Image Sensors as Fast As Possible

Image sensors allow us to have amazing cameras in all types of devices, many of which are becoming smaller and smaller all the time... But what makes these sensors so darn impressive?

Anyone else catch the 2 in the binary numbers at 1:53 ?

CUDA CORES vs STREAM PROCESSORS PLEASE

[SeanDaPaulSeh]

this guy's voice is sometimes hard to listen to, but this is just the video I needed to watch, answered all my questions

[mcb]

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!

[EmBeeSeven]

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.

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.

Yes I totally and completely understood everything in this video because I'm so smart... *cough*

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.

Nigga I'm leaving here even more confused about image sensors.

[DigitalMonsters]

*nods*, *nods*

So they work through magic.. Got it!

Linus lost me at 0:15, after that i just zoned out and realized it was 4 in the morning

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).

[incjumpStARtR]

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.

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.

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.

Was that whole video done in one take? BREATHE LINUS

[MrTitskie]

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

[shajibhatti]

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

The voice cracking at the start of this video makes me love it all the more
