Anyone else catch the 2 in the binary numbers at 1:53 ?
yes
It wouldn't be binary then. It would be ternary.
***** yes
Didn't even need to see it to believe it. I knew LMG would do something like that as soon as I saw all the 1's and 0's.
indeed, fail
CUDA CORES vs STREAM PROCESSORS PLEASE
Same thing, just different words.
"Cuda cores" is a term used by Nvidia. "Stream processors" is a term used by AMD
Wawaweewa Rice You still didn't explain what they are or what they do. You just talked about the naming.
***** he said vs. not what are they
JustaTree If you are going to compare two things you need to know what they are first. You can't compare apples and oranges if you don't know whats an apple and whats an orange.
***** Well a youtube comment is really no place to discuss what they do. Someone interested in what they do can google it and get more information than what someone could give in a youtube comment
This was a nice rap song!
LMAO!
What? My name is. What? My name is. What? My names is... LINUS
i realize Im quite randomly asking but do anyone know of a good site to watch new movies online ?
@Mekhi Gary Flixportal
@Reyansh Holden Thanks, I signed up and it seems to work :D Appreciate it !!
this guy's voice is sometimes hard to listen to, but this is just the video I needed to watch, answered all my questions
Linus lost me at 0:15 , after that i just zoned out and realized it was 4 in the morning
it's 5 in the morning now..
Jerkface155 and im still awake...
Same lol
Jerkface155 what is wrong with us
Nothing
1:37 "in your br%@#in"
gale HAHAHAHAHAHAHA
Linus! A Topic for you!
Can you PLEASE make a comparison once and for all about what the big differences are between DLP and LCD Projectors!? I am really stuck as to which type of projector has the least amount of input lag as possible (for gaming of course). Can you please settle this?
Thank you so much for your consideration.
Nigga I'm leaving here even more confused about image sensors.
Linus isn't a "nigga". Go back to World Star HipHop, and making Vines.
Garrett Bradley Kinda racist Not all black people are on World Star hip hop or vine
Garrett Bradley
You must be disconnected from the world if you think black people are the only people using "nigga" lol.
Itaku I NEVER SAID THEY WERE BLACK
"Nigga" mean some who a black person
Yes I totally and completely understood everything in this video because I'm so smart... *cough*
yo watch out. if that cough gets worse you might want to go to a doctor. but you're so smart u probly dont need me to tell you
You need cough drops?
...cough...cough
Shit its contageous
Ebola

I just got into film, amazing process, especially learning to develop it yourself! And you get a physical copy of all of your pictures, which you can reprint infinitely!
Was that whole video done in one take? BREATHE LINUS
Film cameras are really nice, I recommend everybody use them sometime. It teaches you to not be lazy with your photography and also gives you much more respect for pretty much everything to do with pictures. You can also mix your own solutions for hella cheap so it just takes more time than digital nowadays.
The "hella cheap" part sure didnt age well
CCD sensors have lower digital noise when given enough light but they are terrible in low light. CMOS sensors are kind of the opposite however the technology for CMOS is improving too.
Thank you for explaining it concisely
I got so much to learn from you... You're great keep it up
Beautifully made video, love it
This again, makes me wonder how efficient and effective our eye's mechanism of capturing and processing images when comparing to the current technology (May/2020).
and it's quite funny that we're praising analog video/audio when our nervous system is technically digital.
Great episode, thanks!
Excellent explanation.
1:53
Anyone notice the 2 in the bottom right?
hax0r
Great video guys - loved the indepth view and graphics for the CCD v CMOS comparisons. This was definitely a FAP with brains! ...Which is hot.
*nods*, *nods*
So they work through magic.. Got it!
fantastic exactly what i was looking for
its funny that i was serching for"zfs as fast as possible" instead of google it....i like you guyz how you explain points..and mostly how you connect sponsered ad..😃😃
Loved it thanks Linus
Dude thanks for saving me in my assignment, I owe you
The voice cracking at the start of this video makes me love it all the more
NTFS VS FAT32
PLEEEEEEEEEEEEEEEEEEEEEEEEEEASE
YES PLEASE!
