How Do Scanners Work?

[@MythozTheMyth]

@2:33 im pretty sure something went wrong with the rgb lukes

[@Nitsuga-lb5br]

Green screen issue

[@AyushBakshi]

I thought the same

[@DouglasWalrath]

pink, noisy pink, and green

[@tonyrulez69]

Interestingly the Floatplane video didn't have this issue.

[@Dreathjoe]

thought i was color blind but then i saw Steam app icon at the taskbar lol

[@unfa00]

This is the best intro to a technical video. I love your videos, guys!

[@forestman111]

"Crappy phone camera" while using a Pixel lol

[@TexelGuy]

To be fair, the pixel's camera could never match the quality of a real scanner. Which is what he meant I think.

[@david_escalante]

TessellatedGuy he said crappy phone camera, that's not "what he meant" it's pretty clear what he said. Also, yes, it can match and even get a superior quality, since it is... you know... a camera.

[@AdamEspinosa]

Cameras can be much higher quality than scanners, the main issue is getting the consistent lighting that scanners are great at.

[@Hunterdietzman]

Where's the joke?

[@Vylpes]

+OverscorePlayZ Because the pixel has one of the best phone cameras and the quote contradicts that a little

[@lii4714]

2:32 Is everything ok?

[@mthompson965]

He's being held hostage by Linus.

[@trychan959]

I tought the video title is How do Scammers work

[@Lilly24244]

Same; "And suddenly your phone lights up because of a friend that needs an important document...*... for some reason..."

[@roskon1]

"crappy built in phone camera" luke says while holding pixel, which has best camera out of all smartphones. Don't you ever change Luke, Love ou

[@JohnSmith-qv3ew]

That is a Google Pixel. Phone cameras are greatly inferior to scanners though. It is next to impossible to get it flat using the bundled camera app. Apps like Microsoft's Office Lens help, but you can't beat a flatbed scanner.

[@Yek_]

Lol iPhone cameras in 2017

[@PaulHojda]

Even a Google pixel takes shit pictures in low light. There's no beating physics

[@dvdossbsvskfbdvav]

Paul Hojda well turn a light on I just beat physics.

[@binkzera2777]

Paul Hojda I don't know if you've heard of this, but most phones have a thing called a flash specifically for lighting up your images. It usually doesn't take more than a few taps in the camera application to activate it.

[@unvergebeneid]

So the difference between CCD and CIS according to the video is that one uses light and a light-sensitive sensor, while the other uses light and a light-sensitive sensor. Thanks a bunch for that explanation ;)

[@tutumannyAQUE]

What is the song at the beginning? It sounds really good!

[@redhawkrobin]

It was a cold night and I was crawling up under my sheets. Then all of a sudden it struck me: how does scanners actually work? I took my phone , Did a quick Google search and clicked the first link. Little did I know that I was watching a techquickie.... Damn these are everywhere xD

[@aunairqureshi816]

Lol

[@cyb3rspac351]

Great video! 👏 This was excactly what I wanted to know!

[@Ahmad-cj4ef]

Realistic heart touching intro

[@MatthewBester]

Tiny glimpse of Luke's glamorous home life. 😂

[@daftnord4957]

HP's AIO printer app has a cool scanner feature that uses the phone/tablets camera to take a pic, then crops and fixes the white sheet and blackens the letters, looks nice

[@lancelindlelee7256]

daft nord lots of software do that. I use CamScanner for being completely free

[@daftnord4957]

Lance Lindle Lee I'm sure, the one I mentioned is just one I recently used

[@حاسب-1]

Thank you this channel help me in teaching and somewhere i can tell my curious students to follow

[@JyotinderSingh]

That skit in the start was so professionally filmed

[@isypa2180]

Probably the best intro yet.

[@sampathbalivada-personal]

Make a techquickie on Movie 2d and 3d cameras, the storage devices they use and the post production softwares they use.

[@jimbo33]

Excellent roll out like a drum scanner! Very impressive sound effects also 😆 Great video! Thanks.

[@cleitonalves3282]

Great explanation!

[@aunairqureshi816]

Thanks

[@tuna_land]

Woo Luke is back!

[@djSpinege]

the intro was a good guess but i just hit a huge dab and started to wonder after i remembered i scanned my butt once like 17 years ago.

[@csabafazekas7266]

Noob Luke... The scanner doesn't work like that. Little chinease people sit in the scanner and looks at the image you are trying to digitize. They convert it to binary image and they send it to the PC via the usb cable. This is why the box itself is so big.

[@cloudy7003]

"chinease"

[@skipperbee3504]

Csaba Fazekas racist!!!!!!!!

[@ashboon1625]

Hye!

[@TradingFeline]

No it's Japanease

[@niq872]

thats only if you buy the better quality options

[@cwalshie]

Would love a video on what scanner to buy!

