I think the reason that we're "stuck" with one sensor is that among these industrial camera manufacturers, the Altasens is the only chip that was designed from the ground up as a professional HD camera chip, and is being incorporated in many high-priced professional HD camera systems, including those from Ikegami, JVC, and Kinetta.
|
its also the reason its so expensive :(
|
Something I couldn't find - or maybe I overlooked it, what lens mount can we expect to find on the 2/3" industrial camera's with the Altasense chip?
Although I guess that when you put together a system with that particular sensor, you'd be able to budget for an adapter to PL mount or ARRI Mount... Bar3nd |
I have been sick. sorry for not talking much..
I am now starting to think about going with 8bit because of the issues with display rate and datarate with 10-12bit files and the problems with editing ...I do have a new version of CineLInk that is working much better but I have not had time to test as I was sick ;( ..in the next few days expect some updates ! I have a problem..I need a board that has AGP on it because the onboard video from the ITX and micro boards WILL NOT WORK..I used one. it sucked bad. ideas / links gang? |
Altasens question!!!!!!!!!
When is this Altasens 3560 CMOS do to be released?
Is the Altasens ProCamHD 2560 released or is it going to come out when the 3560 is released. Looking at the specs at both Altasens chips chips below....... If one was to stick with 720P, wouldn't the ProCamHD 2560 be just fine? Also 2560 is at a lower cost I would think too? ---------------------------------------- ProCamHD 3560 - 2/3", 1936 x 1086 pixel high speed, low noise and low power iSoC for high definition TV cameras ProCamHD 2560 - 1/2", 1280 x 1024 pixel with ProCamHD's performance advantages PLUS interoperability between HDTV, analog TV (NTSC/PAL) and SXGA resolution. |
Obin, what board did you use?
Those 855GME boards are using AGP, it's just using an on-board chip. Why all the problems when a Pentium M at 2.0Ghz is a very fast chip? This all seems very confusing. Finally, what API are you using for display? OpenGL, DirectX, directly to the framebuffer? |
some directx and some framebuffer
board I used was a fullsized atx board with built in video display like the micro boards have..it sucked BAD very poor performance... |
Can you give me processor and chipset specs? That would help out a lot since there are so many ATX boards out there.
|
What are the prices on the Altasens chips? I can't seem to find that in the mass of posts.
Also, why are the altasens chips considered to be so great? Do we have any tests? What is the signal to noise ratio and dynamic range? |
Obin Olson what camera did you capture these with images with.
Obin, I just figured out it's your footage that we had put on a movie theater screen here in OC,ca. When I got the clips I never knew who posted them etc. Now I do. Your clips looked amazing on a 30 to 40ft screen considering the were just samples. Test Shots from Obin Olson: http://dv3productions.com/test_images/test1.jpg http://dv3productions.com/test_images/test2.jpg http://dv3productions.com/test_images/test3.jpg http://dv3productions.com/test_images/test4.jpg http://dv3productions.com/test_images/test5.jpg http://dv3productions.com/test_images/test6.jpg |
I'm not sure about the chips themselves, but for the cameras based on these chips, expect to pay around $4-6K.
|
What did you show them on? a Projector? 35mm film?
does it look as good as the Panasonic VariCam on the big screen? please tell!! |
Hey Obin,
You wouldn't mind telling us what the integrated chipset you were using was, would you? I know you're saying the small boards are no good, but I'm really curious to know what the specs on the board you were using was, as I would like to avoid it too. There are too many integrated chipsets out there to simply say that "such and such is always bad". Knowing the processors and chipset would be a huge help in finding out just what is needed performance-wise for these devices. Thanks. |
well it did say SIS on it ..not sure what chipset I will look and see if I can find a box
BTW the 3300 has MUCH better colors then the IBIS5 chip ...wait till we get this thing going ;) Looks like CIneLink is working now..maybe..so far testing tonight is good..good framerates and it looks like we are saving on 2 disk drives 10bit raw files..I have trouble opening the raw files..working on that now... |
best way to convert raw files?
