Enter 2022，A variety of new flagships equipped with Snapdragon 8 processors have been released，but we can see，These new machines do not continue the previous stacking design in terms of image configuration，Now that the competition for hardware equipment has stagnated，Where is the next direction of mobile photography? OPPO, the leading player in the field of mobile phone photography，Gives its own answer on the OPPO Find X5 series。
OPPO Find X5 Pro is equipped with OPPO's self-developed Mariana X chip and suspension anti-shake technology，At the same time, it is also the first flagship of OPPO’s famous video camera in Kazakhstan.。 So what kind of improvement can the use of these new technologies bring to the image performance of OPPO Find X5 Pro?，Can it continue the excellent image performance of the Find series? Let's take a look at the actual test。
Self-developed wafer、Suspension anti-shake、Hasselblad Image…… What is the use of these new technologies?
This time OPPO Find X5 Pro”a frame of image，use two wafers”As a product slogan，The chip naturally refers to the Snapdragon 8 processor and the self-developed Mariana MariSilicon X chip.。The powerful performance of Snapdragon 8 is believed to be known to everyone，I won't repeat it here。 Let's focus on the Mariana X, an OPPO self-developed imaging dedicated NPU.，What improvements can it provide to mobile photography? to understand this，We have to start with the process of taking pictures with a mobile phone。
Imagery from shot to final storage，It is a process of continuous data compression。 which involves three spaces：RAW-RGB-YUV，RAW is the raw data space，Here is the full lossless data provided by the CMOS sensor，But at this time the picture itself cannot be viewed directly，need to be in the RGB domain”to color”，Then output to the YUV domain for format conversion，Generate a picture in JPEG/HEIF format，Only then can we view photos normally。But it's worth noting that，The conversion process is not lossless，Every time the data is transformed，will suffer a certain loss。
In traditional mobile photography，Due to insufficient computing power of the processor ISP unit，When processing the image, you can only choose the image that has undergone two lossy conversions in the YUV domain.”incomplete”Information is processed，As a result, the image quality of the final film is relatively poor。Mariana X Epistar relies on its powerful computing power，Front processing from the traditional YUV domain to the RAW domain。Because of its powerful computing power，Up to 20bit wide RAW data processing can be supported，And it is based on more advanced AI algorithm and 20bitHDR fusion calculation，Do real-time calculations for each primitive，Can maximize the restoration of noise that should not appear，This means that the original image information in the RAW domain has a higher quality。
Just a static picture is far from enough to show the full strength of Mariana X Epistar。In current mobile photography，The processing pressure brought by night scene video makes it impossible to obtain the same good picture quality as taking pictures。 To solve this problem，The self-developed image processing unit MariLumi integrated by Mariana X Epistar is uniquely designed for the trend of video streaming，Can smoothly calculate the amount of video data for 4K specifications。The processing speed at the pixel level also allows the intelligent HDR fusion algorithm to run on the front end of this unit，Finally, the dynamic range of the picture has reached an astonishing 20bit 120db (20TOPS)，4 times better than Find X3 Pro，Reach 20bit Ultra HDR super dynamic range。
Thanks to the powerful computing power and energy efficiency ratio of Mariana MariSilicon X，For the first time, Android video has the ability to support 4K at the same time + 20bit RAW + AI + Extreme Specifications for Ultra HDR。 The end result is a video taken by the user，Every frame is a good photo。
While optimizing video quality,，The powerful video processing capability of Mariana X Epistar also brings a real improvement to some details in daily use。Third-party software such as WeChat，In order to realize the flexible switch between taking pictures and recording，When taking pictures, one frame of the video preview stream is usually intercepted，Thanks to the Mariana X chip that fronts the calculation process to the RAW domain，in wechat、Turn on the camera in apps such as Douyin and shoot directly，Also get the same high-quality picture as the system camera，No need to worry about image quality degradation。