[@coolkidsahib]

Can you do a video on Codecs? Especially codecs like Cineform (that you guys use, or any others)

[@K_Calla]

He's back?

[@Terryplaysguitar]

Very entertaining as ever Luke. Put a smile on my face

[@GaudyMarko]

my scanner is built into my printer and not gonna lie, for me, buying a printer comes down to which option has the best value refill cartridges. I'm sure a professional photographer or whatever might care about performance and junk but given the prices on toner and ink these days; you could give me the world's highest quality printer/scanner for free and I'd still feel ripped off when refilling the printer 3 times costs more than a new printer, which is often the case.

[@-0-__-0-]

Ever played a game then suddenly a black loading screen pops up and you see you reflection, then suddenly your wondering, how did your life get so messed up?

[@nitinmann]

yes please suggest what scanner is good

[@VideoProLoader]

The dramatic scene is hilarious.....XD 0:38 "How your life got to this point...????"..... .... .... Well I'm wondering how did my life got to this point where I'm watching this video too.....XP

[@mokshmaru]

0:00 best introduction

[@trektn]

Just realized this was a techquickie video and not an actual ltt video

[@osamayshak]

Yes make a video about what scanare to buy. not because i want to buy one, but because it can be a good reference for when i want to buy one / upgrade from the one i have. also nice video btw. :)

[@boomperson818]

whats the music piece in the beginning of the video?

[@impokejon2908]

It's actually 1:07 p.m. right now and I have seen this video 3 times so everything you said in the first 47 seconds of this video was true for me currently. Also I'm in the living room and there's muted reruns of Dragon Ball Z playing over DVD on the Blu-ray.

[@David_Quinn1995]

thats acctually cool, I have a older scanner it has to pass 7 times for color mode but it works and im satisfied with what it does till it dies

[@DonalTechTips]

I read the title as "How Do Scammers Work?" and it took me a realize it was all about scanners!

[@ThatBeTheQuestion]

Nice Pixel!

[@zero80473]

forgot to mention Old Hand Scanners as well lol.

[@shahrukhlandge4079]

wow. u just helped me alot thanks

[@amdkillaplays]

Yey Luke is back! 😂

[@johneygd]

Well am coriouse about those drum scanners you mentioned at the end. So i would say do a review of it.

[@jello1977]

Does the same apply for digitising films/35mm slides?

[@chrits3396]

I hate it when a friend calls me at exactly at 2 AM and asks me to make a copy of a specific document placed next to a bag of cheese puffs for no particular reason.

[@Joshverd]

"Crappy built in camera" PFFFF thats a pixel!

[@ayeshaxhk]

amazing explaination

[@Kaelygon]

Lol It's 2Am and I am watching Techquickie.

[@peterl1699]

Nice was this filmed with the RED camera?

[@MemeFactory34]

Ooh I'm early to a techquickie video

[@aaronazzcalibur4261]

video on how dac's work and what to look for when buying them. PLEASE !!!

[@jwenneberg]

Please... I have wondered why my old scanner were able to scan the inside of a CD jewel case without any area being out of focus. My two latest scanners hasn't been able to do that, which is why my hmepage hasn't been updated for four years now :-( Do I have to look for a CCD scanner instead of a CIS scanner to achieve my goal? Thank you so much if you can help.

[@IntrophyGamer]

Drum scanner looks oddly terrifying

[@aaronbigleman7326]

Oh please, LMG, tell us how fax machines and pagers work next!

[@RaydeusMX]

TFW you realize 30 seconds prior to the beginning of the video Luke was going all DeadpoolxPony with that Vader doll...

[@marcusireland5696]

linus what is auto iris on epson projectors plz explain

[@msujonbd]

Nowadays there are some good scanner apps for phones. The apps fixes light issues, and automatically fixed skewed images. The results are comparable to common desktop scanners.

[@Belos_Charlie]

I actually learned something - I was unaware of the mirror structure. The rest was info I already knew, but was entertaining regardless. I would definitely like a scanner buyers guide - perhaps a more in-depth LTT video instead of TechQuickie?

[@TheDyingFox]

I have the HP Envy 4500: Scan resolution: Hardware: Up to 1200 x 2400 ppi; Optical: Up to 1200 ppi Scan technology: CIS Not sure what they mean by the "Optical" (vs Hardware) part in this case, and "up to" (probably just selectable resolution). The scans are ok as far as I know (Nothing to compare with, was cheap printer/scanner though $73.81 for a new one at my local store... needed a printer, got a scanner for bonus... YAY!)

[@udohpele1696]

Wonderful intro. Wonderful. 😅 very informative

[@cracklingice]

I had cold cathodes in my PC back in like 2006 so it's pretty safe to say more than a few years ago. lol

[@Platinumdose420]

i cant remember the last time i used a scanner, but thanks!

