Huawei to use liquid lens in its 2021 flagships

I've been waiting for these ever since I first read about Philips research into liquid lens technology way back in 2004 (!).
Just goes to show how slow it is to bring techn innovations from lab to the market.

AnonD-909757, 27 Nov 2020Yeah, nice.
But what about no punch hole/notch/underdispla... moreSamsung and LG are working on these types of screen, first you need a screen that allows you to take photos with selfie quality from under it. And also to develop the correction software to eliminate the pixels that are between the screen and the objective of the photo.
But I hope that by 2022 we no longer have phones with that horrible hole drilled and no motorized cameras are needed as they remove the waterproofing.

Iphone has better innovation than Huawei, look at latest triple lens on Iphone 12 Pro. It is first with such nice image quality in a smartphone.

Wrong again. From Wikipedia:
"Rolling shutter is a method of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, either vertically or horizontally."
"Fast shutter is.."
"Burst mode cannot.."
I'm sorry but I don't see how these are anything to do with the point that I'm trying to make?

One of the main advantage of using QB sensors is that you can achieve high sensitivity while having high MP count at the same time. Since noise and (lack of) dynamic range is far less of an issue on a large FF sensor than on sub-1 inch mobile sensor, there's not much point of using them over traditional Bayer sensors on mirrorless/DSLRs.
"Sony, the company that has 51% of whole sensor market says quadbayers are slower to be entirely readout"
Any source that Sony *explicitly* stated that? As far as I could tell from the slides of Xperia 1 II announcement, all they compared to was Samsung's Nonacell HM1 sensor which is already said to be slower than equally sized Tetracell GN1 sensor. Not to mention that physical sensor size also affects scanning speed, and IMX557 is nearly half the size of 1/1.33" sensors used by many high end smartphones.

Rolling shutter is video related.
Fast shutter is what try to keeps photo blur-free for single frame.
Burst mode cannot even be brought to the chat because only one brand offers AF while doing burst. Something all phones above $600 should have.

Not to Quadbayer 12MP, because it does not exist, also it would be made to work at 3MP.
48 and 108 even doing 12MP photos are much slower.
There is a FF 61.2 MP quadbayer. None has interest in it.
Zero advantage.
Sony, Samsung and Omnivision push this tech because it is cheaper to make and they can milk tons of money from the innocent OEMs.
Sony, the company that has 51% of whole sensor market (not just mobile sensors) (Samsung is the #2 with 17%) says quadbayers are slower to be entirely readout. But Nick and Shanti say opposite.
Who should we all trust?

Shanti Dope, 27 Nov 2020What? Lol it seems like you don't understand the whole... more"ISP of the phone still records all data from all pixels in the sensor, and that alone already takes longer than the same process on a native lower resolution sensor"
Note that you said "native LOWER resolution sensor" - your point is not answering to my previous comment that compared two sensors (one with regular Bayer filter, another with QB) with the same number of pixels.
The time taken for demosaicing is irrelevant when you're comparing, let's say, 48MP QB sensor (in binning mode) and 12MP regular Bayer sensor, since 4 pixels are treated as 1 pixel in the former thus only requiring the demosaicing for 12 million pixels, which is basically the same as the latter. It will take longer time for ISP to process the image if and only if the sensor is read out in full-resolution mode.
Going back to the original question: ASSUMING TWO SENSORS HAVE AN IDENTICAL MP COUNT, does a Quad Bayer sensor always have much faster scan speed than a regular Bayer sensor? The answer is, absolutely yes. Just take any phone that has a QB sensor and shoot fast moving objects in both binning mode and full resolution mode, and you'll see that the rolling shutter effect is far less obvious on the former.

Awsome new tech which will soon be available to the world. Except US, which can settle for soon to be >$2k iPhones and crappy Exynos gadgets.

The only smartphone and high tech company which actually invests in development of new products. It's clear why US hate Huawei so much and tries to slow them down. Not gonna work.

Nick Tagataka, 27 Nov 2020"Let's remember, non-bayer sensors are much slowe... moreWhat? Lol it seems like you don't understand the whole process correctly.
Even at binning mode, the ISP of the phone still records all data from all pixels in the sensor, and that alone already takes longer than the same process on a native lower resolution sensor. That's just one part, and the other is demosaicing. A high-resolution sensor simply cannot take rapid burst shots while the SoC is still processing the final JPEGs of previously captured images, and that's the sole reason why the Galaxy S20 Ultra/Note 20 Ultra, P40 Pro/Pro+, and every other high-megapixel camera phones cannot do the 20fps AF/AE burst of the Xperia 1 II and 5 II.
The lower resolution allows the phone to bring down the capture time from the sensor to 10ms, compared to 32ms or more on high-resolution sensors.
This is the only answer to this topic. The process of how Quad Bayer or Nona Bayer sensors has anything to do with improving the speed capture. Again, more megapixels to work with = more time needed to process and save data (assuming everything else is comparable, like the ISP used, sensor size, processing styles, etc.)

anyway, the way Huawei progressing....seems the technology where Ghost in the Shell series is shown probably will realize sooner or later.
Cyber eye tech with focus as fast as the human eye is something interesting and exciting to have.

I love it when manufacturers pushes new technology beyond. Sure it gets expensive at first but as time flies andanufacturing costs comes down, perhaps in the not so distant future all can enjoy the tech without breaking the bank.
