@@d00dEEE The image on the sensor(or film) is upside down (and mirrored) so the normal top to bottom shutter movement means the bottom of the image is captured first.
It... IS 1080p, if only due to a technicality, because people still measure resolutions at "full HD" and below by only the vertical dimension (an obsolete holdover from analog systems). 1440x1080 was used in some camcorder formats in the early HD era (I think normally in an anamorphic mode that was scaled up to 1920x1080 for display).
aye; 1440x1080 is 1080p, at least vertically, and I think Alec from Technology Connections/Connextras has shown early HD 4:3 1080p footage from media sourced from Japan in the past.
Another solution is a stacked sensor which is popular in high end mirrorless cams. It is a huge deal for wildlife photography because it allows for silent photography without rolling shutter issues.
There are actually not alot of global shutter 'hollywood' camera's (like Arri's new Alexa35) but the readout speed of the image have become very very fast to creep closer to true global shutter or celluloid film.
You are right. There are barely any high end camera companies making cinema cameras with a global shutter. RED recently came out with the Komodo which was purpose made to be a specialty/crash. But other than that. I can't think of anyone still offering a global shutter. Fun fact: Sony was the last company to feature a mechanical global shutter which could be synced with a second camera for 3D work in their F65 camera.
In terms of cameras, I used to be a professional photographer, so all the Pi Camera stuff is right up my alley! But a lot of it is just research, and spending a lot of time Googling, reading data sheets, and tinkering!
@@JeffGeerling I'm honestly impressed and fascinated by how much knowledge you have you make difficult situations sound simple with simple solutions, I'm an aspiring homelaber and tbh sometimes it feels impossible to ever know everything
This one is big for computer vision. $50 global shutter camera? Shut up and take my money. No 1080p? That's fine. You can hardly process all those pixels real-time and get a reasonable frame rate unless you have a beefy machine anyway.
For a hobby project I don't think the price is impressive. Virtually any old CCD camera will be global shutter. IMO it makes more sense if you need a duplicatable setup; you're unlikely to get many of the same model CCD camera on the used market.
That resolution actually sounds good to me, and with no rolling shutter, I'm definitely thinking of some projects. I do have a Pi3 sitting in the corner.

Already using HQ cam for recording laser imagery, which also has what's called a 'banding' problem, due to harmonic waveform frequencies. So, a great amount of time is consumed in optimizing the laser images with fps to minimize its appearance. The Global Shutter version looks like a great alternative solution. Thanks for sharing, Jeff. I'll have 2 please. 😎
Most professional cinema cameras are actually rolling shutter, they just have a very fast readout time (4-8ms.) This actually emulates motion picture film, which uses a spinning mirror shutter and is also a “rolling” shutter. Very few specialty cameras, like the Komodo shown, are global shutter, and they’re usually for stunt purposes
AFAIK, most Hollywood camera setups sidestep rolling shutter by having an extremely fast data bus. They still technically read 1 pixel at a time, but they do it so fast it is very hard to get a rolling shutter effect. The faster you can read off the sensor data, the less the rolling shutter.
Jeff... um... I think you missed Devin's points about the video. He was geeking out how early 19th century engineers solved two problems back in the era of crude mechanical devices: How to ensure each part of the frame received the same exposure time as the rest and how to precisely calibrate shutter speed. He was never complaining about rolling shutter or the effect it can create on moving objects. He talked about how rolling shutter solved the problem of even exposure over the entire frame of film by having two shutters with a uniform gap travel across the frame. The second was how engineers figured out how to use the bending created by rolling shutter cameras capturing a moving image to set the shutter speed timing. It's actually quite ingenious. If you take a drum with evenly spaced slits in it and put a lightbulb inside, spin the drum at a set speed, and then take pictures of the drum, you can use the pattern it makes to see if the shutters are moving too fast or slow. At no point did he bemoan the effect. It was, "look at this cool effect and what it can be used for". Now, can Rolling Shutter be a problem for some people and/or industries? Sure. Are there other solutions that avoid the pitfalls of Rolling Shutter? Sure. Could you have titled your video differently to really reflect this? ABSOLUTELY! ALSO, why did you do Destin dirty by not including a link to his video on the topic? If you're going to use his work to get more views on your channel, at least give him the curtesy of a link your followers can use to see his work.
@@JeffGeerling Okay, I found it, but only because the legend next to it seemed out of place. It doesn't look like a link to a video. (Maybe it's a UA-cam thing for the link part.)

Hey Jeff, How is it when taking videos? I have saw in some youtube videos people taking still photo's and sometimes in some light looks really good but in others looks weak for color and brightness. I'm curious about the video part.
