Xiaomi 12s Ultra secret revealed: a “dormant” ISP that will further improve photographic quality

About a month ago Xiaomi has unveiled its new 12S series smartphones, including the highly anticipated Xiaomi 12S Ultrathe result of collaboration with Leica and equipped with the largest photo sensor on the market today, a full 1 inch.

The new device, which brilliantly passed the bend test from JerryRigEverything, promises wonders in photographic fieldbut the various teardown they revealed several surprises just as far as capturing the image processing is concerned.

There first surprise comes from a user who took the phone apart and found a ISP chip (Image Signal Processor) not announced but appeared in a leak before the official launch. The chip Xiaomi C2 it would be dedicated exclusively to image processingbut Xiaomi would not have enabled it yet.

According to leaker Ice Universe the Chinese company would be doing i test of debug final and the would activate with a update OTA (Over The Air).

Following updatewe can expect a marked improvement in the speed of image management And photographic qualityas the dedicated ISP chips help in the processes of noise reduction, sharpnessAnd color optimization.

The other surprise comes from teardown from JerryRigEverything. The YouTuber, not happy with his endurance test, also disassembled Xiaomi 12S Ultra to verify the dimensions of the much vaunted 1 “sensor. As you can see from the video attached at the bottom of the article, in reality the sensor, albeit huge, it is not physically from a thumb.

At this point, however, one intervenes old convention within photographic. According to this rule, the sensor measurement it is not given by his own physical dimensions, but with the dimensions of a circle that can contain the aforementioned sensor. The story is quite curious, but it lies in the technology of first cameraswhich used cylindrical cathode ray tubes, and that measurement around the sensor was the only one that made sense to measure at time.

The convention has remained to this day and while for us it is there diagonal of the sensor it is not 1 inch, in the world of photography it’s a used measure makes perfect sense and Xiaomi has done nothing but use it.

Unfortunately in the others teardown the sensor real, so it’s hard to tell if Xiaomi is the only one to use this convention. Looking at the size of the 1 / 1.22 “Samsung ISOCELL HP1 200MP sensor it would seem so (image below), although it is difficult to define with certainty.

Zack also revealed the periscope, true engineering marvel, and other interesting ones curiosity, such as plastic lenses. We leave you to the video.
