Thanks Alan for the clarification and comment.  Makes sense.

still have green pixels?  RYYB  - no green.  Maybe you meant something else? ======== Anyway, in general, it could just be a different color correction matrix with a different set of coefficients. ...

A hyperspectral imaging camera or imaging spectrometer can do this already. Not sure I see a big advantage for QIS in this application.

Well, perhaps you have had different experiences competing with Sony.  Let's just say I have had some experience in building startups, product development and manufacturing, and competing with ...

Sony is the 800lb gorilla.  Once they decided to go into CMOS image sensors, they invested billions of dollars in fab capacity and R&D. They only licensed the CMOS image sensor technology from ...

LMAO!  good one! Sure, maybe they will acquire Gigajot some day.

I don't like wasting photons either, but I don't know of a way that works at room temperature and can be built from existing technology in multimegapixel arrays at reasonable cost....Not to ...

Thank you Jack, both for the kind comments as well as the questions. I cannot answer most of these alone as they are beyond me at this time.  But I will encourage one or more of the co-authors to ...

For those that may be interested, here is the first work on a color QIS, which is really about image denoising in a photon-counting image sensor where Poisson statistics are part of the denoising ...

wish I could edit this, but, duh, replace "sqrt of the sum of the squares" with "sqrt of the sum of A and B"

Bill, maybe this helps. Take two photon signal values, A and B, both of which are large but slightly different.  A and B both have "noise" that is like the sqrt of the values. (technically there is ...

Well, slight differences in performance are very important to audiophiles when it comes to sound. You are mostly right. Many sensor manufacturers buy their CFA from Fujifilm, for example, though ...

I hit "like."  Your lips to God's ears, as they say!

First things first, I did a screen grab of a page of the article PDF, as published, including the caption. I would not use that pixel count at all.  I am guessing the original image was 256x256 as ...

Thanks Jack.  The company is focusing on applications where QIS has a compelling advantage. Beyond that, the company is not saying anything, as is pretty normal for an itty-bitty company that does ...

OK, you are right. You said "the way that the colour filters work" and I guess you meant color discrimination.  I was thinking literally of how colour filters work.

Laser Focus World, a trade magazine, published a short article we wrote on the Quanta Image Sensor (QIS) (December, 2018).  You can find it on their website, or perhaps more directly you can view it ...

Probably you mean the EFFECT of quantization - being Poisson arrival noise aka photon shot noise. Not sure I follow this comment. Are there polymer color filters in my retina?

You have indeed identified a feature of digital imaging, but with all due respect,  I do not agree that digital storage is itself the essence of digital photography. Digital optical or radio ...

The human visual system is also discrete. Our brain does a good job of making the world look continuous (as it is for the most part at human scale). To the extent that we can accept computational ...
