CCD versus CMOS - advantages and disadvantages explained

Hi Folks,
I'm working on some video's that will discuss main differences between camera's that are often used for astrophotography. In this video, I try to explain the main advantages and disadvantages of cameras that use CMOS versus CCD sensors. I hope you like it, and please tell me which camera you prefer.

Here's a more recent video where discuss astrophotography camera's ua-cam.com/video/HhIAEnVMzHU/v-deo.html

Someday a video explaining those graphs everybody shows on those astrophotography camera pages would be good. They mean nothing to me.

[@AstroForumSpace]

I'll see what I can do :-)

if you scroll your YT feed long enough you might find exactly what you need. now that's official for me.

Nice video and really a helpful one! But one thing I am not clear is around 8:05 when talking about the low read noise of CMOS. Is this feature caused by the 12-bit ADC? Or, in other words, the read noise of 12-bit ADC is lower than 14-bit ADC thus lead to a lower dynamic range but better high ISO performance? Thank you!

[@AstroForumSpace]

Hi Henry, thanks. As i understand it, the CMOS technology has matured a lot over the past decade. Where CCD sensors used to have a lower read noise as the 14bit adc is placed outside of the sensor, CMOS which includes many ADC converters on the sensor, has caught up with most CCD sensors, and some even outperform CCD sensors in terms of read noise. You're right about the dynamic range. Clear skies!

[@henrydong3105]

AstroForum Get it and thanks! CMOS is developing so fast and has overcome many original drawbacks.

[@CEEPMDEE]

I prefer CCD sensors.

[@AstroForumSpace]

If you have the money, go for it.

[@CEEPMDEE]

@@AstroForumSpaceI have a classic Canon 1D 4.2 megapixel and a Pentax 645D. They were not very expensive.

[@estudio_peso]

I don't understand - mostly because I am a beginner. You mention CMOS being the cheapest, but why is canon and phase one opting for this type of sensors and asking a lot of money for them? It would be great if you could light me up on this.

[@AstroForumSpace]

Thanks, but I don't understand your question. CMOS sensors are the future as they are mass produced for smartphones, DSLRs and astrophotography cameras. As a result the CMOS sensor is much cheaper as compared to CCD sensors.

@@AstroForumSpace fast food world uh ;) From 2007 to 2014 I used a Nikon D200 (10mp CCD), from 2014 till now I am using my EOS60D (18mp CMOS) - The image quality in the D200 images are far superior than the ones from my 60d (IMO) considering the limitations based on the sensor's pixel count. I may sound stupid when I say that "I wish camera manufacturers developed CCD sensors to make it a much more viable option" - Yeah news photographers can't wait for hours for their shots to be read out and tweaked to publish in this highly competitive world. Nevertheless I am more partial towards CCD than a CMOS..and I don't know why.

[@MJ-uk6lu]

I don't understand how CMOS sensors were promised to be as much as 100 times more power efficient, but somehow no CMOS camera can boast even 2x battery life to comparable CCD camera.

[@visualchallenge2413]

You said @ 04:09 "each column has its own ADC". That is a lot, I never heard of that great number. Can you please give me a reference ?
By the way Thank you for this instructive video.

You'd be blown away by modern sony sensors then

Lekker lekker

[@dushyantbhatt9345]

NASA uses CCD sensors for all their satellite's some reason,.. do you know why ??

[@AstroForumSpace]

They are old school :-). Until very recently CCD had a higher quality analog-to-digital converter and better signal to noise ratios than CMOS. It's only the very latest CMOS cameras that are rivalling the quality of CCD's.

[@dushyantbhatt9345]

@@AstroForumSpace ok... I think CCD is still batter & give better accurate colours renders green/cyan/blue channel better then latest CMOS .. my observation

[@AstroForumSpace]

@@dushyantbhatt9345 perhaps, but they are also more expensive.

a good video. nice explanations, but not very clear on the differences between both types of imaging chips. The explanations would have been far better if video examples of the same footage filmed with 2 different cameras, one with a ccd and the other with a ceos sensor would have been very helpful. Then, the explanations and definitions the filmmaker provided here would have made better sense while he showed and illustrated the underlying differences of the different definitions he provided of both types of image sensors.
His accent, though a bit heavy wasn't too bad. But he did far too much hemming and hawing with the pauses and all of the "awes" he used at the end of each and every sentence. I missed a lot of what he had to say because of the excessive hemming and hawing, which was very distracting. That and the fact of, although his descriptions and definitions were good, and he provided some very decent animation of what he was explaining, the combination of a lack of adequate demonstrations to illustrate his definitions and his hemming and hawing, leaves this film with much to be desired.
Try using a script next time. Have more info about the products, including actual video footage of that product. In this instance, it has to do with imaging sensors common to videography and video cameras and camcorders. Side by side comparisons between the 2 different sensors are essential and provide better information and detail to what you were trying to say and illustrate. Like I said, it's a good video butt... try using a script, and provide better info and illustrations to your descriptions like videos of footage, and images of the 2 different types of cameras and the sensors they use. However and in fairness, I did learn something and gained a better understanding between the 2 imaging sensor types. Thank you.

Hi JW. I completely agree. The main reason why i didn't include a comparison between pictures taken with a CCD vs. CMOS is the simple fact that I do not (yet) own a CCD camera. I would love to make such a video. And yes, I have to work on my "awes". Thanks for watching and your feedback.