Compared to taking pictures with a camera，The most convenient thing about the mobile phone is that it does not require the user to adjust various parameters at all.，Just press the shutter button and get a nice photo。And what plays an important role behind this is AWB (Automatic White Balance)、AE (Auto Exposure)、3A algorithm composed of AF (autofocus)。At present, the 3A algorithms of most manufacturers are purchased from wafer manufacturers，and sensor、The technical development of wafers and algorithms is out of sync。 Generally speaking，The development cycle of epistar basically needs more than two years，The sensor is updated and recalculated every year，Less time is required for algorithm development and training，This means that it is difficult for a manufacturer to be able to，Can combine software and hardware to achieve 100% effect。
Benefit from the vertical integration capabilities of Mariana X Epistar，OPPO conducts self-research and development of 3A algorithm on Find X5 Pro，Different problems in mobile phone images can be targeted to solve。For example, to improve white balance accuracy，Find X5 Pro uses a 13-channel spectral sensor，Cooperate with self-developed 3A algorithm，Can maximize the performance of 13-channel spectral sensor，Can restore the real environment light source information，Improve white balance effect，Natural colors in any light。Optical glass lens with the main camera，Can effectively reduce color cast，Achieve accurate color rendering。
Multi-scene real shooting experience OPPO Find X5 Pro performs well in taking pictures
After understanding the image configuration of Find X5 Pro，Let's use real shots to feel the image strength of Find X5 Pro。 From the proofs taken with the main camera of Find X5 Pro below, we can see that its imaging effect is very good，Can easily record the details of objects in the scene，When photographing buildings in natural light environments，Can well present the light and shadow effects brought by the lighting，At the same time, thanks to the support of Mariana X wafer and 13-channel spectral sensor，The white balance of the film is very accurate，Colors are more realistic and natural。
The telephoto lens has a high usage rate in actual shooting，Take advantage of the Find X5 Pro's telephoto lens，Users can easily take detailed and portrait photos of close objects。 As can be seen from the samples below，This lens not only has excellent imaging effect, but also，It can also help us effectively avoid the interference of the cluttered environment on the composition of the picture in daily shooting。
The ultra-wide-angle lens has a unique imaging effect when shooting large scenes，Has an irreplaceable position in daily shooting。The ultra-wide-angle lens of Find X5 Pro is shooting architecture、When taking group photos and other scenes, you can easily record a wider picture。In terms of image quality，The ultra-wide-angle lens of Find X5 Pro is not inferior to the main camera，I believe it can meet the picture quality needs of most users。
And in dark light environment，OPPO Find X5 Pro's optimization solution combining hardware and software does provide good imaging performance。 It can be seen from the sample below，in night mode，The finished film of OPPO Find X5 Pro has no obvious glare phenomenon。 Under the explanation of Mariana X chip and self-developed 3A algorithm，The noise problem that tends to occur in night scene shooting has been greatly improved，The photos are clean。on exposure，The suppression of the highlight part of the sample sheet is relatively good，Also retains sufficient shadow details，High screen latitude。
out of the picture，Major enhancements to the night scene video section for the Mariana X Epistar，We also tested。As you can see from the GIF，Compared with the iPhone, Find X5 Pro does not blindly improve the screen brightness，Exposure is more accurate。 Due to the powerful computing performance of the Mariana X wafer，The video screen of Find X5 Pro can also retain more details，better effect。 Another annoying ghosting problem on iPhone，It's also almost non-existent on the Find X5 Pro。
From the hardware configuration and real shooting experience, it can be seen that the image strength of OPPO Find X5 Pro has reached the top level among current flagship mobile phones，And super wide angle、wide angle、The telephoto three-camera combination can also meet the needs of users in many scenarios from landscape to portrait.。MariSilicon X wafers from Mariana、Application of new technologies such as suspension and anti-shake，You can also see OPPO's development and control of imaging technology。For those friends who have requirements for mobile phone image performance，OPPO Find X5 Pro is undoubtedly the best choice in the current mobile phone market。
