[Q] Is pixel binning also possible for the still camera? - Galaxy S II Q&A, Help & Troubleshooting

Pixel binning is a mechanism to use 2 (or more) pixels of the camera sensor to create 1 pixel in the final image. Pixel binning is basically trading resolution for higher sensitivity. This significantly helps to reduce sensor noise in low light scenes.
The video camera of the SGS2 seems to make use of pixel binning when recording in 720p. The sensor resolution is way bigger than the video resolution of 1280x720 and so sensor pixels are "combined".
Now I'm wondering, if pixel binning could also be used for the still camera. While the camera can take great shots at day light, it has (as most digital cameras) significant noise issues in low light scenes. The still camera could really benefit from pixel binning to create well exposed and less noisy images. I for one would love to have the possibility to trade some mega pixels for noise free, low light images.
Code:
aspect ratio | normal resolution | possible pb resolution
4:3 3264x2448, 8mpx 1632x1224, 2mpx
16:9 3264x1968, 6.5mpx 1632x984, 1.6mpx
Does anyone of the developers see a way to enable pixel binning via a (software) mod for the still camera?

Recording 1080p video - Camera is zoomed in. Why ?

When recording in 1080p using the camera it is zoomed in. When using 720p you can see a lot more in the picture, where as 1080p seems to zoom in on the central object.
Now I was just wondering is it possible to mod this to make 1080p video record without being zoomed in (like how 720p does it) or is it impossible and it has to work that way ?

Check out the video recording review in gsmarena.com

Here's a thread about it if you want more detail.

when the sensor chip (the camera) cannot crank for example 30FPS at 1080P resolution, "zooming" is a trick.
The sensor has less surface to scan with the zooming and can then crank out the said fps at said resolution.
The exynos chip however does "real" 1080p encoding and the image is really 1080p, but appears zoomed, and therefore contains slightly less details than if the sensor did not zoom (since parts of the field of view are not viewable)

So would it ever be possible to have 1080p video without 'zooming' by modding the firmware/ in a custom rom?
Or is it hardware limitation ?

Physical Hardware limitation
Native res of sensor = 3264x2448
HD Video = 1920x1080
3264 / 1920 = 1.7
so the only way to record 1920 is to bin the .7 thus cutting out much of the screen.
now 720p HD only has a horizontal res of 1280 that goes into said sensor 2.55, so you only need to cut out the .55 (less than full hd) and then read alternate pixels and bin the rest.
Hope that makes sense

I think that even binning the 0.7 factor should give a better result than the actual "zoomed in" effect. In the other hand whe should have the zoom function at 1080P resoultion too.

Humm... i'm still dubtfull about this limitation. Correct me if i'm wrong, but i think that the htc sensation is able to apply digital zoom @ 1080P, and it should have an 8Mpixel camera too, isn't it?
I can't post a link but if you searc for "HTC Sensation takes FULL HD 1080p videos " in youtube you will find a video taken with htc sensation with digital zoom!
I don't think that the galaxy s2 hardware is unable to do the same thiks that htc sensation does...
Oh, digital zoom is easy, but a bit pointless. So no point zooming if your source resolution drops, why not record native at the lower res and increase on pc? You will get better result that a phone attempting bilinear calculations .. So probably excluded cause of it being pointless.

Hi
digital zoom during video recording is not applied by a simple bilinear calculation. Its quite the opposite:
No zoom -> use the whole sensor area and then "downsample" it to obtain the desired dimensions
Zoom->Sample the exact dimension from the center of the sensor.
Infact, if you watch two videos of the same scene taken with the sgs2 720P and then 1080P, you will notice that the 1080P gives a zoomed effect, becouse samsung only uses the rectangle on the center of the sensor to sample the frames, while with 720P uses the whole sensor area.
Power limitations? Unskilled Samsung's engineers? Who knows..

