefit of our own personal cameras but it has a greater more symbolic significance that is a benefit to the video/indie community.

With big company $$$'s comes big company bureaucracy, big company ideas, much of them the antithesis of what we're trying to do here.

Why do you think Linux is doing so well as an underground movement, finally catching the attention of the big boys (IBM)? This stuff that we're doing is grassroots stuff, not big company consumerism.

Please, have a think of how much money big business pumps into Linux (not to mention how much the distributors of Linux versions pump efforts to standardise it, that come from the profit from those non free distro's). The underground works on lots of small bit's (some of them funded under the same model I am proposing), but over all the complexity is great, and in need of authorities, or businesses, to jell it all together. I have said this for years, and it is increasingly dawning on more and more people now. I design my own OS, and I know that a horse designed by a committee is a camel, not a thoroughbred, some big companies know this, and that is why they are trying to genetically engineer the camel into a horse (or OX ;). I know that it is a very tall order. But a committee is not even a committee without structure, and any complex endeavour needs leadership (at least we have the Linux founder). But for us, we have a simple/straight forward package that can be broken up into simple sections that can be done by one, or a few people each working on a subsection. We would ask for help to finance the effort (very cheap, I doubt Rob wants 100K a year programmers wages to do it) maybe some simple driver or codec support in their products. Past this, I am not saying publicly. Sure they could offer to program it for us, but even then it would have to be open source and in line with our mission. I'm sure it's been done before, in Linux, and we don't have to bend to big company corruptions.

I am all for radical new ways to do things better, like having the whole Linux community working out each bit to one coherent and comprehensive model and working towards making it the best in the world. But human nature is that there are so many stubbornness, ignorance, lack of understanding, for sight and intelligence, politics, and competing interests (which even effect highly structured big businesses in top standards organisations (name deleted for legal reasons)) that this is near impossible in Linux (but now I think of it, it should be possible to make a program to organise things and gets past that). One leader starts with one person (Rob in the case of capture), and as I assume he is skilled, he should get much better results than ten unskilled people arguing. If you could see my OS design, and understand the paradigm shifts in it, Linux would look laughable. Actually this paragraph is a little off topic, I think I'll delete it latter.

Rob, this was posted earlier (that guy had a few interesting, well thought out things, in his post):

http://www.birger.com/html/ef232_home.htm

It also allows you to controll all the electronic lense funtions from your computer.

Actually I just had a skim (I have been so busy it has been sitting my browser for ages):

Interfacing to Your Camera

We offer a mechanical adapter to mount the EF232 directly to any standard C-Mount camera.. Mechanical adapters for other camera mounts can be provided as required. The EF232 adapter has a back focal length of 1.1". We can accomodate cameras with back focal lengths much greater than this, such as those employing thermoelectric coolers and/or shutters. Please contact us to discuss your specific needs.

But look at the price, yikes, are they for real. When you look at this, it should be able to be done with a few pic's, and actuators, for a tenth the price. I wonder who their target market was for a price like that?

Just looked around their site, interesting stuff, some camera electronics boards, FPGA based boards, and 68Billion colour Led display.

Toms hardware has just posted a new article on a 400GB, five platter, command qued harddrive.

http://www.tomshardware.com/storage/20040820/index.html

I've skimmed it, and they left out a bench mark, but still a curiosity.

http://www.seagate.com/content/docs/pdf/whitepaper/D2c_tech_paper_intc-stx_sata_ncq.pdf

Command line queing is a spec of SATA II, only this drive and a SG Barracuda 7200.7 have it (and only a few Intel chipsets support it).

It follows our discussion of setting up the read/write commands for optimal performance, to make sure the head doesn't have to wait for the desired sector to spin around again. Something that could even hinder a 720p bayer save. I'm not sure it would be better than writing the software to organise itself anway, but it is another consideration for the high end.

I must confess ingorance of how Manufacturers set up their multiple platters, wether all the heads opperate at the same time, or not, independently or in parralell. If they operate all at once independently, that would be interesting, as you could theorectically dedicate platters to capture, and one to the OS and program. Or if in parralell then all the slower inner sectors could be given to the OS etc, and old footage could be migrated there during pause, while new footage uses the faster outer sectors during shooting

Thanks

Wayne.

Wayne,
The heads inside of a hard drive are all connected to the same arm which is moved by a voice coil type mechanism.
A five platter hard drive would have ten heads... so you would need ten individual mechanisms for movement.
I don't know if you've seen the inside of a hard drive, but I doubt you could squeeze that many components into todays current hard drive casings.
Not that it couldn't be done... but we'll probably all be using solid state hard drives long before they would try something like that.

