AXIOM Alpha Prototype Progress Report
Submitted by Sebastian on Wed, 12/04/2013 - 12:25
This is a combined news update regarding both our hardware and software development progress. As you can see, our work with Axiom Alpha prototype is coming along quite nicely. We’re sure you’ll all be happy to hear that raw still image capture has been working well on our testing board for quite some time now. However as we are still finishing the prototype enclosure, we have not yet carried out many other calibrations and tests - especially considering that the image sensor we’ve installed in the only prototype built so far is (for cost purposes) a defect sample better suited for prototyping. A second Axiom Alpha prototype unit containing slightly improved internal components is now being assembled with a full grade image sensor. This second unit will allow us to start more extensive testing soon.

As you will notice, our white balance presets are still a work in progress. If you’re interested and posses the required skillset to work in this area, please contact our development team to assist with fine-tuning.
The following images have been taken from our HDMI output tests:
HDMI signal “ghosting” visible in the images - still some timing bugs to fix
After Debugging - What test images currently look like when coming out of our Axiom Alpha prototype’s HDMI port
What we’re now working on is the FPGA logic to supply the HDMI feed with real-time Full HD image data. HDMI video out from memory is already working, however we experienced a number of delays and problems with the memory interfaces, which did not behave as documented when using both interfaces to feed data into the memory from the image sensor and feed the data from the memory to the HDMI interface simultaneously.
Converted DNG in UFRAW
In parallel, we have started coding a program that converts the raw data captured from the image sensor into a DNG file. Whilst this is already working pretty well, things like additional metadata, camera profiles and hot/dead pixel definitions still need to be implemented or improved.

will you use the CMV12000
will you use the CMV12000 sensor, capable of 300pfs@4k in your final release camera?
As the new image sensor
As the new image sensor version is physically identical with the one we are currently using we are of course very interested in it.
But just replacing the sensor is the easy part. Our current sensor already creates ~1.8 Gigabytes of data per second when running at maximum resolution/speed. Double that again and you can imagine the challenge of saving this amount of data somewhere in real time :)
As long as, when all is said
As long as, when all is said and done, the finished camera can shoot 144 FPS while using the alternate exposure HDR capability mentioned on the Image Sensor page, it's good enough for me. I've some interesting ideas in mind...
:-P
Amazing work! We cant wait to
Amazing work! We cant wait to see some video samples and while we know you are far from beta testing these in focus groups, we would love to be on your list of testers eventually! Really exciting, this looks like it could be the camera for us :)

Hi have you updated github? I was thinking of buying the hard ware this week and start developing along side and share ideas. Also I noticed that the component layout for sensor board was not there. Thanks for all your hard work
We are in the process of
We are in the process of making sure all files on github are up to date, but please get in touch with us as some parts can only be ordered in bulk and we still have some spare ones.
Hi Jonathan,
Hi Jonathan,
We've just updated our repository on github: https://github.com/apertus-open-source-cinema/alpha-hardware/tree/master...
FYI, v1.1 is the one we are using, v1.2 incorporates all the changes that we've so far found useful, alongside a little more. You're welcome to join us on the apertus IRC at the following server: irc.freenode.net (Channel: #apertus)
Look interesting! Can wait to
Look interesting! Can wait to see the final products. Best of luck to you guys.
Awesome news! Keep the great
Awesome news! Keep the great work for open-sourcing the source of images. :-)
I'm loving this progress.
I'm loving this progress. Please keep the information flowing. Congratulations on your on-going milestones. If the final camera can shoot at 150 f.p.s., it will blow anything else out of the water.
Great work guys... this is
Great work guys... this is the most interesting thing going on in the whole world for me at the moment... exciting opportunity to revolutionize the Video Camera industry.... Awesome!!!
Was there any progress on looking at a built in ND filter for on the fly shooting?
I would love to develop a Sports version perhaps with the CVM2000... 1080p with heaps of fps... would be amazing!
We have not found THE
We have not found THE solution for NDs yet but we will soon present the next version of the open modules concept that could lead to an integrated ND filter system in the future.
Sweet guys... keep up the
Sweet guys... keep up the good work... Will it be possible to build in different sensors as modules too?
