So recently, the phone can be said to be the most powerful in the world at the moment Xiaomi Mi 11 has been officially sold. Some devices have arrived in Vietnam via portable line and are becoming very hot.
We will put aside the performance and temperature issues that are causing the network community of this Snapdargon 888 chip, which is also very likely because it has not been optimized by phone manufacturers. best way.
But in this article, I will mention the issue of image processing capabilities, or simply what this chip can do with the camera.
In addition to clusters such as GPUs, data communication clusters, etc., there is a processing cluster that is very interested in the ISP (Image Signal Processor: Image signal processor).
This is the processing cluster that is responsible for the recording and image processing capabilities of the phone camera. In short, the video or image looks good or not, and if it has many features or not, there is interference from this processing phrase.
According to what Qualcomm claims, with the Snapdragon 888 ISP in the chip will have 35% more powerful performance compared to last year’s generation.
So what will the new ISP bring to the phone camera in the near future?
Yes, the article was referenced from an Android Authority interview with the Vice President of Product Management for Camera at Qualcomm.
#first. Three cameras at the same time
With the launch of Spectra ISP, all Snapdragon SoCs are equipped with two ISPs. In a way, this makes it easier for smartphones to process 2 cameras at the same time and increase the image processing bandwidth for the camera.
This year, however, with the Snapdragon 888, Qualcomm added an image signal processor. Therefore, now inside the Snapdragon 888 chip there are up to 3 image signal processing clusters.
It also means that the phone can support recording from 3 cameras at the same time. The most recognizable application is that the user can change between 3 focal lengths from 3 cameras equipped on the phone.
But Qualcomm only provides technology, and how to operate and optimize it is up to the phone manufacturers. So maybe in the beginning, we still don’t have access to this cool feature.
#2. Super fast recording and playback
The race to scan frequency is very popular, current phones have a range of scan frequencies from 90Hz to 144Hz spanning many segments. However, the current videos do not reach that frame rate.
But with the Spectra 580 ISP of Snapdragon 888 is different, with 3 ISP clusters that help bandwidth up to 2.7 Gpix / s, we can record and play 4K 120fps video.
However, as I said, Qualcomm only provides technology, and how it will be deployed depends on the smartphone manufacturer as well as the developers of the software that supports 4K 120fps video playback.
# 3. Better HDR video
It can be seen, although the phone’s camera has been able to capture HDR increasingly better, but the ability to record video is not really so. Currently only the latest generation iPhone has been announced with complete Dolby HDR recording capabilities.
With the Snapdragon 888, Qualcomm adopts a technology called staggered HDR. Simply put, this is an innovation from photography technology, video will be shot with many different exposures in each frame with different shutter speeds.
This helps the sensor capture light and dark details as best as possible, just as the imaging technology is so popular today on smartphones.
However, in my opinion, this technology is quite difficult to succeed, because when shooting depends on the frame rate.
Moreover, unlike stills, for video, the light will not be fixed but constantly changed, so maybe in the near future we may not have a true HDR video on Android devices.
# 4. Smarter autofocus
Nearly all current smartphones are unable to autofocus at close range or in complicated conditions with complex subjects and lighting. But with Snapdragon 888, we hope Qualcomm will improve this problem.
Qualcomm has applied AI with a huge library of libraries so that AI can know what image they are taking. What’s more, Qualcomm also uses real people for this technology.
Qualcomm developed eye-tracking technology to distinguish a target subject on a certain scene, and then applied the obtained data to the Snapdragon 888’s AI to best detect the subject.
Qualcomm hopes that in the future, with the addition of new data, this capability will be increasingly improved on the next generations.
The addition of an ISP to the Snapdragon chip has taken the phone’s shooting and recording capabilities to another leap.
But this is just a hardware technology, for complete development, it is necessary for phone manufacturers as well as software to go together.
And we all hope the day when the phone camera can get close to a popular camera will not be far away.
Above is the article about what the Snapdragon 888 chip brings to the camera image processing in the future.
