Recently, the famous digital blogger @ digital chat station on its own social platform broke the news: RGBW sensors are more and more, Sony as the front camera of the IMX709 has been commercialized, 50MP 1/1.4 " outsole main camera program is about to debut. Samsung will also take the lead in commercially using 64MP 1/1.7" sensors. From this news alone, we can see that in the next few months, there will be a new machine equipped with Sony's 50MP 1/1.4" outsole main camera program. If this is the case, then in terms of image strength, it will definitely bring us a better and better experience.
So why are more and more mobile phones equipped with RGBW sensors? In fact, compared with ordinary sensors, RGBW sensors have absolute advantages, not only can improve the sensitivity, but also, can avoid the problem of color casts. The earliest Huawei P8 used a 13-megapixel RGBW sensor, when Huawei officially announced that it could increase the brightness and contrast of photos by 32%, reduce color noise by 78% in low-light environments, and increase the amount of light ingested by 40% compared with traditional array sensors.
It is worth mentioning that this is still an RGBW sensor in 2015, the current OPPO Reno7 Pro, OPPO Find X5 Pro and other models have RGBW sensors, and is exclusive sony IMX709 sensor, according to relevant information: OPPO used RGBW pixel arrangement mode in IMX709, that is, in the traditional RGB arrangement to add white photosensitive unit. The advantage is that it can capture more light and improve the sensitivity in low light environments. Compared with the previous IMX615 used in the Reno6 series, it has 60% more light sensitivity and 35% less noise, which has a huge improvement in performance.
Of course, in addition to the extremely excellent sensor support, OPPO Find X5 Pro also has the blessing of the Mariana X chip, which can better play the full performance of the RGBW sensor, it is reported that the AI computing power of the OPPO Mariana X chip is 18Tops, compared with Apple's A15 chip AI computing power of 15.8Tops, and the energy efficiency of the OPPO Mariana X chip is 11.6Tops/w. From this set of data alone, it can be seen that the OPPO Mariana X chip is currently the world's top mobile NPU chip.
Moreover, in the process of use, the OPPO Mariana X chip AI capability has made a great leap forward, which can be directly processed and calculated in the RAW domain in the stage of image shooting, and can be computed up to 20bit RAW, which pushes the traditional calculation that can only be completed in post-processing to the forefront, and outputs high-quality data after lossless computation for the entire image link, which can bring improvement to subsequent image output and third-party APP calls.
In addition to the Mariana X chip, OPPO Find X5 Pro also added the blessing of 3A self-developed algorithm, which can improve the chromatic aberration problem caused by subject overexposure and underexposure during shooting, and finally achieve high-quality and color-accurate image rendering.
In short, with the blessing of various technologies, OPPO has played the performance of RGBW sensors to the extreme, which is the main reason why OPPO can always rank among the best in terms of image strength, and now it is rumored that the new RGBW sensor is about to be launched, then, it is likely to become another blade under OPPO. What do you think about that?