Back!

the trip was great!

Jason just for you I will post a pic or 2 of the riding around Brevard NC ;) ;)

i am waiting to hear from my programmer on the progress of CineLink while I was gone..I hope it was good! will keep everyone posted!

Thanks for the info Matthew. I imagine somebody might have done it on a high end model, but that is all I wanted to know.

But Wayne, seeing your really advanced skills and capabilities, why don't you just post some good designs and make are work easier.
I mean not your proffessional stuff, just a simple prototype.
You could help a lot making a compression routine, for example.
Thank you.

I was wondering where you got to Jaun. Put it this way, Ben and whoever else=Bayer, Rob-capture, me used to BE = cases but a couple other people want to do it now. I have suggested doing a few credible things in times past, but no interest, so no go, you can guess, you reap what you sow. As far as my research it has been much, and has ended a while ago, so be content. As far as non-professional stuff, it is all professional stuff thats the problem. I get a bone and I don't let go till I got the best possible solution (though I admit, compression using 3D shape analysis is beyond me (maybe if I use Voxels)). It's called getting it and sticking it to the rest of the world. Finance is the avenue, so I got to pull a simple one to make the money for it, and I have just bought a stack of books to get back into games programming, and maybe generate some gravy. So I advise leaving me alone for now, I got a lot to do, and only am half way through the 35mm adaptor threads. Thats why I am into just answering questions at the moment.

I actually was discussing enclosures with somebody, but that person disappeared, and before I go to somebody else I would prefer to see what they are doing. Takes time, which I don't have so latter this year.

BTW I have the case under control...as I have said we will be doing the desing in-house in CAD

Juan?

News on the Altasense Steve N?

Fellows, please, let's keep everything cool and friendly around here. This is such a unique forum, just look at all the huge threads going on. There's an incredible amount of interest here and everything would go so much more smoothly if we keep it civil and professional. Please try to keep that in mind -- and no finger pointing please, it doesn't matter who started what, all that matters is that we all work together and get along as respectful and courteous people. Many thanks to all,

I agree..will do ;)

I got a really ANGRY email from Wayne ;(

Chris please send me my post about Wayne that you deleted off the list. I have someone here that wants to read it after seeing what Wayne sent me in an email today

Hey Obin, how much do you think it'll cost to machine a case?

As of right now I'm estimating around $1,500 with mill time costing from $50-$70/hr. ($70 is for a 5-axis mill).

I can do the Solidworks modeling myself (my brother :)

I am not sure Jason..I will be doing a model in LightWave soon ..I just got an email from my programmer..says he has a beta for me to test later today! can't wait ;) I will let you know how it goes and send a screenshot

BTW Obin,

are you planning any way to adjust the gains on the camera, i.e. the analog gains? How precisely can you set them (individual gains), and also how precisiely can you set the frame-rate?

my roommate works in a machine shop. he built us a steadycam arm out of aluminum for free. maybe we could help?

yes R G B gain and RGB MASTER GAIN and framerate from 1 60fps ( or whatever your hard disk can fly)

We will have white balance of the R G B analog gains so that we get as much color info as we can in the 10bit file

Eric

what type of machines does your roommate have access to?
We would need a med-large machine to cut a case that would house all the electronics..I was going with molds but hey if you have access CNC is da bomb!

Hey guys, i'm actually in the process of building a CNC mill for what its worth. I don't want to promise anything cause its not done yet but I would certainly be willing to put in whatever work I can. Oh yeah I have'nt forgotten about making the matte box either just had to post-pone it for awhile hopefully i will be fully on track in about 3 weeks.

they have a cnc machine. if you could send me some specs of what you were thinking of building, i could ask him if its possible.

OK, this time I take a short vacation and there is a civilized amount of reading. I'll be gone for another two days.

Obin:
Thanks for answering some of my product questions.

Obin on Altasens:
We have our first color camera running. I haven't checked them but my boss is busy messing with it. Here is an example:

http://www.siliconimaging.com/Samples/SI1920/1920%20test%2016bit%20linear%20color%20corrected.zip

Altasens is being slow in releasing parts - probably no cameras until late October. We will have the boards ready, housings ready and support from frame grabber companies lined up.

