What we need is a 1" sensor so we can get close to 24x18mm and no need for an imaging screen!

New, 4*4*8cm 1080p60 camera, and ultra thin reflected lens system

I have posted these, because they appear significant, for what can be done in the future.

I am curious what price this camera will be, and compression/data rate, as it talks of network.

The lens is very thin, it works by bouncing light around inside the lens, off of reflective surfaces, until it finds it's way to the sensor chip.

I have send them email to give us some more info about senzor they using, and about the price.
I think that lan is only for configuration, and preview, HDSDI is their main output

Have anyone seen this:

Would this work for a HD homemade camera?

That link didn't work for me. I did a search on their site and found this:

Today I have receive answer to my email.
They redirected me to this site:

Please contact.... ( I have edited this part because of personal email adress)
www.easylooksystem.com

I will ask this other person for details about this camera, and to join us on this forum.

Igor Babic February 15th, 2007 04:17 AM

Today I have receive email from easylooksystem. They are very interested to yoin us here, and i hope very soon we will find out more about their camera system.

Here it is, prices and basic info. Definetly not for home made guys. Broadcasters are probably they target market. Real live HDSDI video is what this camera gives out. No RAW. Its 18,500€.

Dennis Hingsberg February 16th, 2007 07:37 AM

Approx $50,000 USD? Is there something wrong with them? You can buy 3 red cameras for that price.

Modula HD CAM latest info
 
Last couple of days I have receive some more info about this camera:

"The MODULA HD CAM is capable of providing RAW data. The RAW data output is not implemented yet, but we are planing to provide 12 (!) bit raw data over HDSDI link and to store it in open exr (http://www.openexr.com/) file format
We are shipping the MODULA HD CAM already. Our customers right now are "early adopters" with special applications. We also got some interest from indie film makers, who are considering to substitute their S 16mm camera with the MODULA. We are trying to get all the info (details, sample clips and stills) you and and other interested parties are asking for and to put it on the new web page. The web page relaunch is scheduled to be ready for the NAB in Las Vegas."

Denis:
18.000€ is about 23.600$

Igor,

I have to ask, the www.arecontvision.com products, they sound very similar to Elphel product, do you know if they are they using Elphel open-source designs?


Thanks

Wayne.

Wayne Morellini March 16th, 2007 12:06 AM

Here is an 2000*850 frame at 85% Jpeg quality, from over at the Elphel thread:

Amazing what can be achieved with even an cheap sensor.

Igor Babic March 16th, 2007 02:04 AM

Wayne, I will ask them.

Creating new capture software
 
Hello everyone,

A couple of weeks ago I found this forum and decided to take a shot into creating a bayer field recorder software application for Mac OS X. I have already some experience in writing field recorders for audio, see:
http://www.vosgames.nl/

In any case I've looked around for cameras for around a week and it seems like the Pike 210 from Allied Vision Tech is a pretty good contender. As this is a Firewire 800 IIDC camera the maximum resolution at 24 fps and 16 bits (14 bits + 2 bit padding) is around: 1786 x 760 (2.35:1) or 1920 x 654 (2.75:1).

I have also looked at the GigE cameras, but I can not find the specification of the protocol, so I've decided to go for IIDC for now. I've bought a cheap IIDC camera, called fire-i, to start experimenting.

The plan is to let OpenGL do the heavy lifting: dead pixel repair, black image subtraction, pixel sensitivity compensation, and reordering the pixels for better compression. The plan is to lossless compress the bayer image so that it will be possible to record on a single external SATA disk.

The OpenGL pipeline will also be used for previewing: demosaic, color conversion, false color (zebra patterns on steroids), HDR rendering, zooming for focus, more stuff I can think of.

I am not there yet of course, I currently can view (using OpenGL) a grey scale live-image from my fire-i camera.

I've been going round in circles for the last week; should I pre-process the raw data or not. pre-processing would yield better compression, doing these later could potentially give more freedom to choose a different algorithm.

As I already need to process the images in real time to show the camera operator what he is looking at... You can still record unprocessed images by using the NULL calibration settings, which is also the way to capture calibration data.

Cheers,
Take
