1125th，OPPO releasedOPPO Reno7series mobile phone。 As a sequel to the OPPO Reno series，Received the attention of many young ladies。 It is worth noting that，This time, the OPPO Reno7 series not only brought the industry's first aerospace-grade star rain lithography process and optical fiber thermal bending star ring breathing lamp design，It also has the blessing of ColorOS 12 and Dimensity 1200-MAX (OPPO Reno7 Pro)。 the most important is，This time OPPO Reno7 Pro also customized an IMX709 sensor for dark-light selfies with Sony。 Then, under the blessing of this front sensor with the strongest photosensitive ability in the world，How is the front-end performance of OPPO Reno7 Pro? Just take a pat with me。

Imaging capabilities are further advanced，more beautiful at night
can be seen，in the dim light，OPPO Reno7 Pro did not drop the chain because of the light。 The facial features of the young lady in the sample sheet are three-dimensional、clear，The complexion is also very fair。 The highlights of the background are not significantly overexposed，The details of the dark part have also been better restored。 At the same time in such a harsh environment，Noise can also be better controlled，indeed commendable。
certainly，In addition to the stacking on the hardware，Based on OPPO's years of exploration in the portrait field，Accumulated a wealth of algorithm experience。 On Reno7 Pro，OPPO even brought moonlight night scene algorithm、Live HDR algorithm、Portrait Blur Algorithm、Advanced computational photography technology such as hardware-level DOL-HDR。
Even in an environment where the outdoor light is not very sufficient，The front portrait of OPPO Reno7 Pro still has an excellent performance。 There is no obvious smearing effect in both the background blur effect and the details of the outline of the characters.，Miss sister's skin is also very delicate。
Here's another one with a more adequate outdoor lighting environment。 can be seen，Due to the influence of lighting environment，Miss sister's complexion looks fairer，But for the background lighting、lady's hair color、There is no color cast in clothing etc.。 At the same time, thanks to OPPO's accumulation in algorithms over the years，Between the blurred background and the young lady's hair，No traces of smearing，Every strand of hair is accurately represented。 The overall feeling is that the characters are more prominent，Quite a bit of SLR large-aperture bokeh。
In general，Whether it is night scene mode or portrait mode，OPPO Reno7 can handle it with ease。 According to OPPO description，Compared with the Reno6 series, the Reno7 series has a 60% increase in light sensitivity，Noise reduced by 35%。 So why does the Reno7 series have such a big improvement?
Let the algorithm "harden"，Write the algorithm to the sensor
This time on the OPPO Reno7 series (OPPO Reno7、OPPO Reno7 Pro），In addition to customizing a 22nm process technology IMX709 sensor，There is also a new RGBW pixel arrangement。
Actually，RGBW array sensors are not new，Back in 2015 on the OPPO R7 Plus released，Just use the RGBW sensor。 In a conventional RGGB Bayer array，Replace one of the G (green) primitives with a W (white) primitive without color information，Thereby improving the photosensitivity of OPPO R7 Plus。
However, many problems arose。 The first is due to the lack of a pixel，brought the problem of color cast。 And due to the limitations of sensor technology at that time，Limited computing power is difficult to support color guessing operations in complex environments。 Another point is limited to the maturity of pixel technology，False colors often appear in the finished film。 So OPPO gave up the RGBW pixel arrangement in subsequent products。
Although abandoned on the product，But OPPO has not given up on the research on RGBW。 finally，The R&D team combined the self-developed four-in-one primitive aggregation technology with the RGBW pixel arrangement，Developed a new arrangement of RGBW primitives。 That is to introduce 2 W primitives in each group of 4 sub-pictures，So that each primitive can have R、G、Discrimination ability of B and W signals。
The new arrangement method greatly improves the photosensitive ability at the same time，It also brings high-quality、Guarantee of high color accuracy。 It is worth noting that，In order to improve the efficiency of algorithm execution，It also directly writes OPPO's self-developed four-in-one graphics aggregation on the sensor、A series of algorithms such as RGBW color guessing。It is also the combination of software and hardware，It makes OPPO Reno7 Pro even without fill light at night，Can also take good-looking selfies。
OPPO Reno7 Pro as an iterative product of the OPPO Reno series，While maintaining an excellent portrait level，And brought us new surprises in self-developed black technology。 Behind the self-developed four-in-one primitive aggregation technology and RGBW pixel arrangement，We have also seen OPPO's continuous learning in the field of imaging、process of continuous improvement。 And it happens to be the self-developed technology that OPPO is constantly improving.，Drives the continuous upgrading of Reno series imaging technology and experience，towards Reno”Easily take the most beautiful portraits”The original intention of continue to move forward。
