After the release of Xiaomi Mi 8, the device has received many praises from the outside world. At the choice of the notch, everyone thought that Mi 8 could be the best smartphone of Xiaomi to use even before it came out. The product has excellent performance and a very powerful camera, which makes users feel the charm of the top of the eighth anniversary range. The Mi 8 continues to carry on the strength of the company with low price and high distribution, making it the flagship phone with the cheapest Snapdragon 845.
Although the Mi 8 series has received great attention, its design with the notch it has also been criticized by many users and Mi Fans. We believe that this product is a bit stalled, between appreciation and disapproval. Today there is news that Xiaomi will launch a small series in the second half of the year, these new smartphones will most likely be named with the S, as a hypothetical Xiaomi Mi 8S. The main feature of this upcoming device is that it will be equipped with a fingerprint under the most mature screen or a best 3D facial recognition.
The Xiaomi Mi 8S will choose the last sensor IMX586 from Sony, which has an effective number of pixels, 48 millions, allowing four pixels in one, 0,8um for a single pixel, up to 1,6um for composite pixels and 90FPS video lenses recording at 4K resolution.
Sony, an image sensor manufacturer, has officially released the latest IMX586 smartphone image sensor with an effective pixel count of 48 million, over 40 million pixels for Huawei P20 Pro and 41 million pixels for Nokia Lumia 1020. SLR digital cameras are comparable, pixel sizes are as small as 0,8 μm and photosensitive components are just 1 / 2 inch (diagonal length 8,0 mm).
The report pointed out that Sony's CMOS image sensor for the first time reached the world's smallest pixel size of 0,8 μm. Sony said that in general, the smaller the pixel size, the lower the light collection efficiency per pixel unit, and a lower sensitivity will further reduce the saturation signal. However, the design and production technology ofIMX586 has greatly improved the light collection rate and photoelectric conversion rate and has the characteristics of high sensitivity and high saturation signal.
The sensor of the future!
According to Sony, the new image sensor uses a series of Quad Bayer color filters, while pixels Adjacent 2 × 2 they use the same color for high sensitivity shooting. When shooting in low light conditions, signals from four adjacent pixels are combined to increase sensitivity to a level equivalent to 1,6 micron of pixels (12 MP), obtaining bright and silent images. In the bright ambient like the outdoor daylight, the structure is transformed by its independent signal processing function and high-definition images with actual pixels up to 48 million can be output in real time.
This is similar to the way Huawei and Nokia phones have reached a very high resolution. The same applies to the 600 IMX sensor from 40 MP that Huawei and Sony have customized for the P20 Pro. At night, you can combine 4 pixels to produce a high-sensitivity, brighter and clearer 10MP photo.
To put it simply, in the future, a cell phone equipped with an IMX 586 sensor will have a camera from 48 MP complete during the day and a 12 MP camera with a super sampling reduction of 1,6 μm overnight. Because the small pixels of 0,8 μm hardly capture enough light to capture higher brightness photos, pixel synthesis essentially reaches larger pixels, capturing more light at the expense of resolution.
The words of Sony!
In turn, the IMX 586 make images with higher dynamic range and images in real time. Sony said: "The IMX586 sensor is equipped with Sony's unique exposure control and signal processing technology, resulting in dynamic gamma imaging and 4-time real-time imaging. Although the contrast between images is strong, it can prevent overexposure and exposure".
In addition, Sony's IMX586 image sensor is capable of shooting a variety of videos 4K / 90fps, 1080p / 240fps and 720p / 480fps, but does not support 1080P / 960fps ultra high frame rate slow motion video supported by Sony devices today. The new image sensor, Sony, should start supplying 2018 in September, at a cost of 3.000 yen, around 376 euro.
This means we may have to wait until 4 ° quarter of 2018 or at the beginning of 2019 to see a smartphone with the IMX586 sensor, but this may require the manufacturer to independently develop the ISP image signal processor, or wait for Qualcomm to release a chip with the new ISP, as currently the 845 SD ISP supports only sensors up to 32MP, so the Xiaomi smartphone of the 2019 should be equipped with one SD 855 that will support the camera from 48MP.