As a photographer and videographer Rolling Shutter is literally the most annoying and limiting factor on a camera that REALLY limits some of the things you want to do. Want to use high shutter speeds and sync with a flash? You're gonna need to pay extra for a flash that can intelligently work around the rolling shutter issue to do that. Want to sync the flash to high shutter speeds and do it wireless? You are gonna have to pay extra for the transmitters that do that. Want to 3d motion track a scene and composite 3d objects in there? Don't move the camera too fast or you will need to correct the rolling shutter using software which will degrade the quality of the shot and then you can track and composite your 3d footage. I have literally been waiting for manufacturers to solve this issue since 2004 when I first started photography and it is frustratingly annoying how camera companies seem to be too dumb to solve it or worse... to lazy to because 99% of camera users don't really know what it is or care about it. This video gives me hope that some day we will have a decent digital camera that isn't frustrating the hell out of me because I want to push the shutter speed or move the camera fast
Flash sync for photography is quite the pickle; I haven't owned a camera that can sync better than 1/200 for years, and that does limit what you can do, especially outdoors with sunlight!
Probably not dumb or lazy, but because of physical limit. Because all DSLRs and mirrorless have a mechanical shutter that is like a curtain. Even if the sensor is global shutter, the mechanical shutter will need time to open and close it, and of course there will be latency when the camera sends signal to the flash and the flash actuated. Of course now we have electronic shutter that is like taking video, but the latency will still be there, and in some cases it performs worse compared to a mechanical shutter. I believe most of the consumers didn't really care that much about using flash and rolling shutter since most of them care more about resolution, color, high bitrate and high dynamic range.
should be possible to process the image to get rid of the rolling shutter effect? wouldn’t it be possible to adjust each line in software if we knew how much the camera was moved?
until next time. more pixels , same price... so we wait? havent even actual use last mega hd whateva. and think not have even cables for rpi5..so. kinda stupid change connectors. and if camera is 1080p then its good enough. phantom menace was filmed new new last high tech format 1080p LOL so its good....wait 1440...so we wait 1920
You can limit the jello effect with extremely fast sensor readout on rolling shutter-I'm guessing they can do that on those cameras to reduce the jiggle.
The result is, u cant stop blending the parameter chaos dosent react on changes at frame time. An desaster, if the light shine and then do it dark, and then bright again, the camere need 5 seconds to find the autoshutter position, but no one want an autoshutter. There is adjusted by user fix , and not dynamical. The Trigger version dosen't work in trigger case. No param accepted. HW Shutter Cam The pain in the ass strts with LibCamera
Arducam also have had globalshutter cams for a while - also low res. Hoping it will be possible to increase the resolution of this soon - great for observing moving objects in industrial applications
I'd love to see this camera on one of those cheap-ass brushed drones that vibrate so much as to completely jellify the output of their own cameras. Hypercheap drone + global shutter might be the solution to have cheap airborne cameras that actually shoot passable video, at long last.
My business partner Stan is installing these in 16mm telecine 24fps projectors. The image looks sharp, however we are still getting a lot of ghosting in scenes with lots of motion. Take a look at this clip freeze the frames with the horse jumping and running. ua-cam.com/video/HLC1Y3M7rYc/v-deo.htmlsi=WsPcQD5XnbVfK2R7
Are CCDs even available any more? Significantly older technology compared to CMOS but because they're basically a light-sensitive shift register used in a store-and-suck mode, therefore no rolling shutter at all, modern advances should have made them really good. Time to go down a Wikipedia rabbit-hole!
None of this matters until there are NO outrageously priced Pis and we can buy one when we want it. A whole new camera model but no increase in Pi production‽ Seems like drug dealers run companies better that execs with degrees.
Without a hardware *flash sync* signal this is useless for much of machine vision or scientific photography. Nothing in the documentation mentions it. Is it there or not?
Now this thing would be interesting to use on the CinePi Project. With some proper lenses attached, maybe a softening filter and a nice LOG scan of the sensor image, this would really have the potential for some nice results at affordable costs. Just wish there was a 25p or 24p version with some quality gain. I don't need 50p or 60p for a movie project.
There's also a possibility for a pseudo global shutter, which can be made by lowering the framerate or shutter speed instead of resolution. It's the same rolling shutter, but the row values are read only from the part of the exposure period where all rows are exposed. There is an overlap between the time interval for the bottom row's frame 1 exposure begin and the top row's frame 2 exposure begin. So it'll be like, if the normal row period is 10 ms, all rows will be exposed for 20 ms, and only the last 10 ms of the first row and first 10 ms of the las row will be considered for illumination. All those exposure values will be in the same period.