Wayne:
That EOS controller is very cool - I've been looking for them. A motorized zoom is about $2K and up for c mount. For less you can use the Canon lenses. Great selection of optics. And putting a shutter on it. I'll talk to engineering about putting an RS-232 port on our cameras for lens control. Thanks.

On the SI-3170:
We had a few cinematographers messing with it about 1.5 years ago but as ....someone.... said, with the new cameras out, it isn't worth it. It is now nice for the people who need 3.2Mpix at 30fps but doesn't compare with the 3300 and 1920 for HD.

Machining:
This is also very cool - we have progressed to building cameras here. If people want, I would be happy to set up a web page to completed projects using our cameras.

TTFN,
Steve

Steve how much better color saturation would you say the Altasense has over the 3300? could you do a side by side test for me/us to see?

Hey Obin,

From what I've seen of the Altasens, it's far beyond the 3300 in ability. Saturation is not the only indication of quality, you can saturate something as much as you want if you have the right software. What does make a difference is the amount of noise and bit-dept; that's what limits saturation and other color-correction processes.

Frankly, from my experience the Altasens equals or surpasses the Thomson Viper in noise levels and dynamic range.

Of course it would be nice if I had a better RAW/bayer converter, such as something using Variable Number of Gradients, or maybe the one David Newman was working on, etc. Right now the converter I'm using, while quite functional, has a lot of problems when there's the slightest bit of noise, producing gridding patterns, etc. and I usually have to add a gaussian blur filter to remove that artifacting, and then re-sharpen the image afterwards.

But for real, the amount you can push this chips is quite astounding. And it pretty much will achive it's theoretical limit of 10 f-stops (1000:1) with the amount of noise that I'm used to seeing in a digital still camera like the D60 at around ISO500 (that would be ISO400 plus another 1/3rd stop). Or again, the amount of noise in the Viper, F900, etc. when trying to go for the maximum dynamic range (they're all around the same amount of noise, and to get the maximum dynamic range you have to underexpose them all a little, so again, it's around the same amount of noise or a bit less). Very good noise levels, color, and good dynamic range. I don't think you're going to get that out of the 10-bits on the 3300. In order to do that, you're going to have to set the white chip on the Macbeth to a setting of 25 RGB (out of 255 being maximum white), and at 10-bits, you simply can't do that without some severe banding when you normalize that, taking the bottom 10% of the image and stretching it out to the top 80%-90% and compressing the rest into overwhites. The clean 12-bits on the Altasens can do that, and I've been very impressed with this capability.

But whatever the case, as of right now, to get the quality we want out of these chips, we need a top-quality, big-screen capable bayer-converter; or maybe somebody has one and isn't telling us ;-)

Obin,

You got any screen shots of your capture app yet? Also is yours just a capture app, or a convert app also, and if so, what bayer de-mosaic algorithm are you using?

Hey Steve, should we be worried about initial quantities of the Altasens camera when you guys actually release it? Have you been excepting orders or do you not anticipate a problem? I can't wait to actually get my hands dirty on this project but unfortunatly I don't have the money to buy a 3300 just for experimentation.

Altasens:
I don't see any real problems with the Altasens availability....once they start shipping. The problem is the turnaround time for silicon. They solve their problems, simulate, change masks, queue up for the foundary (no one actually makes their own chips anymore) cut and test the dies, package and test. This is an 8-16 week cycle. Once they have parts packaged, there shouldn't be an issue (I hope, since we have a bunch of orders on the books).

Obin:
I'm not sure at the raw data level what better saturation means. Better response curves on the Bayer color filters? The two sensors are from different companies so there is a good chance their filtering is different. Better IR cut filters? I believe Altasens suggested some and we would go with their suggestions. Slow pixel response (slow analog path) smearing one color into another? I think that both are OK with this but it is easy to tell with pure R, G, B targets. To be fair, you are comparing cameras that were meant for different markets (even at the sensor level) and a 2X price difference. If Altasens knows what they are doing, and they seem to, it will be a much better camera for those who can afford it.

Ethernet:
I just finished some more instruction on the ethernet interface and was given a benchmark on the SI-3300RGB. It was running 1920x1080@24fps, 10 bits (packed as 12) over a gigabit interface, continuous with 24fps *color* data display. Pitiful algorithm but you would record in raw mode. This is about 600Mbps. This is not cheaper than the camera link solutions but I would toss it out there for you integrators.

Jason:
Thanks for the work on the SI-1920 - no one flip out - he doesn't have one - but has been testing some sample images for noise and dynamic range for us.

