Samsung ISOCELL will release 100 million pixel CMOS: practical or gimmick?

Earlier, Xiaomi announced at the future image technology communication meeting on August 7 that Redmi had a new opportunity to use Samsung's 64-megapixel sensor. It also announced that it will also launch a 100-megapixel CMOS in the future, also from Samsung.

At present, the pixels of the CMOS sensor of the smartphone are constantly rising, not only Xiaomi, but Realme will also hold a communication meeting on August 15th, the protagonist is also a 64-megapixel camera sensor.

In fact, for the new sensor, Samsung ISOCELL officially announced that there will be "big news" on August 12, and it is widely expected that it will officially release a new 100 million-pixel CMOS sensor. In this way, Samsung has been "disclosure" in advance by Xiaomi. feel.



On August 12th, this big news, outside speculation is that Samsung will launch a new 108MP sensor on August 12, while rumors that this sensor will be available in 2020.

However, according to sources, if there is no accident, Xiaomi MIX4 should launch this 100 million pixel CMOS, and release it in the second half. In fact, the current technical information about this 100 million pixel sensor is very small. In the past, the battle of playing 10 million pixels seems to be a struggle to upgrade to 100 million pixels in the future.

According to the collection micro-network, Samsung's 100 million-pixel CMOS will use the new Quad Bayer array, which has 108MP pixels. Normally, the image will be output at 27MP resolution, which is four times smaller, using a 4-pixel method.

It is not clear whether the user can achieve 108MP pixel image output through the camera professional mode. Even if it can, it will cause considerable pressure on the CPU module, such as CPU, GPU and ISP.

Even if it can output, the capability of the first-stage image processing module may take a long time to process, the user needs to wait for the imaging output time to be longer, and the user experience is not good; the second is a picture of a billion-level pixel, which is not required by the average user. Their demands are more of an improvement in image quality. If you just improve the resolution and do not work hard on image quality, this is just a gimmick. Third, it is not known about the size of this 100 million pixel CMOS sensor. In the limited space of the mobile phone, the sensor size is certain. It will be compressed. Such a large pixel is placed on a relatively small size sensor. How to solve the interference between pixels is also questionable, because it may reduce the quality of the photo.

Of course, we can't deny that the change of the pixel of the photo sensor is a trend. From our point of view, the increase of the pixel is more a basis for improving the image quality. After Samsung's Quad Bayer array has been tuned, users only need to shoot at 1/4 of the original resolution, and then the device will automatically merge 4 of the pixels into 1 pixel to achieve more detailed image details. It is also the ultimate goal of Samsung billion-level sensors - improving picture quality and enriching details.