Fat32 is older and supports 4GB files max. NTFS is for windows, but supports files bigger than 4GB
How about popular file systems in general?
or general file systems like hfs+ NTFS EXFAT and FAT32 and FAT(16)
+Hassan Qandil NTFS vs EXT4 vs Btrfs vs ZFS vs the one made by a murderer?
I've heard from some a few years ago that the extreme enthusiasts only use film because of it's pure nature. I wonder how true that is or will be as the digital photo process get's so much better than it was.
always cool to learn something new and add to the bucket of geeky knowledges.
Nerd
Jonnathan R thanks for the complement.
Well, he just predicted computational photography a few tears early! Fun!
I knew it! "Intel Inside" just meant they wanted to get into my brain!
wait... that tune was catchy... so they already are!
Thanks for clearing that up :)
Linus... as much as I love you (being the 14th that you published it), I have to disagree: CCD technology USED to have lower noise at specifics ISOs, specially lower ones. Which for most professional photography types, is needed most. But things have changed in the last 8 years. CMOS sensors have reached the same level of noise at low ISOs, while retaining greater IQ in the high ISOs, as they have better signal amplifiers, and specially since the convertion to digital has fewer steps, and therefore, less electronic noise is created. Anyway, almost all camera manufacturers have switched by now to CMOS, instead of CCD. Perhaps there are a couple medium format sensors out there that are CCD, but don't expect them to be many.
I remember when i was young and my parents use to keep the camera films in the fridge XD
3:28 i was wearing hea'phones and I thought I was being hit by a freakin car
Thanks for the video, do you have a similar video about CSI 1,2 and 3 sensors?
i have canon 1100d , while capturing pictures, picture is not clear and has lots of noise.. will changing new sensor make my photo quality better??
Awesome a Quickie lol! Thanks enjoyed it.
Which image sensor is best for phone and why
Sony vs samsung vs cmos....
What a great video!
those subtle background noises that are intended to mimic 'computing sounds' drive me crazy
I think the reaosn why people are so confused about this one is that he didn't really take the tie to explain the OLD system of how images are captured.
With film photography, the lens of your camera leads light into the rectangular hole right in front of the film when the shutter opens. The film is made of a special material consisting of crystals sensitive to light on a transparent piece of plastic. It's literally a piece of transparent tape lined with crystal.
When the film is developed, parts of the film that receive more light become black, and parts that recieved no light basically fall of the tape, leaving transparent film. This is why developed film is "negative", or reversed color.
A DIGITAL IMAGE SENSOR attempts to work the same way as how the crystals on traditional film are CHEMICALLY ALTERED when exposed to light.
Think of the sensor as that film that lies behind that rectangular hole in a film camera, but in a much smaller size, and instead of "crystals" that get exposed to light at a microscopic scale, you have little teeeny tiny squares, one for EVERY PIXEL, that are each recording data for the amount of exposure to light, and the color of that light, among other information (color has temperature and tint as well as exposure, there are lots of variables).
So instead of developing a piece of FILM to remove MICROSCOPIC CRYSTALS to give a perfect image, a sensor is reciving pixel-to-pixel information, and a computer chip is processing the value of every one of those pixels.
Clear explanation
this video explained all I need to know in a humorous way!
Thanks!
best explanation of how it works thanks , awaiting iphone 12 max
So every picture we take is actually a little technological marvel
Not one of his best videos. Quality has improved significantly over the years.
On a similar topic I think you should cover RAW image capture and its benefits/drawbacks compared to using the camera's processing to create JPEGs
jpegs are compressed image. RAW has the best quality.
I know the difference, I think it would just be helpful and interesting to many others
I must admit I haven't read any of his articles. I am interested on what this 'bullshit' is that you are calling him out for?
MrTitskie His site is probably the most visited photography website on the internet, he reviews everything. And with that much traffic he tells people that JPEG is better than RAW despite RAW being better in every way and by far, he tells people to shoot in auto mode, or P mode, which he actually believes stands for "professional", and a whole bunch of other stupid shit, he's basically just a dad with a camera that got lucky with traffic and now he's capable of spreading stupidity and terrible advice to millions.
oBLACKIECHANoo maybe you should go back and read his reviews a little more thoroughly...
do a fast as posible about all the different image types please
Oh good heaven's, I had forgotten about geocities.