At first, I was very excited when I saw the pricing. However, for the application that I have in mind, it is useless without a hardware trigger. I think they are missing out big time by not introducing this feature.
How about this, use 2 HQ cameras very close to each other, and flip one of them upside down. This way one cam will record top to bottom and the other will record "bottom to top" because of flipping it. Then correct it in post, that way you have an almost perfect non-rolling shutter solution. Has this been done before? If not someone should do it.
Hello there @Consig1iere ! That is a neat idea, but I think you'd get rolling shutter in both directions. So in one video the Top Left of the image is read first, and in the other recording, the Bottom Right would be read first. But in both videos, the opposite corner is read last. Then if they were combined carefully, I think you'd end up with kind of a V-shaped distortion so that the center seemed to lag behind the top and bottom of the object. There is software already for removing the rolling shutter, but I think there is a bit of a crop as it slides the lines over and ends up with a straight image, with slanted edges to cut off.
@@I4getTings Yes, I saw a presentation that showed how UA-cam developed an automatic rolling shutter compensation system, and it did involve some cropping
Does anyone know if hardware binning to lower resolutions is possible with this camera?! Pi V2 cam can do hardware binning to 32x32 pixels, if I'm not mistaken. I would like to buy this camera if binning is possible to small resolutions for easier training. Considering this is a camera built specifically for AI, it's probably possible?!?
I don't see the benefit that would have with a global shutter camera. Wouldn't software downscaling before the AI training work just as well? I'm sure there's a way to do that with Linux even if your app doesn't support it natively.
@@eDoc2020 Yes, under normal conditions, I would train network at 128x128px and use software resize. But, software photo resizing on weak hardware takes "a lot" of resources, and hardware binning is free! I want to try to prepare AI for super weak hardware, like Raspberry Pi (without MIPS chips, etc.) or Esp32. I want to see how much I can get out of the miniature resolution, eg hand gestures and similar, on 32x32px (and possibly higher framerate) I have no idea on details yet, I just know want to try it! :) Hand gestures are sometimes super fast, so a global shutter would come in handy. It's amazing how much AI can extract from a small resolution, where we humans see almost nothing, especially if you are working on software for your own use, in your apartment, and if you are not going to change environments - then the network somewhat overfits on the background of your flat, and that part does not change, so training is faster and generalization seams better.

Without a hardware *flash sync* signal this is useless for much of machine vision or scientific photography. Nothing in the documentation mentions it. Is it there or not?
It's absolutely 1080p, just not widescreen.
Another pi accessory, just in time for me not to be able to buy a pi thanks to continued scalping. 😢
Is this camera good for capturing sky activity likes stars, meteor shower etc?
Now they should fix their supply issue. It’s 2023 not 2020.
I have a question which camera is best for computer Vision projects
This is why i still prefer CCD sensors over CMOS sensors.
Who will you be next time?
Always a good question!
is this a better option for RTSP setup for face recognition as compared to norma raspberry pi camera?
There's two kinds of people: those who believe this is pointless, and those who know how grand this is.
Now this thing would be interesting to use on the CinePi Project. With some proper lenses attached, maybe a softening filter and a nice LOG scan of the sensor image, this would really have the potential for some nice results at affordable costs. Just wish there was a 25p or 24p version with some quality gain. I don't need 50p or 60p for a movie project.
just wondering why we never heard you play guitar in a full song
what is the default resolution does this camera takes
Please can you try the Mixtile Blade 3 as server cluster?
so, not a fix, just information on alternative part 🤷
That's cool, but I wish there was also a higher resolution option for more money. I'm not spending $5k on a fancy camera, but I would spend like
Is it possible to run Windows 11 on rock 5b sbc ?
can't see rolling shutter bending because of tearing on my Arch system
oh those FOSS problems
Heh, that's a slightly different problem. But in some ways more annoying!
now to find a new raspberry pi to use it with
There's also a possibility for a pseudo global shutter, which can be made by lowering the framerate or shutter speed instead of resolution. It's the same rolling shutter, but the row values are read only from the part of the exposure period where all rows are exposed.
There is an overlap between the time interval for the bottom row's frame 1 exposure begin and the top row's frame 2 exposure begin. So it'll be like, if the normal row period is 10 ms, all rows will be exposed for 20 ms, and only the last 10 ms of the first row and first 10 ms of the las row will be considered for illumination. All those exposure values will be in the same period.
At first, I was very excited when I saw the pricing. However, for the application that I have in mind, it is useless without a hardware trigger. I think they are missing out big time by not introducing this feature.