Obin:
How is the best way for convert the footage .raw that you have posted? Thanks |
I would put a .DNG header on them. Then you can demosaic them in photoshop.
|
of course, how is everybody doing their RAW files, little endian or big endian?
the TIFF spec says that any bit depth that's not 8 or 16-bit has to be big-endian for the way the bits are packed. The file itself can be little endian, but the image bits must be big endian. If that's the case, then simply putting a .DNG header on a RAW file isn't going to do much good. |
Wayne,
Thanks for the reply regarding the audio. I think that this issue should go on a different thread, as some working cameras are pretty much out there. Speaking about A/D converters I found a standalone converter box (look at ST/SB ADC/Digital IN/OUT although th DI2000 has higher end features) that can be part of the modular camera concept. |
Jason: Rob S. and myself are using Motorola order for the IHD
files. So that would be little or big (I get confused on those things)? |
I guess little is Motorola and Big is IBM.

I am sorry but i have not understand! Can you tell me the softwere for see that raw file posted by Obin? (i have understand photoshop for the second step,but for the first step?) Best regards |
some wild ideas
first of all: GUI Why ?
hold on http://www.handykey.com/ the old one twidler 1. I've worked for years. I've been on the wearhead group from Steve Man for years. It is araound very cheap. There is even a smaller one I lost the name. They are called chord keys. you have to train a bit but they do everything a decend keyboard plus mouse can do it works with Windows and Linux. Dreaming a LCD attached to the camarabody and Steve Nordauser application running there Eeen more strange and back to the roots as Vance is anywhere member of this board a mechanical shutter. we are free to have a camera with the best Chip the fastest readout and free from any shutter problem. As we are not Arri nor Kreines back to the roots using a 16 or whatever camerabody optical Viewfinder, voila we want to see what the lens it giving us... anyway and the deja posted SBC with a SATA array or an array of firewire diskdrives Kreines uses the ipod disk'sit is not so far away ronald real time programmer, no Gui only hexcode, freelance Camaraman, 3d nerd |

New Sensors:
Steve and others:
I too think it is a real shame that the Micron 1.3Mpixel didn't work out because of the smear etc, the images did look nice otherwise. Steve is there any really cheap sensor on the horizon that can produce pictures like these without the problems? I have been researching the Samsung sensors and Smal sensors, but because of the protracted sickness, other commitments and the trip I'm about to go on I haven't got sepcific specs/details enough to decide. But I might as well tell all, the cheap still camera sensors they have included a kit with lossless compression engine, USB2.0, and memory card (not that that helps). Even though the public specs say different, when you put together the data rate etc, the sensors should be able to do 720p, but the sensors maybe programmed not to do that as they are meant for cheap still cameras (under $100 and up). They have a pixel resetting scheme (like dual slope) for very wide range. I can't remember if there was a global shutter, but maybe. I posted links to some pictures on the technical thread a while back. I don't know for cinema, but definitely something for cheap value HD video/doco. So as you can see they would be a better option than the IBIS5 or Micron 1.3MP. Don't flame me just have a look at the smal site (dev kits). If any engineering person would like to look into it developing it, just send me a post on the technical thread so I can email you. |
Re: some wild ideas
<<<-- Originally posted by Ronald Biese :real time programmer, no Gui only hexcode, freelance Camaraman, 3d nerd -->>>
;) pity not too many people can see the use of that than C not the use of it ;) Do you use menuetos? http://www.menuetos.org/ (Statement: have never used menuetos, and have never read it's doc's, as I am developing my own, but know of it's existence). |
Wayne: I'm disappointed you can't read hex codes (in realtime).
Would make for such an artfull display <g> |
Rob, don't be dissapionted, if they can read Matrix code
in the movies, surely you can read hex codes ;) |
Samsung
Wayne, I went to their website and banged around the sensors a bit. The largest 1.3MPix is still only 1/3" If you do that, you might as well take a known clean sensor like the Micron 3.2Mpix (no smearing, 1/2") and window it down to 720p. We have that now - Obin is working with it. The Micron 1.3Mpix advantage is the larger pixel size (more sensitive, shallower DOF).

