M43 format sensor is not suitable for mobile phones, Xiaomi Mi 14 Ultra still insists on 1-inch main camera

As mobile phone camera sensors continue to strengthen, the card camera market is facing the challenge of being gradually replaced by high-end mobile phones. The frequency of new product launches has dropped significantly in the field of card machines with 1-inch format and M43 format.

According to the editor’s understanding, there are recent reports that some mobile phone manufacturers are pre-researching M43 format solutions, which further intensifies the impact on the lightweight camera market. However, today’s report points out that the M43 frame sensor will not be used in mobile phones in the short term. The main reason is that the 1.33-inch size is still too large for mobile phones. “According to the current project approval information, the next-generation super-large main camera will still use a 1-inch sensor (expected to appear on Xiaomi Mi 14 Ultra), but the enhanced version (1-inch) and the next generation (expected to appear on Xiaomi 15 Ultra) are likely to have bigger breakthroughs. ”

It is worth noting that in July 2022, Xiaomi 12S Ultra released Sony's 1-inch IMX989 flagship sensor globally for the first time, and subsequently opened it to other manufacturers for use. It is expected that in the next few years, the high-end flagship imaging mobile phone market will still be dominated by 1-inch CMOS.

IMX989 is a CMOS sensor with an advanced process. The actual size is 1.02 inches, has 50 million pixels, and uses a 4:3 aspect ratio instead of the conventional 3:2 ratio. The sensor also uses a Quad-Bayer color array and Octa-PD phase detection focusing system to achieve faster readout speeds, better light input and resolution, and allow each sub-pixel to have focusing capabilities. In addition, this CMOS also supports pixel fusion technology. The pixel area after fusion can reach 3.2µm, which is more suitable for shooting scenes in dark light environments.

With the continuous upgrading of mobile phone image sensors, high-end mobile phones are competing fiercely with the card machine market. Even if some manufacturers are developing M43 format solutions, they are unlikely to be applied to mobile phones in the short term. In the future, the high-end flagship imaging mobile phone market is expected to still be dominated by 1-inch CMOS, and competition in this field will continue to develop.
