Сенсоры Sony и Samsung 48, 64 и 108мп Что объединяет и в чём разница.
Sony IMX was the staple image sensor for many mid-range handsets. But with changing times, the competition has bounced back.
Thus, mobile photophiles and spec-nerds out there were obviously looking forward to the successor. Samsung 64MP sensor is already powering a few phones in the market. On the other track, Redmi K30 is the first phone to side with Sony. Other notable attractions include dual selfie cameras, 27W fast charging support, and Snapdragon G octa-core chipset.
As for the front, you get a megapixel selfie snapper coupled with a 2MP depth unit. This is also the first phone to ship with Snapdragon chipset with dual-mode 5G support. Redmi has launched a 4G version also. Vivo X30 Pro flaunts a quad-camera panel with a megapixel primary sensor.
This is probably the Sony IMX sensor. This chipset has an integrated 5G modem and dedicated AI support on board. Other specs include a 6.

April 14, How to book your Covid test online in India April 7, February 5, March 16, April 17, The sensor features 48 effective megapixels and an ultra-compact pixel size of 0. Looking at the trend, more phones will launch with the sensor later this year. That said, it took almost seven years for smartphone companies to standardise megapixel and above resolution since the launch of Nokia PureView in At its time, Nokia PureView, a candybar feature phone, offered the largest ever sensor on a phone.
It offered 41 MP image sensor with high-performance Carl Zeiss optics. Things look really good for mobile photography enthusiasts. Samsung claims its latest sensor is capable of delivering brighter images in low-light conditions and more details in brighter settings. The sensor also comes with support for real-time HDR of up to decibles for more detailed colours.
According to Counterpoint Research, smartphone companies are going to launch megapixel camera phones. The research firm also predicted that the phones will be able to achieve megapixel camera resolution by end of the next year. Google does not even have dual cameras in its flagship Pixel phones and was relying on the stellar image quality through software.

Govt to allow sale of mobile phones online from April How to keep your Zoom meetings safe: MHA guidelines.Sony has introduced a new smartphone image sensor today and, looking at the IMX's impressive spec sheet, the new chip could help boost smartphone camera performance further in the next generation of high-end devices.
The sensor combines two key technologies: very high resolution and a 'Quad Bayer' color filter pattern to offer a series of clever processing modes. This allows it to squeeze 48MP onto its surface, but still requites a comparatively small pixel size of 0. The IMX is not just about pixel count, however. This allows it to offer several ways to process its data, depending on the conditions.
In low light image data from the four pixels in such an array is merged and processed as one single pixel, resulting in a reduced 12MP image resolution.
According to Sony, low light performance is comparable to large 1. In bright light the image signal processor can make full use of the sensor's 48MP pixel count, however, and capture high-resolution images or use the abundance of captured image data for high-quality digital zooming.
This requires processing to convert the 'Quad Bayer' data into an approximation of what a 48MP Bayer sensor would have captured. It'll be interesting to see how well this does.
Sony's write-up seems to allude to a third way of using the data. It talks about the sensor being able to display up to four times the dynamic range of conventional products. We suspect this uses the system Sony uses on its IMX chipwhere alternate pixels are switched off, mid exposure, protecting highlight capture while still recording full shadow detail. The Quad Bayer pattern would lend itself particularly well to this.
This three-mode approach to offering better performance in low light, higher DR in high contrast situations or high resolution when there's plenty of light may remind some readers of Fujifilm's Super CCD EXR technologywith which there are some obvious parallels.
As usual we don't know when the new sensor will see the light of day in a production smartphone, but the Sony Xperia XZ3 which is expected to be launched at IFA in September looks like a good candidate. Given Sony is the biggest sensor provider to the smartphone industry we should sooner or later see the IMX in non-Sony smartphones as well. If you have a closer look at the image, the 48Mpix image has higher resolution, ofcouse, high contrast, high luminosity low light more capable???
The high contrast and luminosity contradict the premise that the same info had been used for the two cases, 48Mpix quad Bayer process VS 12Mpix regular process without quad Bayer info.
This looks like a classic case or computational technique, if it really originate from a 48Mpix quad Bayer filter. I'm wondering if and when this sensor will be used for a new generation of compact cameras. Its dimension should allow the building of very long and bright lenses. At the same time, the computational techniques which are used in smartphone will help in having beautiful images, which could compete with bigger cameras.
I'm sure there will be always market for large sensor ILC, but being many efforts spent on smartphone technology, I believe it will be useful using them also for compact cameras.
Do you go to reviews sites for ovens and complain that no one is talking about the art of cooking? This is a gear review site, what exactly are you expecting? Can something be "very mediocre"? I thought the essence of "mediocre" was that it wasn't very anything. Who knows? Good point, I'm only slightly hesitating to call it below average because no other sensor on the market is currently a very good comparison.
Currently I'm inclined to think this quad bayer resolution boost is a mistake. I'd like less of usable pixels than more of useless pixels.
I'm wondering if it's worth it to buy a smartphone with this 48MP sensor. So I'd think the sensor has potential that hasn't be fully used.
Maybe that is wishful thinking.It is a CMOS image sensor for smartphones and has 48 megapixels, each of them only 0. The sensor was made available for smartphones back in September This sensor will take smartphone photography to next level.
Some of the smartphones have already started using it and here is the list of smartphones with 48MP Sony IMX sensor. It comes with a 6. The device also comes with Magic UI along with Android 9. The device also comes with mAh battery along with Super Charger. The device also comes with 25MP in-display selfie camera with a punch hole. Huawei Nova 4 was launched in December and again comes with the punch hole camera for selfies.
Are Sony, Huawei, and Samsung Going Too Far With 48MP Sensors for Phones?
There is also the 6. The front camera is a 25MP shooter and the top end variant of the device has a 48MP camera. This device is not yet available in the market although it was announced. It comes with 6. It should also be coming with the mAh battery. Redmi Note 7 Pro is expected to announce later this month.
There have been multiple leaks on this device and it is expected to come with 48MP rear camera and large capacity battery. We will update once the device is launched. Apart from this, there are new devices from Sony and Samsung expected to come with the IMX sensor. He can be contacted at nirmal nirmaltv. OnePlus has launched their new OnePlus 8 series smartphones globally today and there are two devicesThe only problem is that higher megapixel counts — which deliver sharper photos — often work against that goal, as the more megapixels you have, the smaller the pixels are on the image sensor.
Less space means less light captured by each pixel. Earlier this week, the company announced a megapixel image sensorcalled the IMX Now, the IMX is not the first image sensor to promise shots that are paradoxically sharper and brighter.
However, Huawei employed various tricks to mitigate the effect all those megapixels would typically have on darker shots. The sensors inside the P20 Pro are huge — easily many times larger than what you see in most smartphones. That makes the pixels themselves larger, which helps pull in that light you so badly need in less-than-ideal photo ops, but it causes a packaging nightmare in slimmer and more compact devices.
Sony IMX586 is the world’s highest-resolution smartphone camera sensor
Huawei also relied on the secondary monochrome sensor to capture luminosity, so the MP sensor could concentrate on sharpness.
The P20 Pro used pixel binning as well — a common tactic among high-megapixel smartphones — to combine four adjacent pixels into one. It too employs pixel binning when things get dark, downsampling the total 48 megapixels into 12 megapixels with increased light sensitivity. That said, the IMX is no larger than a conventional image sensor, which means it should be able to fit in more devices. But it is more versatile, and will likely appear in a greater breadth of flagship offerings because of its small footprint.

