When taking selfies, many friends will encounter the problem of dark selfie photos or excessive noise.，This problem is often caused by the insufficient light sensitivity of the front lens sensor of the smartphone。 To solve this problem，Major smartphone manufacturers have tried many solutions，Some of these solutions can indeed improve the selfie experience in dark light environments，However, it often has certain limitations。
face this problem，OPPO, which has been leading the development of smartphone selfie experience, has come up with the latest solution，It is the "Super Sensitive Cat Eye Lens" on OPPO Reno7 Pro! Next, I will take you to analyze this new technology, which can be called an artifact of dark-light selfies, from the perspectives of technology and real shooting.。

Get more light, the first IMX709 sensor
Front super-sensitive cat-eye lens of OPPO Reno7 Pro，Adopt the flagship sensor IMX709 deeply customized by OPPO and Sony。 The sensor adopts a new arrangement of RGBW primitives，And benefit from the world's leading 22nm process technology and DTI primitive isolation technology，The new RGBW sensor greatly improves the photosensitive performance while ensuring the image quality of the imaging。
Thanks to the design that introduces 2 W pixels in each group of 4 sub-pixels of the sensor，The W channel (white) light input of the IMX709 sensor is 60% higher than the G channel (green) light input of the traditional RGGB，resulting in a higher signal-to-noise ratio。 This makes the IMX709 have better photosensitive performance than other mobile phone front lens sensors，to achieve a more pure，and low noise image output。
Combining hardware and software, self-developed image processing unit
OPPO is also making efforts in the combination of software and hardware，The first in the industry to write algorithms into sensors，Let IMX709 integrate self-developed RGBW image fusion unit，Make it highly compatible with Epistar platform and third-party App and effectively reduce power consumption。
OPPO also equipped the front camera of OPPO Reno7 Pro with a moonlight night scene algorithm、Live HDR algorithm、Portrait Blur Algorithm、Advanced computational photography technology such as hardware-level DOL-HDR，It enables it to achieve excellent picture imaging in low-light environments, and it can also bring surprising portrait shooting experience in backlight environments，In particular, OPPO's portrait blur algorithm can achieve hair-level portrait matting through AI self-learning，And bring a layered background blur effect。
Analysis of Reno7 Pro selfie proofs is beautiful without fill light
Enhanced Light Sensitivity and Computational Photography，The front super-sensitive cat-eye lens of OPPO Reno7 Pro is backlit、Excellent portrait selfie effect in low light and other environments。 We specially invited a young lady to take a set of portrait selfie proofs containing various scenes，To illustrate that everyone understands the portrait selfie capability of OPPO Reno7 Pro。
It can be found，Even in backlit and dim light environments，OPPO Reno7 Pro's front super-sensitive cat-eye lens can still achieve clear and bright portrait photos，At the same time, there is no picture caused by overexposure of the face picture”pale”question。
also，It can also be seen from the portrait proofs of OPPO Reno7 Pro，The beautification algorithm carried by this model is very natural for the effect of portrait beautification，Smooth transition of picture details。 Can achieve skin whitening and smoothing at the same time，Ensure the three-dimensional effect of facial images，At the same time, the restoration of light and shadow levels is also very good.。
In addition to being able to take beautiful portrait photos，OPPO Reno7 Pro also has powerful video shooting capabilities。 With the help of the front ultra-sensitive cat-eye lens, no matter in backlight or dark light environment，Video screen shot by OPPO Reno7 Pro，Can make the subject of the portrait stand out，clear background details，Overall exposure is accurate，More balanced light and other excellent features，Greatly improves video quality。
Through the application of super-sensitive cat-eye lens，OPPO Reno7 Pro solves all kinds of front lens image imaging problems that everyone encounters in dark light selfies and other scenes to a certain extent，Allows the user to obtain an unrestricted optical condition，A freer portrait selfie experience。
Technological innovation has always been the main way to promote the upgrading of smartphone experience，The substantial improvement of OPPO Reno7 Pro's portrait selfie experience is naturally inseparable from OPPO's technological innovation in front camera imaging technology，OPPO is constantly using such technological innovations to create a smartphone experience that exceeds expectations for users.。