Neato!
you didn't open the cover nooo
Damn what a great video
I thought you had managed to fix the shutter problem using two cameras somehow, didn't think it was a new camera release.
How about this, use 2 HQ cameras very close to each other, and flip one of them upside down. This way one cam will record top to bottom and the other will record "bottom to top" because of flipping it. Then correct it in post, that way you have an almost perfect non-rolling shutter solution. Has this been done before? If not someone should do it.
Hello there @Consig1iere ! That is a neat idea, but I think you'd get rolling shutter in both directions. So in one video the Top Left of the image is read first, and in the other recording, the Bottom Right would be read first. But in both videos, the opposite corner is read last. Then if they were combined carefully, I think you'd end up with kind of a V-shaped distortion so that the center seemed to lag behind the top and bottom of the object. There is software already for removing the rolling shutter, but I think there is a bit of a crop as it slides the lines over and ends up with a straight image, with slanted edges to cut off.
@@I4getTings Yes, I saw a presentation that showed how UA-cam developed an automatic rolling shutter compensation system, and it did involve some cropping
@Cyberguy42 ooh, cool! I'll go looking for a video on that
Does anyone know if hardware binning to lower resolutions is possible with this camera?! Pi V2 cam can do hardware binning to 32x32 pixels, if I'm not mistaken.
I would like to buy this camera if binning is possible to small resolutions for easier training.
Considering this is a camera built specifically for AI, it's probably possible?!?
I don't see the benefit that would have with a global shutter camera. Wouldn't software downscaling before the AI training work just as well? I'm sure there's a way to do that with Linux even if your app doesn't support it natively.
@@eDoc2020 Yes, under normal conditions, I would train network at 128x128px and use software resize. But, software photo resizing on weak hardware takes "a lot" of resources, and hardware binning is free!
I want to try to prepare AI for super weak hardware, like Raspberry Pi (without MIPS chips, etc.) or Esp32. I want to see how much I can get out of the miniature resolution, eg hand gestures and similar, on 32x32px (and possibly higher framerate)
I have no idea on details yet, I just know want to try it! :)
Hand gestures are sometimes super fast, so a global shutter would come in handy.
It's amazing how much AI can extract from a small resolution, where we humans see almost nothing, especially if you are working on software for your own use, in your apartment, and if you are not going to change environments - then the network somewhat overfits on the background of your flat, and that part does not change, so training is faster and generalization seams better.
1.6 megapixel? What is this? 2006?
Watch the video again, and repeat until understood.
@@phillee2814 wow. What a smart one. Missing the point while telling someone they are missing the point. Your parents must be proud
@@sobertillnoon Lol did your parents drop you on your head when you were a baby...lol the irony.
@@backgammonbacon I literally made a stupid joke. A guy missed the point. And then you rode to his defense because why? What does any of this accomplish?
@@sobertillnoon AAH yes - the "only joking/can't take a joke" defence. The last refuge of the idiot.
Now if we could only BUY the Pi.....
Someday... 😞
Hey Jeff, was the hq camera also updated with the release of pi camera v3?
no
Is the shutter speed dependant on the camera module? With this having a global shutter I'd be interested in building a camera with it.
You must use the Sony Alpha 7 S 3.
a6600 is the camera I use, but it's very much like the A7SIII
Woke up in the middle of the night and couldn't get back to sleep, and Jeff still had me covered. Patreon sub is totally worth it.
nice content!
The RED Komodo is a Global Shutter cinema camera as well, for applications with need for a larger sensor
Makes no sense, you can fix smart, but not fix stupid?
Global Shutter baby!
Glad to have you back Jeff. Hope you are doing well!
dno what you did, just seemed like another ad to me
Great Job 👍
Good to see U R feeling better! Thanks for keeping up the work!
whats the use case for such camera?
machine vision, tracking fast subjects
Another exciting camera tech, is event driven sensors!
show some projects using libcamera please
Another Jeff upload ❤
Wow he should see this
It would be amazing if Destin could do a follow-up on digital cameras and global shutters!
Many of the Phantom high-speed camera models have 'GS' and it does make a big difference in some cases.
@@JeffGeerling makes me wonder if this is the reason why GoPro cameras have a huge mark up or it’s just marketing gimmick
@@s0rr0wHacker GoPros use rolling shutter. Even the ones that would benefit hugely from global shutter, like the max.
I wonder if that is another RaspberryPi Product, that nobody can buy....
The camera hardware seems to be in abundant supply, at least. Just hard to find a Pi to go with it.
Looks very useful. Great video!
