The RED Komodo 6K rumour mill is starting to get some confirmations as it gets closer to production. RED President, Jarred Land, now has a “Stormtrooper” Komodo 6K in his hands, the white colour typically denoting a pre-production unit, and has let loose a few more specs, including the fact that it uses a global shutter sensor.
Published in the Japan Journal of Applied Physics, Canons is working on a new global shutter CMOS sensor with dual in-pixel charge domain memory. The rather technical paper explains the research and development of the new sensor technology.
This new technology would allow camera manufacturers (or, at least Canon) to remove the final major mechanical component from camera bodies. With a global electronic shutter, there is no need for a physical mechanical shutter anymore.
Rumours of a new “Mini A9” APS-C Sony camera seem to be popping up more and more as we get closer to Photokina. But a new announcement today may offer some insight into what may be announced in a couple of weeks.
Sony has today announced a new 31MP APS-C sized CMOS sensor with a global shutter. 31MP is slightly larger than 6K, and while 6K isn’t unheard of, it’s possible that the new Sony IMX342LQA isn’t destined for a video camera, but a stills camera.
A spec sheet has been leaked to the folks at Sony Alpha Rumors about a new Sony sensor. Of course, new sensors are released all the time, so what’s so special about this one? Well, it’s a 31MP resolution APS-C sensor with a global shutter that potentially offers 4K video at up to 108 frames per second though SLVS-EC – although much lower is more likely.
Well, it seems that Sony isn’t the only one with a global shutter CMOS announcement of late. According to a press release, Panasonic has also just announced a new global shutter CMOS sensor. This one, though, is capable of shooting up to 60 frames per second at 8K (36MP) resolution. Unlike Sony, which utilises a rear illuminated design with parallel DA converter, Panasonic’s uses an organic photoconductive film (OPF) to allow simultaneous readout of all the pixels on each frame.
Rolling shutter has been the bane of DSLR and mirrorless video shooters since the beginning. In fact, for users of just about any camera with a CMOS sensor. This is all down to how CMOS sensors traditionally work, scanning the scene line by line. Each line is captured at a slightly different point in time, so as you pan, it appears that subjects are leaning or wobbling. Hence it’s become affectionately known as the “jello effect”.
That may be all set to change, though, thanks to a new breakthrough from Sony who has developed an entirely new CMOS sensor with a global shutter function. Announced last week at the International Solid-State Circuits Conference (ISSCC) in San Fracisco, the new sensor features a pixel-parallel analogue to digital converter. This means that it can read the data from all of the pixels simultaneously.
Canon have announced that they’ve developed a new CMOS sensor with a global shutter and expanded dynamic range. While a wider dynamic range is always good for every camera use, the global shutter is huge for video shooters. Finally, we’ll be able to completely eliminate “jello wobble“, skew and other rolling shutter artifacts in DSLR video.
The fundamental difference between a traditional rolling shutter CMOS sensor and this new global shutter is the way it records the scene. Rolling shutter sensors capture a line one line at a time, sequentially. This means that, now matter how small, the beginning and end of your exposure happen at different points in time. A global shutter records what every single pixel sees at the exact same time.
Sony, is not waiting to see who will win the sensor wars, it is defining the battlefield. With rumors of new technologies being around for a while now, Sony recently released two videos showing what’s in store for their future line of sensor technology.
Specifically, Sony demoed Starvis – an ultra low light technology designed for security cameras, though with the current low light / high ISO specs battle, it would not be surprising to find traces of this technology in their consumer line as well.
According to Sony :
Sensors are not as trivial a film. At least for me the simplicity of chemistry was always simpler than the magic of electronics.
Vimeo user Raymond Siri created two quick, yet informative animations for Canon that illustrate how CCD and CMOS sensors work.
The movies show how the light is filtered accumulated and then they show the difference in how the data is sent for storage.
