When smartphones first came out, they were positioned as "communication tools" for daily contact and communication. With the development of technology, smartphones have become more comprehensive in their functions, in addition to communication functions. , It also has many functions such as game consoles, music players, cameras, etc. Especially in recent years, the image level of the entire smart phone has been significantly improved, which is quite challenging for SLR cameras.
When it comes to the image level of smartphones, one cannot fail to mention the "anti-shake" thing. At present, mainstream smart phone brands generally carry two kinds of anti-shake technologies, namely optical anti-shake OIS and electronic anti-shake EIS. Among them, electronic image stabilization is a technology that mainly compensates for jitter by reducing image quality, and achieves a balance between image quality and image jitter; while optical image stabilization is avoided through the settings of optical components, such as lens settings or Reduce instrument jitter in the process of capturing optical signals, thereby improving imaging quality.
Compared with optical image stabilization, the cost of electronic image stabilization technology is much lower, so the image effect is much better than optical image stabilization, especially in night scene shooting On the one hand, the effect of optical image stabilization is definitely better than that of electronic image stabilization.
However, not all mobile phones are equipped with OIS because of its high cost, so it is usually used in high-end flagship mobile phones and a small number of sub-flagships; at the same time, OIS optical image stabilization has a micro motor and control The circuit will cause the lens module to require more space, which will further test the manufacturer's design ability to solve the problem of OIS lens module placement.This is also the reason why thousands of yuan phones and sub-flagships mainly use electronic image stabilization, while high-end flagships generally use optical image stabilization.
Of course, for consumers, the ability to use optical image stabilization in thousand-yuan phones and sub-flagships is definitely something to cheer about. According to the latest report from Thelec, a well-known Korean technology media, Samsung, as the global smartphone “big brother”, is applying optical image stabilization to lower-cost smartphones, namely the Samsung Galaxy A series. The current plan is Some models will be the first to follow up in 2021, and will be extended to all models in the series in 2022. Samsung hopes that through this technology, it can strengthen its competitiveness in the mid-range smartphone market.
In fact, Samsung’s move is also quite helpless, because domestic mobile phone brands such as Xiaomi and OV are becoming more competitive in market terminals, and shipments have unprecedented impact on Samsung, including Samsung's market share advantage in the global smartphone market including India, Southeast Asia, Europe and other markets is getting smaller and smaller.
Taking the latest data from the well-known data research organization Canalys as an example, in the second quarter of 2021, global smartphone shipments reached 316 million units, a 9% decrease from the previous quarter, although Samsung Leading with sales of 58 million units, but a year-on-year increase of only 8%. In contrast, the Chinese brand Xiaomi ranked second for the first time, with shipments of 52.8 million units, an increase of 83% year-on-year; OPPO and vivo each had 32.6 million units. And 31.2 million units ranked fourth and fifth, but the year-on-year growth was 26% and 27%, respectively.
Obviously,Samsung must make changes in order to maintain its status as a "mobile phone brother". In addition to canceling the Galaxy Note series before and taking the lead in the subdivision of folding screen mobile phones, this time it is the first to make the Samsung Galaxy A series models. The popularization of optical image stabilization is obviously one of the measures.
Of course, Samsung’s decision to make this major decision is also a good thing for the entire industry. Samsung’s mid-range products are equipped with OIS optical image stabilization, and those manufacturers that also carry EIS electronic image stabilization will obviously do. If you are in a hurry, you will inevitably follow up and stay competitive. It is expected to fully open a new era of smart phones with OIS optical image stabilization and decentralization!
