In the field of CMOS sensors for mobile phones, Sony IMX and Samsung ISOCELL series are the most well-known, and are also standard for the vast majority of mid-to-high-end mobile phones. In addition, Howey Technology (OV) is also an important player, its OV50A, OV48C (48 million pixels, 1/1.32 inch), OVB0B (200 million pixels, 1/1.28 inch) performance is not bad, and the brand belongs to the domestic semiconductor manufacturer Vail shares, and now it is also a domestic CMOS brother.
In addition to Howey Technology, the domestic CMOS field actually has a good strength of the supplier, it is SmartSens ,the brand recently released a model of SC550XS 50 million pixel CMOS, the comprehensive quality is comparable to Sony IMX766, is expected to start sending samples in Q2 2022, is expected to achieve mass production in Q3 2022.
The STAVI SC550XS features a 22nm HKMG Stack process, which consumes 43% less power than the 40nm process commonly used by the industry's previous generation of main camera CIS, providing better battery life for high-end smartphones.
The Stavoy SC550XS has a resolution of 50 megapixels, a pixel size of 1.0μm, supports 2x2 SmartQCell microlens technology, and qE (quantum efficiency) of up to 82%, resulting in excellent low-light scene shooting performance. AllPix ADAF technology enables 100% full pixel focus and is equipped with a MIPI C-PHY 3.0Gsps high-speed data transmission interface.
The Stawell SC550XS also features SmartClarity imaging technology, as well as patented SFCPixel and PixGain HDR technologies, which meet the needs of flagship smartphone main cameras in full-color night vision imaging, high dynamic range, and low-power performance.
Among them, PixGain HDR technology is a combination of High Gain (high conversion gain) and Low Gain (low conversion gain) under the same frame exposure, which can achieve high-quality HDR imaging without ghosting during sports shooting. The sensor supports triple exposure row overlapping HDR up to 4K 30fps up to 120dB and dual exposure row overlapping HDR mode at 60fps 100dB.
In general, the specifications of the STEP SC550XS are similar to those of Sony IMX766, and the Samsung GN5 and Howey OV50A are at the sub-flagship level of 50 million pixel sensors. In theory, its offer should be lower than other competitors, and I don't know if it can help thousand-dollar mobile phones popularize the sub-flagship level 50 million pixel lens.
what? Who is the flagship 50MP sensor? The answer is naturally the four brothers of Samsung GN1, Sony IMX700, Sony IMX707 and Samsung GN2, whose sensor size is larger, and the GN2 even reaches 1/1.12 inch.