Hey Steve,

Thanks for all the info. Also a lot of thanks to Ari Dresler who was willing to put up with my frequent requests for images at many different setting, etc. when I meant for him to poke around with registers on a "not-so-easy-to-use" interface.

And yah, it does seem like Altasens knows what they're doing, there aren't many motion picture sensors (practically none actually, except for the Viper/Cinealta, probably the new Panvision and prototype Arriflex) out there that can take a signal where the white chip is recorded at 25 linear (out of 255, or 10 IRE on a scale of 0 to 100 before gamma correction), and then get a wonderful, practically noise-free image (again probably equivalent to a pro-digital camera like the D60, 10D, D70, etc. at ISO500) with good color saturation. 9-10 stop range no problem. Quite amazing, and very exciting for us.

So we have passed the worst now...all this time our mother board has been the big hold-up! the pci bus has a problem and has been causing us weeks of run around and crap..I got a new board and I am running the 3300RGB at full 12bit 1080x1920 30fps!! not on disk yet but soon!

man it takes a pissload of light for this 3300 camera! I am not sure we could even use a mini35 type adaptor with this chip...how will the Altasense be?

Obin, you shouldn't be trying to expose the white chip (on a Macbeth chart) for 90% white, that's too bright. If you expose the white chip for 50% white, or maybe 40%, you should get more "sensitivity".

what is a "white chip" Jason?

The 90% white chip on the Macbeth. At the bottom of the Macbeth chart there are six grey-scale chips. The 90% white chip is of course the "white" looking one on the left-hand side.

Of course if you expose the 90% chip at 40-50%, you're technically underexposing, but that's what the internal camera electonics are typically doing anyways to create the headroom needed for soft overexposure clipping and extreme highlight handling in professional video cameras (i.e., those "film-gamma" settings that are advertised with certain HD cameras like the Varicam). I'm figuring that the 3300 shouldn't have too much noise so you can safely underexpose at those levels and then normalize/color-correct in post.

Jason please call it White Patch to avoid confusions. ;)

Also if someone is interested about discovering what is the exact exposure for a given light situation and have a Macbeth chart , here you got the corresponding RGB 8 bit values for every patch on the chart:

http://www.brucelindbloom.com/index.html?ColorCheckerRGB.html

So, if your exposure is right you should get the more or less same values after conversion to 8 bit with a gamma correction of 2.2 on a PC..

For informative purposes I will tell you that value for Black Patch is around 50 and for White around 241....
This doesn't mean that your blackest black will be 50, remember the Chart is a piece of paper and it reflects some light.If you put a piece of black velvet you will get a deeper black..

can someone give me a link to a chart that I could print out and shoot? something that will show dynamic range from the 3300rgb?

all from 3300RGB Silicon Imaging Camera..I am happy with the images..I think it takes very good images and with the plus of having no smear and 1080P this is a good unit..I hope to Have CInelink Working with it soon at 24fps!

all captures above are with Xcap and the very BAD bayer filter it has ;)

it does take lots of light ...this chip/camera will need to be "lit" like film...this is a good thing right? keep the production value high! ;)

FYI the Epix capture card does NOT work with the Asus P4P 800 boards! even though the board is running the INtel 865PE chipset ..I don't know why but I have wasted weeks with this crap and I would hate anyone else to do the same!

Now I have a Gigabyte board with SIS chipset and it runs fine ..never FIFO overflow even at the max 1080p 60mhz clock!

Steve what is the MAX clock this 3300rgb can run at? 85mhz? 75mhz? I need to get CIneLInk running at that max clock all the time to reduce rolling shutter ;)

Hey Obin,

Why do you need to run at the Maximum Hz, when all you need is 48fps and dropping every other frame to get the same motion characteristics as a film camera with a 180 degree shutter? If you run the chip too high, you're not going to get the longer 1/48th of a second shutter you need, and your images will look really choppy, like "Saving Private Ryan" or something like that. Realistically, there shouldn't be any rolling sutter artifacts when you're running the chip at whatever Hz is needed for 48fps. I believe for the Altasens that we'll need to run the chip a 58Hz for that 48fps threshold.

because you can run at whatever fps you want with a high mhz..that is how we do it.

put the mhz at 60-80 for ALL shooting and do what you need with the shutter speed and or fps

Obin,
Could you give me the uncorrected 16 bit version of the outside image?
I mean the color image linear (not gamma corrected)....

www.dv3productions.com/test_images/1080p/16bit 1080.tif