I don't think that it's neither power limitations or unskilled samsung engineers. At 1080p, it uses most of the sensor, so zooming in will decrease the quality of the image to the point of being pointless at filming 1080p.
The reason why 720p uses the entire sensor area is because it does something called pixel binning. It uses the adjacent pixels to determine which color/info is more accurate (so a single pixel in the middle uses the ones around it to determine which color is closer to the actual source).
See here for more info:
http://www.svi.nl/PixelBinning
With pixel binning, you get less noise but at a cost of lower resolution. Therefore, they implemented zoom for 720p and the reason why 720p uses the entire sensor.
So the reason for why the 720p uses the entire sensor and 1080p only uses a section IS due to hardware limitations. 1080p needs at least a 12.4MP resolution for pixel binning.
As there is pixel binning, 720p will produce higher quality zooms than if 1080p could've zoomed using crop and bilinear enlargement (which will create pixelated images). That is why I assume they didn't include 1080p zoom - for quality purposes.
BTW - pixel binning is a technique also used by the iPhone 4.

Thats wrong! It's only correct if the sensor has the physical resolution that surpasses the target res by 2 exactly! Look at my previous post, I explain it a bit better. Your taking about sensor crop and pixel binning, not digital zoom.
Oh and bilinear is not simple, when you think of the amount of subpixel influence you have to create.
Neways, point is digital zoom creates pixels from thin air, well, programatically. So the detail is not present, hence why digital zoom is a consumer buzz than a valued feature.
Thanks for your replies guys. I would like to bring two more arguments for my theory:
1) The 720P recordings that we can find in the net shows a low quality zoom
2) In the other hand, there are some videos taken with the htc sensation that shows an almost perfect zoom @ 1080P
The question is:
if the htc product uses virtually the same sensor of the sgs2, how can they implement the zoom??
Here a video sample with digital zoom @1080P:

The answer is: Digital Zoom lol
Tis easy to see in the video that detail is lost, pixel get bigger then filtered etc. So Digital Zoom is a software feature, not hardware!
Also people seem to forget a few very important things regarding capture quality, the bitrate of the encoding profile in use. From what I see the sgs2 has a variable 10-14mbit profile active for full HD. Some of my pro cameras use 35-50mbit. So I'm going to look into how to mod this if i can since the hardware should be able to handle a higher rate, busy at the mo though.
at the end of the day though, tis a phone, if you want really good quality get a pro sumer hd cam, or a 5dmk2, or if you won the lottery get a Red Epic and shoot 5k res at 1000's fps. However none of those have mail/chat or phone capabilities
for 1080p are taken 1920x1080 pixels from the center of 8Mp sensor... (in this manner there is a "zoom effect" of about 2x and less view)
for other resolutions are applied pixel binning tecnhique (all pixel from sensor are used, and is scaling from 8mp to output video resolution)
take original pixels produces better quality (because are original pixels and not scaled), but less signal/noise ratio (but, because galaxys2 sensor is good, noise is low also if you take original pixel and don't use pixel binning that increases signal/noise ratio)..
also, use original pixels and don't use pixel binning, requires less power (in this manner you can have 1080p video at about 30fps and high bitrate)

Ok deanwray, you're perfectly right, but i would prefer to choose by myself if i wish to use the zoom or not, awared that if i use the digital zoom, the quality will be affected. In the other hand, in this way, the 1080P video would have better field of view (instead of the zoomed effect we have now) and less noise.
About the bitrate: maybe it's possible to raise it to 20Mbit, but i think that going above this limit is quite difficult. According to me, it's better to implement the zoom in 1080P and a better audio recording.
I was thinking: if they're unable to implement such features... how can we hope to obtain higher bitrates.. ?