Good explanation, Linus. Was hoping for a shout-out to us microscope users when you said "specialized uses for CCD sensors" but oh well.
there's also something called neocities thats works as a replacement, also if you look up achiveteam they have partly archived geocities before it went kill
3:59 I was disappointed to not hear the rest of the Intel jingle...
What's a 20mp sensor for when 4k is 8.3mp? Thank you
Could you explain the difference between the Bayer/Foveonx3 filters?
A question about the sensor.
Which one is better and offers the better image quality?
1/2.5" Progressive Scan CMOS
1/2" Progressive Scan CMOS
1/1.8" Progressive Scan CMOS
3 years later, but it's the 1/1.8" one. The bigger the sensor, the better (1÷1.8 is bigger than 1÷2.5)
So for mobile phones, are CCD or CMOS used? Because i bought a cheap phone and it says it has a CMOS sensor and i dont know if thats a good thing for a phone or not.
CMOS, all of them. But the tech says nothing about all other parameters that matter way more.
Why is there more green on digital? And why was blue more common on film/analog? Curious to know since I'm into Sci-Fi (use of blue screens and green screens)
Woow wow woow this is an in depth review ....
Thumb's up
why cmos have lower noise in slr camera
This video misleads all the point. The CCD sensor are historically less expensive to produce than the CMOS (Read any digital photography book). The CCD sensor needs less power than the CMOS due to the sensor layers: CCD reads light through a RGB Bayer Colour Filter (25%R + 25%G + 50%B) that is why you will find them on phone cameras, compact cameras or in the first digital cameras. While the CMOS has 4 sensor layers to each one of the RGB Colour (100%R + 100%G + 100%B) and you will prefer to have them on DSLRs cameras due to fullframe, more colour space with bigger processors and RAW formats. :)
Great explanation! The question that I have is on the comparison of ccd vs cmos. You had mentioned that ccd is better in low light over cmos. The issue I have with this comparison is that in most digital cameras (i.e. a Leica M using CCD and a Nikon DSLR using cmos) the ccd cameras have moved over to cmos sensors in consumer/commercial applications due to cmos having better low light capability by the way of increasing the sensors sensitivity know as ISO. In a CCD sensor this sensitivity increase "cap" is typically much lower before you start to product unwanted noise in the resulting image. This is why Leica cameras (even though very expensive yet product great images) have a much lower ISO rating than most entry level/consumer DSLR cameras of today that use Cmos. Were you referring to the CCD sensors having better noise handling at lower sensitivity (ISO) ratings compared to a CMOS sensor, at the same ISO? Im just curious on this. Thanks!
Correction... I meant to say Leica m9 and under. The new Leica M uses a cmos sensor now.
Do CCDs have a “rolling shutter” problem?
love the faze logo on your shirt man
Watched video before posting. Very interesting technology actually.
have you just seen the 2 in the binary code ?
So square space is a website builder? Can you keep the page you made after your trial has expired? Like export it to HTML and CSS or do they want you to pay monthly to keep your design?
Greetings.
Could you help me to get the IMX179 datasheet?
from what site does he get al his pictures?
What is the difference between UTP and FTP cable?
you're awesome linus
Should you put annotations over the "get started" box of the squarespace ad? It's kind of misleading us a bit thinking that "get started" box is clickable when it's not...

Laser stoped and live mode interruptted Sensor 4979
May I know the reason of showing these?
give our brains a run for their money *Intel jingle* 😂😂😂
haha, he done the opening bit to it, and I just instinctively went "dun dun dun dun" in my brain 😂
It was my understanding CCD pixels operate on principles making them closer to photodiodes, gathering electrons and holes, while CMOS image sensor pixels operate by way of the same principle as xerox machines and laser printers, id est the fact photons reduce the static charge of a charged substrate when absorbed by it. I think the charged substrate for CMOS sensors would be capacitors.
A friend of my fathers that use to work at Micron once spoke of the way people noticed dynamic ram chips without their packaging could act like primitive image sensors if you just read the memory addresses before filling all their digits with ones again. Was never very practical because of the spare addresses they print on the dies to replace dead addresses, plus the arrangement of the individual addresses, and the devices making them up, does not lend itself geometrically to putting the image together after getting the values.
I also once found an electronics enthusiasts magazine from somewhere in the eighties with an article in it discussing whether ccd or dynamic ram was going to become the dominant RAM technology. Thought that was interesting...