....please!!
help me to understand the best way to convert and see the .raw clip posted by Obin. <<<-- Originally posted by Jason Rodriguez : I would put a .DNG header on them. Then you can demosaic them in photoshop. -->>> I am sorry but i have not understand! Can you tell me the softwere for see that raw file posted by Obin? (i have understand photoshop for the second step,but for the first step?) Best regards Gabriele |
Obin, you had mentioned going back down to 8-bit because 12-bit was causing too many headaches. Are you still thinking about doing that, or are you going to go ahead with the Altasens chip at 12-bit. Is the 3300 of a high enough quality to shoot a good picture with?
|
have you guys consider this cmos: http://www.foveon.com/prod_f7.html
foveon 10.2 mp that at 25 fs I think it will work at 1080 but not shure, rolling shutter.and 1 inch would be yust great. thanks |
Dear Marto
since 2000 I'm on the route to HD no kidding that's the best forum here. My backgroung is realtime analysis, picture analysis in Automation astro physics and for living and DOD, stooped all 2003 look down the page for this beauty of chip 25p they do with a resolution rediculus low like all the Kodak etc in photo apparatus. I do guess it's pure politics to protect Dalsa Sony Viper and all imaging reall DOF real HD for the Indi....film only Signma is using this chip people on the street reading 3.4 MB pixel rubbish !! they don't understand these technic at all they don't read 3.4 MB x 3 for RGB that's not bad at all that's no bayer at all that's quite a bit like real film works fantastic Why take a NikoCanoMio etc 8Mb Bayer that means nothing at all so Sigma is telling the truth and the rest is not lying at all that's the problem it's only waiting for the next chip, waiting waiting and time passes by waiting for next year an open real recorder was working for 40 years and now? DAT oh no Minidisc oh no A Nagra was running with less power than most laptops oh yes in astro/physicc they do it use multiple chip's Imaging to use 4 Faveon RGB is all on one chip no focal problem no need to de- bayer AND a mechanical shutter there are A/D and all already for each quart of resuoution out there we have to use something like a master clock to sync the whole system pump it out to a backpack of I'Pod disks good old viefinder chep optics from 35 mm Signa optics are chep and not bad at all so we can use 35 optics some years old pure mechanic maybe do nothing at all pump it in...a PC, Linux. Apple orwhat else change the array mechanical like the next film roll Camarawork is not lunatic a small SUV ist most time only some passes away I'm gorilla cameraman, after that electronic nuts,that's my order doing the best picture why not ronald |
Meos or menuetos
Dear Wayne that was a good one well I've heard about lost the
direction a bit was engaged with Linux but happy to see it again I do guess all what I do need is to write data to an disk array nothing else shutter mechanic, as Vance told us lenses mechanic keep it simple first only sync the whole and change the arryay to a fresh one dektop graphics machine in a SUV, Van, Volkswagen-bus sbaop the array in Cinarella on Linux is not bad free and HD ready !! even Hollywood knows abaout Film Gimp free not bad at all some others else so what ? |
foveon going wild......
God day again: http://new.dpnow.com/1160.html
please scroll down and look what they call porros viewfinder amazing no penta-prism anymore so what about ? multiple chips with an mirror setup cutting the incoming image in quarts. a bit overlap maybe could all scroped and even geometry treated by a simple batch procedure on the host PC where the disk array snapps in mechanical shutter you know my personal fetish Thank you Vance !! pump it on disks why not maybe I got wild but tell me what's so wrong with it The beauty with Faeon no bayer artifacts or If you like take 4 Micron and do this look get the "biggest Pixel" best light with 4 CCD good low light.... it's only an idea mirrors cutting down the image in 4 quarts have nothing found beside astro-physics and so on |
Ronald! Snap out of it!
