On November 26, Huawei's flagship mobile phone Mate70 series was officially announced. As expected by the market, the Mate70 series continues to make breakthroughs and innovations in imaging. Yu Chengdong, Executive Director of Huawei and Chairman of the Device BG, announced at the Huawei MATE ceremony that the Mate70 series is the industry's first red maple primary color camera, with more than 1.5 million spectral channels, which can capture ambient spectral information, empower different focal segments such as the main camera, ultra-wide angle, and telephoto macro, and promote the accuracy of color reproduction by 120%. This time, the Huawei Mate70 series introduces a multispectral camera into a mobile phone for the first time, which is another upgrade of Huawei in the field of camera color reproduction, and this move also brings the multispectral camera into the field of vision of consumers.

According to the official account of Geke Micro (688728.SH), a leading CIS manufacturer in China, multispectral imaging can not only perceive signals in a wider range from ultraviolet to near-infrared, but also improve the perception accuracy of the visible light band, inject richer spectral information into the image, and achieve more accurate color reproduction. In the current multispectral imaging scheme, the multispectral CIS camera has the advantage of being flexible and compact. Conventional sensors are equipped with RGB Bayer Color Filters, which usually only capture red, green, and blue colors. On the other hand, multispectral CIS is equipped with multi-channel filter materials on the surface of the image sensor to capture light of different wavelengths, and obtain richer and more accurate color information through back-end algorithm fusion calculation.

Yao Zhihai, the founder of Qiushi Spectrum, a domestic multispectral solution design manufacturer, also introduced in public information that spectroscopy technology has been widely used in the detection of physics, chemistry, medicine, agriculture and other fields, and also has important application value in industrial manufacturing fields such as food, automobiles, and semiconductors, such as: in the field of agriculture, spectroscopy technology can monitor the growth of plants, pests and diseases and the supply of nutrients through the analysis of the spectrum reflected by plants, and guide agricultural production; In the food industry, spectroscopy technology can also detect nutrients, contaminants and additives in food to ensure food hygiene and consumer health.

According to the official account of Geke Micro, relying on close collaboration and collaborative development with partners, the company has successfully mass-produced multispectral CIS, giving new capabilities to image sensors. According to public information, Qiushi Spectrum has also mass-produced imaging spectral chips in the visible light and near-infrared spectral bands based on silicon-based materials, and has been equipped with Qiushi Spectrum products in mobile phone models that have been released.

Huawei's flagship series of mobile phones, including the P series and the Mate series, have always been the vane of mobile phone mobile imaging. In 2018, Huawei released the P20 series and Mate 20 series mobile phones, driving the rapid application of telephoto and ultra-wide-angle lenses in Android brand mobile phones, and promoting mobile phones into the era of triple and even quad cameras. In 2019, Huawei P30 Pro was equipped with a periscope telephoto lens, bringing a new shooting experience, and once again promoting a new lens structure to become a trend, according to network statistics, in 2019, the global shipment of smartphones equipped with periscope telephoto lenses was about 15 million, and in 2020, it was about 83 million, ushering in a growth peak, with a growth rate of 400%.

The Mate 70 series brings spectral cameras to mobile phones, which is foreseeable to once again promote the development of mobile phone cameras, and may drive spectral cameras to become a new CIS function track after wide-angle, telephoto and other secondary cameras, bringing new vitality to the CIS industry. According to the research of GF Securities, at present, China has gradually entered the center of the stage in terms of multispectral scheme design, CIS and module & packaging and testing manufacturers, and the market size of mobile phone spectral imaging chips is expected to increase to 5~1 billion US dollars in the future, with a broad market space.
