Stacked Sensor: The Future of Camera Industry
Вставка
- Опубліковано 23 гру 2021
- Megapixel has always been a dilemma to the camera manufacturers, until the arrival of stacked sensors. As the sensor size increases, burst rates drop. So there was almost no full-frame camera with a burst speed of 30 or near. Where a stacked CMOS sensor contains multiple layers. Usually, the first layer contains the pixels, and the next layer incorporates the logic. So stacked sensor is the future of the camera industry? Let's dig out the answer.

Really nice video, educated me very well. Deserves more like and subs definitely
So excited to learn more about the upcoming Fuji XH2 with this technology. I think we should be hearing from Fuji about these quite soon. 👍 Technology constantly amazes me. There are some incredibly intelligent amazing humans out there designing and making this stuff. Just mind blowing.
I came here to understand how they work, i'm leaving as clueless.
Very educative..... Can you do video about the meaning of flagship cameras and non flagships..... Thanks 😎
I was thinking a stacked sensor was something that took 2 different sensitivities of light. Where the photons would fall onto one at a high sensitivity for capturing more detail in the blacks, and as it passed through onto the other sensor, the second one would stop blowing out the highlights. So the resulting RAW image would have a much higher dynamic range and you would never have to worry about nailing correct exposure.
Great idea, this is kind of like what Dual ISO in magic lantern does but using normal one sensor, just sampling alternate lines of same frame with different ISO's for that same reason. Gets you 2-3 stops of DR for almost free
What do you think about organic sensors?
Thanks
So, can you print big with a 20 mp stacked sensor? I'm looking at the Olympus OM 1 for landscape and selling my 5d Mark iv.
OM-1 would be a better option.
There is no real explanation in the video why a stacked sensor can be read faster.
The Canon R3 with it's stacked sensor got a firmware update that allows it to take ONE HUNDRED NINETY FIVE (195 that's right) RAW IMAGES IN ONE SECOND !!!!! It's crazy. 50 frames per .26 seconds. RAW. Dear God I love technology.
Rolling shutter has nothing to do with speed.
It is entirely possible to make a global shutter CMOS sensor.
They just have lower sensitivity and more noise vs sensors using the rolling shutter regime.
The problem is apparently caused by cross talk between electrical signals produced by individuals pixels interfering with each other and causing signal noise as a result.
The more pixels you have running at once, the worse the problem gets.
By only exposing a single line of pixels at a time the cross talk issue is eliminated, or at least largely reduced - thus the rolling shutter effect as each line of pixels on the sensor gets exposed just slightly out of sync with its neighbor, enough to foul up high speed action like propellers on air planes or helicopters and any number of other thigns.
It can be argued that a drastic shift in sensor electrical layout is needed to overcome this issue as it is holding back the tech at a fundamental level.
Much as the pigment/dye based color filter over the sensor is also bottlenecking pixel sensitivity - metasurface based filters may fix this problem in the future and give image sensors a serious low light sensitivity boost in the process.
Woah, thanks for sharing!
haha and then a9iii gets released
you forgot to point out that Nikon Z9 doesn't even have mechanical shutter. Nikon able to make this happen because of the speed of stack sensor technology.
Yes you said rite stacked cmos sensors with buffer readout is the future but with a only a handful cameras and that to high end ones like the Sony alpha 1 ,Canon R3 not even Canon r5 and recently released nikon Z9..not all cameras have them, but the upcoming cameras will have then for sure. The newly released fujifilm X h2 s is a new great camera. But in crop A -psc. nice work..👍
computatinal photography shoul be enabled in cameras to compete with mobile photography........
So why then does the Fujifilm XH2S have LESS megapixels with a stacked sensor compared to the XH2, which has higher resolution and a non-stacked sensor?
Because stacked sensor is still not that much popular, R&D cost is high too. We'll see more of the innovations in future for sure.
Some cameras manufacturers are saying fewer megapixels means each pixel can receive more light and they're just as good as slightly higher megapixel sensors. Taking what we know about stacked sensors, some camera reviewers are saying you really don't need high megapixel count because they are far superior to the equivalent single sensor design. It would nice to see someone actually testing this theory.
Or maybe, JUST RETURN CCD SENSORS! They were superior!
so long from the release of the video and still no affordable options with stacked sensor 😢
All image sensors are layered so this video is miss leading.
The underground-complexes around the world should be very interested in applying BSI-CMOS (stacks) to their micro-dust micro-electronics baking lens-coating computer jar-jar-binks starwars movie-projector oops camera-sensor directional-vector oops.
Eeee... to the power of minus 6
Coating is the etching
Lens surface... aim stacked.?
Trust the indians to rehash CCD-sensors for micro-switch without micro-lens. Habitual jumper-wire are easy scapegoats
Laser blast inside glass for "hologram" glass-block display and OLED are bulk-price tech at e‐³
Stacked cmos sensors are not the future they are now
As long as manufacturers continue to use stacked sensors more frequently.
This stacking isn't addressing Bayer colour filtering. Sigma's Foveon is the only true full colour image sensor available though it is very slow with poor ISO performance. I'm looking for 3 separately located RGB sensor technology so that each pixel has full colour sensing ability without guessing and making a fool of photographers by using clever anti aliasing processing which is a fake image no matter how many mega pixels. Join the only true camera SIGMA don't be a sheep. Sony, Panasonic, you can do better? Stop the fake AI image processing.