If it's not firmware (camera firmware) limited, there are calls in the android sdk to set bitrate, I would probably look at writing a camera when I have time. Never looked at attempting to mod the default one. Have found something odd though, did a few tests, and there should be perceptual zoom due to sensor cropping at 720p, but compared against an 8mp photo, there aint! So thats a bit wierd to me

According to you, is it possible to modify/create a camera app that implements a digital zoom or better algorithms for image sampling?
What kind of access is possible to gain to the application processor's peripherals with android os?
There are some realtime image scaling algorithms that could be implemented via gpu or, better, via dsp if the exynos integrates a dsp onboard (like the TI's omap do).

Binning to improve night shots

Most reviews of Mi5's camera say it's pretty good in good light but not so great in low light conditions and I agree with that.
I wonder whether would be possible to use 2x2 binning of pixels to reduce resolution but also noise in images
Using this option for example in HHT night mode would provide 4Mpixel images (one quarter of full resolution)
but much cleaner and less noisy.
I had a look at datasheet of Sony sensor and it seems to support natively binning,
any idea how to have this function managed directly by MIUI ?

Poco F1 Front Camera Fix New Finding

Hello devlopers and friends Ever since I brought poco f1 and installed gcam and other third party camera apps my front camera resolution drops to 5mp. Only official camera app is able to use 20 mp resolution.
I know there are many threads about pixel Bining and stuff but i don't agree with them. The main problem is at the end a 5Mp Image is 5Mp and 20 Mp is 20 mp.
But i think and request devlopers to please look to it.
## According to my theory As confirmed by Device info Harware app There are three camera sensors in poco F1 out of which the one with camera ID 0 is 13 the one with camera ID 1 is 20 and with camera ID 2 is is 5 megapixel.
"
13 Mp back camera primary Camera Id 0
5mp back camera primary camera Id2
20 mp front camera Id 1
"
According to my theory the five megapixel and the 20 megapixel camera are conflicting with each other and gcam is taking the values from 5 megapixel instead of 20 megapixel sensor. So I request that developers that they can try I and confirm if it is the case and if it is true please make a fix for it
thanks
On specs sheet, the front facing camera has 20mp but in gcam it says 5mp. Google Camera is using what they called "Pixel Binning" and it is a software implementation.
This process is the procedure of combining a cluster of pixels into a single pixel. As such, in 2x2 binning, an array of 4 pixels becomes a single larger pixel, reducing the overall number of pixels.
13mp back camera is the main camera shooter
5mp back camera is the depth sensor
20mp front camera is the secondary camera shooter
One good example is this

The question is that why gcam and other apps detect only 5mp sensor.
Lets agree gcam uses pixel Bining and stuff.
But why other apps detect and capture 5mp are they all using pixel Bining.
And why only Mi Camera can capture at full potential of the sensor. Is there a catch we all are ignoring.
Pixel Bining or not at the end when zoomed 5Mp image is storing lesser data .
And also imagine a 20mp full resolution shot with gcam cam make things go from OK to wow.

It doesn't really change anything. And it doesn't mean more resolution = more quality. It is a matter of fact of image processing. If you really compare MIUI Stock Camera and Google Camera, you will see the big difference from the two since that Stock Camera doesn't uses Pixel Binning algorithm

Pixel binning gives better shots in low lighting conditions only. No significant difference in well lit conditions. Thats why i want to capture with full resolution in Google camera because its awesome.
Also if pixel binning is so justified why don't we capture 3 mp photo with rear camera and say its better than 13mp because its not
Justified ( That 20 mp shot from miui cam is not good than gcam)
Not justified ( That it is due to only pixel binning . It is due to google computational algorithms.)
#pixelbinning is justified only in badly lit photos not everywhere
Agreed doesn't mean More resolution=more quality
But More resolution =More information per inch in captured shot ( in case of gcam it means awesome shot)
More resolution =More information per inch in captured shot ( in case of miui camera it means ok shot cause it does not uses multiple shots and algorithms to produce good shots)

Then use the stock camera if you really wanted the 20mp. Use gcam if you wanted better image processing.
This was explained a long time ago and it is really not a big issue or some conspiracy about the 20mp sensor
Yes it is a issue One plus devices had this issue Zen devices had issues similar in Auxiliary camera regarding resolutions on gcam. All those were fixed due to efforts of devlopers.But i think people just want to accept everything and not work it out. If some one can try to find a fix there will be a fix. But if everyone just accept the fate lie down nothing is gonna happen
Similar issue, i can't change photo camera resolution on miui 11.0.5.0.

