Major Breakthrough: Moving Images from AXIOM Alpha Prototype

Submitted 11 years 2 months ago by Sebastian.
We have made a major development breakthrough enabling real-time Full HD video output via the AXIOM Alpha prototype’s HDMI port. (The final AXIOM camera is planned to have 3G-SDI instead of HDMI interfaces, but for now we are using what is available on the Zedboard development platform). Our current prototype allows us to output progressive 1080p video at up to 60 FPS downscaled from our 4K Super35 image sensor. This represents the completion of a major milestone on our path to the crowd-... » Read more

apertus° webserver

Submitted 11 years 2 months ago by Sebastian.
As you have probably noticed, we had a significant website downtime over the weekend with our entire web-server, including all sub-domains and services running on it, being inaccessible. Fortunately, all files were backed-up and we were able to resume operations on Monday. Many thanks to Fritz Ledl from domaintechnik.at for the quick solution and supporting us from now on with a sponsored server. Image under creative commons by U.S. Pacific Command » Read more

apertus° decides: open or closed source for AXIOM

Submitted 11 years 3 months ago by Sebastian.
What does "open" mean? There has been an ongoing community discussion around the level of openness to which apertus° will be willing/able to go with the Axiom. This discussion has lasted for several years up to now. On our website (See: “Why Open Source?” ), we have detailed the problems that openness can introduce with proprietary interfaces. In most cases, developers are forced to sign binding non-disclosure-agreements (NDA) before any technical documentation may be acquired. With this in... » Read more

apertus° heading for Berlin

Submitted 11 years 3 months ago by Sebastian.
We have been invited to showcase the Axiom Alpha prototype at the Photonics Congress in Berlin on February the 20th, 2014 . The event itself does not seem to be open to the public but if anyone in that area is interested we can surely schedule a meet up time/place while we are in Berlin (from the 19th - 21st). » Read more

Think big apertus°

Submitted 11 years 3 months ago by Sebastian.
The European Union has just launched a massive initiative to support sustainable innovation throughout the next 7 years, working with the tremendous total sum of close to 80 Billion Euros (no, that's not a typo). The goal is to enable open scientific research, leading to innovative new products that tackle the social challenges we are facing today. Can you already see where this is going and why we're posting about it here? If you've been following our twitter activity recently, you might have... » Read more

The Extended AXIOM Gamma Open Module Concept

Submitted 11 years 4 months ago by Sebastian.
The Extended Extension In our first post about the Axiom Open Module Concept (made in Fall 2013), we proposed a solution explaining how different modules could be combined behind the camera head to form a wide range of camera hardware compounds. Now we have prepared an extension to this concept, dealing with the same issue surrounding the components in front of the camera head. Here, it's not so much about allowing for new combinations but rather to allow for easy access to these parts and for... » Read more

AXIOM Gamma Camera Concept Update

Submitted 11 years 4 months ago by Sebastian.
Romance with the Big Camera Looking at this "behind the scenes" image from Romance on the High Seas , one wonders how people managed to create entire feature films whilst working under the limitations imposed by professional cinema technology in the 1940's and 1950's. Today we are used to carrying around greater processing power in our pockets than the fastest supercomputer (the Cray 1 from 1979) was capable of more than 30 years ago. Times have changed dramatically! Behind the scenes on "... » Read more

Merry Christmas from the apertus° team: First 4K RAW DNG

Submitted 11 years 4 months ago by Sebastian.
This year you can open one present early: First 4K RAW DNG image from our Axiom Alpha prototype: As we've previously stated, please keep in mind that our sensor calibration and tuning- alongside our image conversion logic development- have just begun and this image represents a camera in a very early developmental state. For example, the image has had no fixed pattern noise corrections or hot pixel compensation applied amongst other things that we just have not had the time to implement yet... » Read more

Second AXIOM Alpha Prototype Unit ready for action

Submitted 11 years 5 months ago by Sebastian.
The second Axiom Alpha prototype unit, now containing a full grade image sensor, is complete and ready for further calibration testing. Please remember that this prototype- housed in a custom enclosure made from laser cut acrylic glass and a wooden base to provide the assembly with greater strength around the tripod mounting plate- is a proof of concept, designed to test the electronics and allow us to capture images in the same manner as with a real camera, under proper lighting conditions... » Read more

Axiom Alpha原型机进展报告

Submitted 11 years 5 months ago by Sebastian.
这次向大家更新一下我们在硬件和软件方面的开发进度。首先,Axiom Alpha原型机的开发工作进行的相当顺利,并且很高兴的告诉大家,在我们的原型机上,RAW格式静态图像捕捉功能一直表现的十分出色。但是,我们还没有进行更多校准和测试,因为我们正处于原型机外壳制作的收尾阶段,再者,考虑到成本因素,我们装在原型机上的这个图像传感器,更适合为开发服务。其次,在第二代Axiom alpha原型机中,我们对它内部的组件进行了小部分的改进,并装配了全级图像传感器。接着,我们将会对第二代原型机进行更全面的测试。 上图为配备有全级图像传感器的黑色镜头卡口(第二代原型机使用) 在白炽灯下使用Axiom Alpha原型机拍摄的RAW格式IT8测试图(对坏点进行了修复) 在钨光下拍摄并进行了初级校正的IT8测试图表 你会发现,我们的白平衡预设功能也正在开发中。如果你拥有这方面的经验或技术,并且感兴趣的话,请 联系我们 的开发团队,协助我们对这部分进行改进。 下图取自HDMI输出测试: 上图可以看到HDMI信号的"重像"-所以需要对一些时序错误进行修复 修复后-上图为Axiom... » Read more