1:48 - Can you spot the Futurama joke?
no explanation of the sensor size number and other jargons?
Smear effect on CCD Sensors?
The image sensor in my eye caught my brother and uncle kissing.
I like to guess which sponsor is being advertised as soon as Linus or Luke start the segue :D
A+ The humor alone is worth watching whether you are a techie or not...
hey man we want a modern version
Screen size & resolution (in relation with desktop ergonomics) please :(
That's weird. I upgraded my camera since the new model had a CMOS sensor, vs CCD on the old one. Low light performance has increased dramatically.
Also, the cheapest cameras on the market use a CCD sensor.
Take this for example:
www.samsung.com/us/photography/digital-cameras/EC-WB30FZBPRUS
versus a more expensive model
www.samsung.com/us/photography/digital-cameras/EK-GC110ZWAXAR
It's the same on all other cameras out there. So how come CCD is more expensive if the cheapest cameras always have CCD sensors?
1:53 bottom right corner - nuber 2 in binary code 😉😀😉
What is Cuda Cores Pls :)

How to choose right Image sensor & how image sensor works: ua-cam.com/video/FJRO77HcJ74/v-deo.html
This video will help you learn how to choose the right Image sensor and how image sensor works. You will also learn about the factors to be considered while choosing an image sensor for a specific application.
The way this video is presented it would make one think that only CCD sensors have a rolling electronic shutter and only CMOS sensors have a global electronic shutter. The reality is the opposite: most CCD sensors use global shutters and most CMOS sensors use rolling shutters. Good video though.
Please do a video on how baby lamas learn to walk when they are born
I remember the days when digital cameras were not very common and the internet was not full of photos in the same way as it is today. In those days the digital cameras that did exist were crappy and expensive. I am glad that now a decent one can be had for the same price or even less. I like how smartphones are coming with good cameras. If you ever had an Xperia or similar phone you would know exactly what I mean. I like the way prices keep falling while technology keeps getting better.
That's because they are manufactured in 3rd world countries.
Can anybody please recommend the best cameraphone running android. Thanks.
Samsung camera phones with zoom.
Why did that eye sound like the TNG Warp Core?
actually ccd should be the one with rolling shutter issues, because with ccd rows are being read out one after another, while cmos reads all rows simultaneously.
The sensor may only be exposed to light for a fraction of a second due to some sort of shutter/electronic shutter, and CMOS may be exposed the entire time it is being processed, because it can be processed faster, i.e. the CMOS sensor does not require a shutter, but the CCD needs one to operate properly, and the shutter that has been installed on the CCD just happens to be better than the CMOS.
you didn't mention the vidicon tube
What can give a better resolution classic Film or cmos Image sensor? Is it really worth it to spend an arm or a leg on a sensor when you can just scan in the film ?
depends on the scanner you use
It's difficult to say which is better when you take into account the gear you're using as everything can affect the final outcome. If we use only high quality 35mm film and ignore everything else, you could get up to 70 MP equivalent. However, a lot of that when zoomed in is noise, just like what you see when you blow up a digital picture too much. To get that better than digital photo, you'd need quality gear and a real nice film scanner, those disposable film cameras and a $150 home scanner won't come anywhere close to cutting it.
I was looking at 'High res' scanners like 600dpi+ was over 5 grand. Might as well get a 4k camera at that point.
Yeah, go for a good digital camera. I still do film myself but that's because I have access to the gear to do the developing and printing and I love it, but it's quite the hassle compared to digital.
It depends on how many pictures are you going to take and if you can handle the workflow of film (both preshoot and postshoot). Film will probably be cheaper but you must be sure of know what you are doing, you cannot be trigger happy and take lots of pics for the sake of it, and you are restricted in ISO for the loaded roll (also high ISO film is expensive and wont get as high as new digital cameras) and the obvious no preview until roll is processed...
I think digital is better for home and professional use, but if you see photography as a hobbie (as I do) it is nice to ALSO have a film camera just to use it ocasionally, not as the only camera.
When I was looking for my first DSLR I was tempted for buying a used Nikon F100 or something similar with compatibility with new lenses but I wont ever regret spending the extra money going for digital, specially if you want to learn!
LOL geocities. I havent heard that in a while now. :D