[@LovSven2011]

Something *incorrect* at 2:55 - 3:20 "contact image sensor or CIS (...) use an array of LEDs (...) image sensor can essentially take a *snapshot* of it like you were trying to do on the table with your cell phone, but better." So, I don't know if snapshot (meaning whole page, not just one line) is done with CIS. However, it works in *direct contact* with the document, UNLIKE a snapshot with a cell phone or any camera that photographs objects *at* *some* *distance* from the lens. !! Incorrect comparison. Who even wrote this??

[@LovSven2011]

My opinion is that _scanner's advantage_ over camera is that there's *no* *spherical* *distortion* from the lens to correct (depends on the distance to the page photographed) and *lighting* *is* *controlled* by the device taking a picture. (putting aside all other factors that affect quality)

[@baldimath7585]

Very cool and complicated

[@julianlobo9753]

When you mentioned CCDs I was like "Omg!" cause this devices are also used for transmission electron microscopes where they need to perform the inverse process of going from an electron beam (electricity in a vacuum) to an actual image made of light.

[@RocketLR]

Thats allot of noise in the video :S what camera did you shoot with and with what ISO? :S

[@MoosaMahsoom]

LMG showing off their red camera's dynamic range in this vid.

[@ng1nx140]

Did you use your red cam?

[@vgamesx1]

Everything mentioning the Pixel but nobody is pointing out how most phones also have a flash you can use as a light, as long as you don't get too close or far away then it should be adequate for taking photos of a document.

[@casekocsk]

After you realize your crappy camera phone and the poor lightning doesn't help, you dash out the house to buy phone with 4k camera and a good lamp.

[@googlecrome2887]

love the vid, keep it up!!

[@KevinAlexMass]

The background music.. Any link please

[@josephs.7960]

rip dude. Did you find it?

[@mememe84]

how did they used to put images in books and newspapers before computers and scanners?

[@MichaelSodapop]

I'd like to see your next video being on the best & best per dollar combo: print, scan & copier.

[@hamilpatel4025]

cool video, no follow up. video: printers? fax? how are school/college computers set up to be linked together?

[@2EXTREME2008]

Yes please! I want to see a scanner buying guide from you guys! :)

[@sparkythewildcat97]

Think you could a video about AVX? I know that not having AVX is one of the differences of a pentium or celeron compared to intels i3/5/7 CPUs, but I can't find any good videos made in the recent past that explain it.

[@aldenranberg]

WHAT SCANNER SHOULD I BUY!!! My gf recent started doing mixed media art projects and a higher quality scanner is in the future.

[@valivarthisriharivarma5852]

Hi Buddy can u suggest me a scanner for scanning bulk books and also providing ocr services ...

[@jpchevron]

Finally we see that nVidia sponsor contract.

[@ayeD356]

nice build up!

[@lukemckenna]

I would very much like a buyer's guide to scanners as I'd like to scan a ton of old pictures, preferably adding metadata as I go.

[@TheSweetChinMusic1]

0:30 that is why office lens exist...

[@analkarlderzweite6349]

I'd like to get some advice about scanners (and maybe printers?) from you guys.

[@analkarlderzweite6349]

I want to buy a laser printer with a built in scanner in the future so that I don't have to worry about wet paint drying out in there since I rarely print things.

[@Gockodile]

Finally I know how my 300 pound scanner works. If only I could figure out how to get it out the apartment

[@Xeando]

0:45 is the start

[@OndrejFoukal]

Gooood!

[@iamdantheman360]

BEST LTT INTRO EVER!!!!

[@eugenebodnarchuk2822]

can you do one on eSata?

[@__-cd9ug]

Save the soy cider from soggy fleece lace Salty seaweed was served at the principal's second anniversary Guess the sender of the seventieth message on my cellphone The strong smell of salt slides up your nose

[@dillonblevins3364]

I want to know more about the CIS scanners... How does it work - but more fleshed out for ignorant, non-techs like myself. I want to know how thin this can possibly be made. Is it plausible to have a scanner as thick as, say, a book cover?

[@supreme84x]

Ooh. I read the title as how do scammers work. Based on the theme of the channel, scanners makes more sense. :-)

[@SarimAshrafi]

Filming is cool... Love it..

[@mccoolguy8176]

If your phone camera is bad use the 4k one you are filming with easy right

[@theodoros_1234]

lol it was actually 2am when I started watching this video.

[@baldimath7585]

Very helpful

[@Lambda_Ovine]

I want to digitize my drawings. I want to make sketches on paper and then coloring digitally. What scanner should I use? I also don't want to spend crazy amounts

[@cgreen339]

Did this guy just have a full office scanner in his living room??

[@triochalas]

I like when Luke talks more than Linus
