OPPO has begun preheating the next-generation flagship phone Find X7 series.WeiboThe product unveiled above will be the world’s first product to use the SONY LYT-900 one-inch photosensitive element, which uses a more advanced process and has better image quality, purity and dynamic range.
The complete specifications of the SONY LYT-900 sensor are still a mystery, but it has always been identified as the successor of the existing IMX 989 one-inch sensor. However, there were rumors in the past that the size of the LYT-900 was not one inch. Now Concerning the size, speculation has been broken by OPPO.
In terms of specifications, LYT-900 has the same 50 million pixels as IMX 989, but the process may be upgraded from 40 nm to 22 nm, which will significantly reduce power consumption and may have “Dual Conversion Gain”. , DCG) design.
DCG technology allows the photosensitive element to output both high-gain and low-gain signals at the same time. The former is sensitive to light but has many noise points, while the latter is less sensitive but has pure image quality. By combining the two, you can get a high tolerance High-definition and detailed photos, the dynamic range can reach 14.5 levels.
For comparison, the Light Hunter 900 sensor used by Xiaomi Mi 14 is said to have a higher tolerance than the IMX 989, and the dynamic range of the Light Hunter is 13.5 levels. In the camera field, the brightness difference is doubled to one level, which is equal to LYT-900 The brightness information that can be recorded is twice as high as that of Xiaomi Mi 14.
However, according to the past habits of Chinese mobile phone manufacturers, there is a high probability that OPPO Find X7 will have Pro, Ultra and other derivative models, and as usual, the entire series will not be equipped with LYT-900. There may only be the high-end Find X7 Pro or Find X7. Only the Ultra version will be used.