Dude, you are suggesting your gcam is taking front selfies with rear 5MP sensor?
A 20MP image is only twice as big 5MP image. Not 4 times big.
Gcam 5MP selfie carries much more details than 20MP MiUi camera, day or night. Period. MiUi camera does a lot smoothening.

Or maybe gcam does lot's of sharpening to make them look "detailed" zoomed out? When zoomed in you can see tiny coloured squares.
Update I used Redmi note8 Pro and Redmi k20 pro with gcam They all produce 5 mp front and 12mp back irrespective of the sensor resolution. Maybe gcam only supports these resolution maximum.
Honestly i would love larger resolution support with gcam .
In k20pro gcam can take images in 48 MP resolution
In back But issue is in front it only takes with 5mp resolution and this 5MP resolution is useless when you zoom the image or see it laptop you can see amount of noise.This really need a fix .
Can i disable Pixel Bining
I think no devloper is interested in This.
I wish there were devs who would look at it but sad thing is no one really care
True story
Actually Gcam detects full one Megapixel when individual pixel size is more that 1.1 π size..
Poco f1 or other Xiaomi phone with 20mp sensor has individual pixel size of 0.8/0.9/1.0 π size.
But Gcam detect full 13mp in my Redmi note 5 AI because the sensor's pixel size is 1.12 π.
Thus even in my old device has a 13mp insane Gcam selfie.

Question Pixel 6 50MP camera sensor : Storage requirements

Wondering how much storage space will one picture take for the Google Pixel 6 take with the new 50MP camera. My current Google XL 2 using a 12MP camera would take ~5MB/picture.
The sensor uses pixel binning, so the output image is 12,5 MP.
The binned picture file size is also worryingly low. I wish they gave us more.optiions to select and store higher quality images and video.
You can always save in raw + jpeg, though I'm not entirely sure if it processes the raw image
This main 50 megspixel camera is compressing the photo so much that having 50 mp is useless. Too much compression and still using their computational technology at 12 megapixels so we aren't really seeing what the difference a 50 megapixel camera would make. File sizes should be 25 mb or higher with a jpeg at 50 megapixels. Yes I'm a photographer

You are right. Apart from some improvement to noise levels and colour, the details are virtually the same as my pixel 4xl.
I think the only real benefit of the 50MP sensor is when you zoom (hopefully). So when you zoom in it no longer pixel bins and you're using a native 12MP section of the sensor before you get into digital-only zoom.

I haven't found that to be the case. There is a 2x zoom that doesn't look too bad (slightly oilpaint like) and a 4x that is the optical zoom on the telephoto sensor that's very good... Another issue is the camera automatically switches between the main sensor at 4x and the telephoto 4x sensor depending on focal distance so you can't use the 4x optical to take close shots.
So what's the point of a 50MP sensor binned to 12.5MP if it always does it? Why not use a native 12.5MP sensor and get even more light in, by avoiding the gaps between the pixels used in each 'bin'?

As above, better noise level and light input.
Definitely better pictures on the main and 4x sensor than the pixel 4 xl for sure.
I just wish we had a full size version and higher quality image export.
So using 4x small pixels in a bin is better than one big one the same size for noise/light (assuming the technologies are the same)?
Ok so that seems to be the case

Photos would be much better in well-lit situations using 50 megapixels. Pixel binning down to 12 megapixels would be fine in low light but it's not acceptable to me to do this in well-lit situations. They need an update for the camera to decide when the situation is lit well enough to use the 50 megapixels and to decide when it's not lit well enough and use the 12.5 megapixels as they are. Because regardless of what anyone thinks s 50 megapixel photo would have much more detail than what's being done now by binning every photo. Google has to make a decision to move forward with their camera and use it to its fullest potential in which they are not doing now.

