<strong>TOKYO, August 31, 2016</strong>—Canon Inc. today announced that it has developed a new CMOS sensor equipped with a global shutter function that, because it exposes all of the sensor’s pixels at the same time, enables the capture of distortion-free images even when shooting fast-moving objects. Employing a new signal-readout drive system and new pixel structure that significantly expands the full well capacity and reduces noise, the sensor contributes to high-image-quality video capture by making possible the realization of a wide dynamic range.</p>
<p><strong>Distortion-free image capture when shooting fast-moving objects

</strong>Standard CMOS sensors make use of the rolling shutter method, which sequentially exposes the pixels one row at a time. Because rolling shutters can create slight discrepancies in signal-readout timing depending on the location of the pixel, images of fast-moving objects may appear distorted and flash photography may result in the occurrence of the flash band phenomenon, in which the upper and lower portions of images display different levels of brightness. Because Canon’s newly developed CMOS sensor employs a global shutter; when shooting such fast-moving objects as a rotating propeller or a speeding train, subjects are able to retain their proper form to create distortion-free images. Enabling the confirmation of object shapes with a high degree of accuracy, the sensor offers potential benefits in industrial applications, including as a sensor for use in inspection cameras.</p>

<p><strong>Wide dynamic range realized through new proprietary drive method and pixel structure

</strong>When the newly developed CMOS sensor converts light into electrical signals and stores the signal charge in memory, the new drive system achieves a significant expansion in full well capacity. Also, because it employs a structure that efficiently captures light and each pixel incorporates an optimized internal configuration, the sensor makes possible increased sensitivity with reduced noise. The expanded full well capacity, realized through the sensor’s new drive system, and substantial reduction in noise, enabled by the new pixel structure, combine to deliver a wide dynamic range, facilitating the capture of high-image-quality, high-definition footage even when shooting scenes containing large variances in brightness.</p>
<p>Canon will explore various industrial and measurement applications for the newly developed CMOS sensor and consider deploying it in the field of video production for cinema production applications, TV dramas, commercials and more.</p>

Eh.... This smells like C700 level technology for now. Seems curious they would announce this just days before the rumored unveiling of the new "Arri-killer"

I think it will eventually trickle down to, say, the new C100 III? XC-15 I kinda doubt for now. Whether the sensor is 1 inch (XC-15) or Super 35 (C Line) is mostly irrelevant. The readout is going to be the same if the pixel count is the same and they are all in the 8.3 to 8.8MP range.

I think maybe we eventually get this in the next gen DSLR series in a couple years. But apart from cray high Sync speeds There's not a whole lot of additional benefit on a stills cam. Rolling shutter is only really problematic when you're shooting video. I can't ever recall an instance where I took a still and thought "Oh damn, if ONLY I had a global shutter!" lol

My reading of the announcement is that there is no mention of sensor size *OR* how many megapixels.

If you get right down to it, I too could develop a 1 pixel global shutter digital camera :)

Maybe even 2 ;)

The point here being that Canon has CMOS sensors in many pieces of equipment ... and given the leaked images, maybe this feature will debut in the XC15.

Vice versa. This will be a revolution in flash photography.

It is basically the holy grail of flash photography.

Imagine sports photography over 20 to 30 meters distance with flash!

Using rocket devices like the Hensel Expert 250 D Speed, you can even do this at 4 fps!

10 meters (30ft) distance will give you up to 8 fps!

Would this allow true higher x-sync speeds, and not that HSS junk?
With a true global shutter, all pixels get exposed at exactly the same time so x-sync speed would be as fast as the sensor can be driven (240Hz?)

With a global shutter there is no x-sync speed, you're limited only by flash duration.

And it will allow still frame grabs of fast-moving subjects without the rolling shutter effect. But sure, nothing to do with photography. ::)

Now, just because it would be a benefit to still photographers, it doesn't follow that Canon will provide that benefit any time soon.

Yup. Jimmy Olsen's gonna want one of these!

I'm fairly flash-naive so please pardon this potentially stupid question, but couldn't this also help with flash recycle time? Given that the flash doesn't need to fire for as long to ensure all of the pixels get even illumination at the same shutter speed - the flash duration could be shorter... right? Or... no?
The longer the flash duration, the more total light is put out, so a trade off between captured light and fast shutter speed.

Let's be fair to AWR. Read his whole quote.

Oh C'mon funny people.
This is Cinema stuff. And industrial other high end.
You won't see this on your DSLR or XCtoycams, maybe never.
Even the most expensive DSLR:s don't have much of the Cinemaline goodies.
Nothing to do with photography. Big problem in cinemacameras.

Clearly, he meant it has nothing to do with still photography because it's not going to be coming to your DSLR anytime soon. The press release from Canon makes that pretty clear. This is about cinema and specialized industry applications.

So, for those getting all excited about high speed sync and other still photo applications, don't hold your breath.