Please don't put every single word on a new line. Stay away from the return key! (MODERATOR NOTE: Ronalds posts where edited for better readability, so Barend's comments above no longer apply) Apart from that - I'm trying to make sense out of your posts... Lining up the chips on the prism so you can use 4 chips to make one picture is a pretty tough job. If you plan on resizing and perspective correcting the different outputs from the 3 chips to line up you'll lose resolution right there - by resampling the image. Sounds like a lot of hassle for a limited gain. In theory it could be done, but to be honest, if I see what people can push out of an IBIS chip, i feel a single Altasense would return great pictures with a lot less hassle. To make these DIY camera's work, they need to be technically straightforward. Preferrably without groundglasses or prisms. A prism for the viewfinder would be an idea, although a videou output on the camera would be great also. Bar3nd |
Hm first if you don't like my writing ok I'm cameraman, graphics
artist and realtime nerd. I do like to write in short lines Times does it it's easy to read on any monitor. I've not talked of any prism at all Mirros thats easy, cheap and ?? nothing has to be done in the camara. only pump it on a disk array with 35mm nothing was done in the camera that was ok Why to have a replay. As I told you Film is not lunatic a Van Motorhome is never far away. There a batch procedure is run stiching the pichtures and so on 15 minutes or 8 that's ok keep the camera simple that's film Light is coming trough the lens an optical Viewfinder will show all you can put any lens on Kreins thinks a bit so going on Ibis5A the factory was sold october going on Altasens ok but next year the chip will change and so every year well the pictures it does are pritty good did not thought it's only an Ibis5a Altasens thread maybe posted a zillion times who knows about: http://www.panavisionsvi.com/imagers_Quad.htm from the page The sensor integrates all timing and signal buffering on chip. Video is output via 8 analog outputs each with programmable gain and offset. p.s. ok will do but if not at home I've to read on my palm-top and so it'smore easy, imagine to read the NY TIMES with no columns just do this. Is crolling down the screen so painfull only to know about? ronald |
Ronald:
http://www.machinevisiononline.org/p...ls.cfm?id=1056 Originally developed by Photon Vision Systems. Got an early design-in with the JVC camera. Last time I checked, the entry into a design with this sensor was extremely high, sensor costs were very high ($30K)??. Of course, I haven't looked in a year or more. Very sweet - you can do quadlets and still have HD so it is more like a 3 sensor camera. |
Dear Steve, merci.
I'm subriber of the online version, but sometimes, SMPTE, Millimeter,Braodcast news and so on igoes to the !! bin and sit's there. An old one: http://www.urbanfox.tv/articles/came...9joedunton.htm The pic is showing Obin's idea, an Arri S16 and the back attached. You know best a decend HD viewfinder is out of price range, an LCD nice, if there is sun only pain. go there http://www.kinetta.com/home.php Ok Kreines is what Ballhaus is for me, sorry me born Berlin, grew up elsewere 11 times moved due to dad's profession, he is a real hardcore cameraman. For this cam lenses you can find on the market, pl mount Angenieux is out there as well as S16 sometimes very cheap, it's not prime Digi Zeiss but ... i'll still think only to write picture son disk, Kreines uses the I-Pod disks, Toshiba 2.5", 1.8" are there. 20 Minutes or 30 not more an small array will do. All processing could be done, some meters, as I wrote- film is not on the dark side of the moon, and if it is not top secret, set, a Van is only some meters away, like live recording. There the arry snaps in, the pictures are copied on SCSI or SATA arrays ond voila you do need at least two I-pod array's no rocket sience, sorry. Next one, on http://www.joedunton.co.uk/ a bit strange the page click on "news archive" and then on may 03 look here (pdf format) drink a cup of tea and read on it's mainly Ikegami stuff 2 CCD . Why a S16 Camera Body the ergonomics a cameraman is used to, the baseplate, the Kompendium anything is there. I thing of a DIY Steadycam rig, there a decent TFT monitor would make sense it's a bit cyborg like but walkable as a 35 mm with an staedycam rig is usual but no easy job at all. ronald p.s. I'm sitting in a coffe shop writing an a tiny display, I do hope you can read and there are not only typo's |
going wild again
G'day, hi all my edmond optics catalog tells me on page 56 about a Rhomboid Prism doing nothing else as displacing an image or the input beam. Ok A stack of two right hand and left to it a stack of two inverted would give us 1/4 image displaced from the optical center just out of the focal plan. That could be the low budged quad sensor.
Crazy,-- we would have native 35m format, native 35 DOf. With a russian 35 mm camara body..cool, the indie viper. Maybe here somebody is crazy enough to think off. It's not cheap at all,but cheaper as any HDcam in the 35mm format, well it's bayer coded, but,with a decend optic could be fantastic. Mechanical shutter, I'm still Vance devoted, a master clock and anyway coded, write it on the so called 2.5" Toshiba disk array. Think of a typical set, not a lunatic one, there is a car, a break, somthing near. There the arry goes, and in let's say some minutes the images are stiched together and can be shown. thats light fast compared to real S16 or 35mm processing. ronald |