Still a 12mp image. The file size is larger however and there's more info from the sensor to play with.
RAW images will also not be compressed in a lossy way
Maybe some gcam ports will allow us to take photos in 50 mpx...
I invite you to my post here:
https://forum.xda-developers.com/t/samsung-isocell-gn1-sensor.4359031/#post-85911883
Its a quad Bayer subpixel layout. Because it groups four of the same color pixel together it only has 12.5 mp of color data. The 50 mp claim is marketing bs. Essentially it just upscales the 12.5 mp image using the extra luma data. The sensor is also too small for 50 mp to turn out well.
The main advantage is you can do an HDR photo with one exposure. Because there's four subpixels, you can have four different exposure values with one photo. Although I don't think Google is utilizing this.
A 50mp picture would be a total waste with the lenses in these phones. The "extra" detail that a 50mp could show would be offset by the poor quality lenses (I'm speaking in general terms here - not specifically about one phone or another). These tiny phone lenses can only produce so much sharpness, clarity and detail. In other words, eventually it's the lenses that are the limiting factor in the picture quality and putting in a sensor with such high resolution that it greatly exceeds the quality of the lens will not produce better images.
By binning the sensor pixels, you get the benefit of "larger pixels" (so more light absorption) without exceeding the quality limitations of the lenses.

Question Samsung ISOCELL GN1 Sensor?

If the Google Pixel 6 Uses Samsung's ISOCELL GN1 Sensor then these sources should be true as well for the Pixel 6 hardware
"Dual Pixel technology creates 100-million phase-detecting photodiodes for snappy auto-focusing and light information that can be translated up to 100 megapixels
...
To address various imaging preferences of the users, some smartphone makers put more emphasis on extremely detailed images with ultra-high resolutions, while some choose bigger pixels for bright results in low-light environments. The new Samsung ISOCELL GN1 fulfills these multiple needs at once with Dual Pixel and Tetracell technologies.
...
When capturing images, a single pixel output is created by merging the outputs from the two photodiodes within the pixel. Samsung also provides a software algorithm that takes light information from each photodiode to produce image resolutions comparable to 100Mp.
...
By binning four pixel signals into one, Tetracell doubles the image sensor’s pixel size to 2.4μm and quadruples the light sensitivity to take brighter 12.5Mp photographs.
...
For premium video quality, the image sensor supports video recording at up to 8K resolution at 30 frames-per-second (fps)."

So can someone please tell me how to enable all this on my Pixel 6. Or who to pay to put this feature in a gcam mod...
or port the samsung camera apk...
Or how to formalize my request to google to unlock this already hardware present feature.....
+++++++++++++++ And if its the Samsung GN2 +++++++++++++++
"Packed with 50 million large, 1.4μm-sized pixels, the ISOCELL GN2 captures more light to give you brighter, clearer photos. With ISOCELL technology that isolated each pixel for lifelike color and remosaic technology for maximizing details, ISOCELL GN2 can push the resolution output to up to 100MP.
...
Capture everyday moments in incredible detail with the ISOCELL GN2’s 8K video support. When shooting in Full HD, the image sensor records at a whopping 480fps, producing truly cinematic and immersive slow-motion videos."

OR:
"For those who appreciate more detail in photographs or are prone to post-processing such as image cropping, the GN2 offers an option to take pictures in 100Mp resolutions. In 100Mp mode, the GN2 meticulously re-arranges the color pixels using an intelligent re-mosaic algorithm, creating three individual layers of 50Mp frames in green, red and blue. These frames are then up-scaled and merged to produce a single ultra-high 100Mp resolution photograph.
...
The GN2 supports full-HD videos at 480 frames-per-second (fps) or 4K at 120fps, enabling wider possibilities for mobile video-shooting."

It defenitly isnt the GN2