Any traditional photographer worth their salt can attest to the fact that more megapixels does not a better camera make, but when talking about smartphone photography the rules are a little bit different.
Related: Best camera phone. To achieve this impressive density, Sony has opted for smaller 0. This means that when the lights go down, the IMX can actually take the data from four pixels at a time and combine them into one, whilst also collating the available light and colour data to create a brighter, cleaner megapixel photo. Sony also promises four times the dynamic range compared to its previous top sensors, meaning the will deliver superior HDR high dynamic range photography compared to its predecessors.

I want to note that I'm not trying to push for or against certain smartphone manufacturers in this article. I'm not even attacking Sony for its work.
I'm sure the company's engineers have valid reasons every every choice made in the design of the sensor. I invite them, in case they are reading this article, to correct me or explain these choices.
Obviously comments and objections from you readers are also welcome, as long as you keep the conversation civil and respectful. In theory, yes, in practice, not so much.
Reading the specsheet published by Sonyyou can find the phrase "48 effective megapixels" everywhere. The table shows a resolution of x pixels which actually equals that number.
But let's take a closer look at the sensor In a sensor that uses a Bayer array pixel arrangement, each individual photoreceptor is physically filtered so that only green, red or blue light wavelengths can pass through a common practice that mimics the way the human eye operates. The sensor electronics are then responsible for transforming groups of adjacent pixels into the actual color that has been "perceived" by the individual pixel by borrowing information from neighbors and using some good old math.
This is done by taking the values of two green pixels G averaged, one red pixel R and one blue pixel B. On the IMX Sony uses a pixel arrangement called Quad Bayer arraywhich is nothing more than a classic Bayer Array arrangement used on virtually every existing smartphone sensor but where instead of every single pixel four pixels have been placed to form a 2x2 square.
Now, you can undestand how grouping 4 pixels of the same color next to each other in a Quad Bayer matrix is almost equivalent to having a sensor with a Bayer matrix with double-sized pixels measured on the side, quadruple as an area. However, we can't say that the information is wrong, because each individual photoreceptor is separate from the one adjacent to it, so technically there are 48 million Sony claims that this configuration allows both high sensitivity and high definition for its sensor.
I can't say anything about the sensitivity: by grouping 4 pixels of the same color together you get the equivalent of a single 1. What you have to remember, however, is that this is only slightly larger when compared to the more common Sony IMX which has pixels the size of 1. However, Sony says that it only uses the native resolution for high brightness because such small pixels really need a lot of light to perform properly.
The smaller the photoreceptor, the more likely it is that noise will appear resulting in degradation of image quality as the brightness drops. When the brightness is not the best, the pixel grouping system is used to reduce the noise and increase the overall sensitivity of the sensor best SNR value at the expense of the resolution.
