Smartway released a 50-megapixel 1/1.28-inch mobile phone image sensor SC580XS

According to news from this site on January 11, domestic CMOS manufacturer SmartSens today announced the launch of its first new 50-megapixel 1/1.28-inch image sensor - SC580XS.

This new product comes after SmartSite successfully mass-produced the first 50-megapixel 1/1.56-inch product SC550XS using the 22nm HKMG Stack process. , an upgraded product based on the same process platform. SC580XS is an image sensor with a 1.22µm pixel size. It adopts SmartSite's new generation pixel technology SFCPixel-2 as well as PixGain HDR, AllPix ADAF and many other technologies and processes. The introduction of these technologies and processes has brought higher pixel performance and wider dynamic range to SC580XS, making it an image sensor with better performance.

According to reports, SC580XS uses SmartSite PixGain HDR technology, which greatly improves the dynamic range and effectively suppresses motion artifacts through pixel high and low conversion gain synthesis under the same frame exposure. In addition, SC580XS also supports multiple high dynamic range modes such as triple exposure HDR and PixGain HDR VS, with a dynamic range of up to 120dB.

SC580XS uses SFCPixel-2 and PixGain technology, which reduces its read noise (RN) to only 0.7e-. Combined with related multi-sampling technology (CMS), its CMS 4x noise reduction can reach 40%. Compared with products with the same specifications in the industry, SC580XS has reduced read noise (RN) and fixed noise (FPN) by approximately 33% and 32% respectively, while PRNU has only slightly reduced by 4%.

In addition, SC580XS in four-in-one (summing) mode,

single pixel size reaches 2.44µm, which can bring 4K 120fps high frame rate video shooting function.

SC580XS is also equipped with SmartSix AllPix ADAF technology and Sparse PDAF technology to achieve better fast focusing effects in various lighting scenarios. In dark light scenes, the SC580XS turns on the AllPix ADAF mode and achieves 100% full-pixel focus through the combination of horizontal and vertical pixels, bringing faster and more accurate focusing effects to mobile phone cameras; in daily light scenes , SC580XS switches to Sparse PDAF mode, which accurately focuses through partial pixel phase detection, which can significantly save the power consumption of the image sensor.

Thanks to the newly upgraded read circuit architecture design and 22nm HKMG process, SC580XS has better low-power performance. SC580XS supports hardware Remosaic function and consumes as low as 500mW (25fps frame rate) in 50MP Full Size mode. At the same time, the power consumption of the SC580XS is as low as 190mW and 150mW for shooting 12.5MP images and 4K images respectively. Based on PixGain HDR high dynamic range mode, the power consumption of SC580XS when shooting 12.5MP images is 465mW (AllPix ADAF mode) and 310mW (Sparse PDAF mode), which helps to reduce and extend the power consumption of the smartphone. Maximum duration of continuous video recording.

This site learned from the official announcement of Smartway that SC580XS is currently accepting samples and is expected to be mass-produced in Q1 2024. .
