Color management on Android has always been a thorny topic。Google added support for color management in Android 8.0 in 2017，At that time, wide color gamut (WCG) displays had already appeared in high-end smartphones.。In the next three years，Almost every new Android phone now supports color management，And most new device launches come with WCG displays。However，Support for color management in third-party vendor applications remains rudimentary。Google’s push to implement color management in third-party apps is less effective than Apple’s iOS，This means sRGB is still the standard color gamut on Android phones，Although applications can choose to use DCI-P3。in terms of hardware，One of the full color gamut applications used by Apple is to take 10bit WCG photos，It's more colorful (1.07 billion vs. 16.7 million)，And it was used as early as the iPhone 7 launched in 2016。
However，so far，No Android phone has yet mimicked Apple's lead，Because every Android smartphone lens will continue to capture 8bit images in sRGB。This will change next year，Because OPPO has announced that its next flagship phone OPPO Find X3 series will be launched in 2021，It will use a full path color management system，Support end-to-end 10bit color and WCG full path format photography。
In a May 2019 blog post，Google said，Wide color photos are coming to Android。 Google points out："Android is now at the point where the sRGB color gamut with 8 bits per color channel is not enough to take full advantage of display and camera technology。on Android，We've been working hard to make wide color photography end-to-end，For example, more bits and a larger color gamut。This means end users will be able to capture the richness of the scene，Share wide color pictures with friends and view wide color pictures on your phone。”
It’s been a year and a half since Google announced the news，OPPO has become the first company to announce end-to-end support for wide color photography。The reason why this is possible，It’s because like oppo findx2 pro、one plus8 pro、Android flagship phones like ASUS ROG phone 3 now have 10bit panels，Supports wider color gamut than sRGB。the reason why it is possible，It’s because of the 10bit and WCG photography support，The underlying operating system is ready。
The above mobile phones theoretically have the ability to display 10bit photos on the machine.，but until now，No device manufacturer has truly enabled end-to-end WCG photography capture capabilities yet。OPPO has now become the first device supplier to announce this news，Here's where Android phones can catch up to Apple's multi-year lead，For some display enthusiasts，This seems a bit late。
OPPO announced，ThatFull-path color management system will debut as part of its 2021 flagship phone OPPO Find X3 series。The company said，The system is the first Android color management system to support DCI-P3 wide color gamut and 10bit color depth，from capture、Both storage and display are supported。This will provide an "excellent viewing experience" with "true and accurate color reproduction"。
OPPO pointed out，Its new color management system has been developed，To support 10bit image capture and HEIF (High Efficiency Image Format)。OPPO admits the future lies in WCG and high color depth，to this end，Its R&D team improved the underlying system and hardware for color reproduction。The result is an end-to-end solution，Covers everything from image acquisition to calculation、coding、storage、decoding，All steps shown last，Supports HEIF images with 10bit high color depth and DCI-P3 wide color gamut。
Full-path color management system uses higher-specification algorithms and hardware to record color at capture time。OPPO’s R&D engineering in distortion correction、Computing has been popularized in areas such as multi-frame noise reduction (MFNR) and perceptual extreme super-resolution.。The company also noted，It will support image sensors with digital overlay (DOL) HDR mode。DOL-HDR technology combines different exposure conditions into one image，This means even taking photos in bright light，Also captures more vibrant colors。
OPPO then performs calibration，If not calibrated，Hardware will not reach its full potential。The company is already proud of its work on the Find X2 Pro display，This monitor has been recognized as a top-tier monitor。The findx3 series will be based on this。The company said，OPPO’s display calibration program achieves professional digital film-level color accuracy of approximately 0.4 JNCD (only noticeable color difference)，thus providing "consistently accurate screen display"。Its proprietary algorithm also ensures color gamut compatibility by adjusting DCI-P3 to the D65 white point (6504K) at the center of the color space。(It is worth noting that，Apple is the first to implement DCI-P3 on mobile devices with D65 white point and standard gamma of 2.2。）
Compared with standard 8bit color depth，10bit color depth reduces artificial visual characteristics caused by chromatic aberration。It can also further improve color gradients，to enhance the quality of visual content。
Apple started supporting HEIF in 2016，But Android phones continue to use the old JPEG format for photos。HEIF has better compression due to，In this way, similar quality can be maintained，At the same time, its size is approximately 50% of the JPEG image，This saves storage space。Find X3 series supports HEIF，OPPO notes that the format fully supports still images，EXIF，In-depth information and dynamic video。HEIF format can be further developed，to ensure compatibility with ultra-high color depth。(here，OPPO is presumably referring to future displays with wider Rec.2020 color gamut support。）
OPPO pointed out，It first attempts to display colors in the same pipeline on every screen to ensure accuracy and fidelity，to achieve unified standards，Now，It wants to do more to meet user needs。in 2018，Its R&D engineering team recognized the challenges faced by smartphone users with weak colors。Then，The team began systematic research on color correction，for a better visual experience。
Now，The company launches a comprehensive color correction solution。it says，It has conducted large-scale quantitative and qualitative research on color-blind users，Thus enabling it to upgrade the color correction solution to OPPO Color Correction Solution 2.0。The company is collaborating with Zhejiang University，Designed to accurately quantify color vision testing by sampling potential users，Find the best color correction solution。Presumably，Color correction systems of the future will be user-centric。Users can create their own unique, personalized display by selecting colors from the smartphone's color palette and testing and calibrating the system。
OPPO concludes，Its full-path color management system will be available first in its 2021 flagship Find X3 series。predictable，It will take quite a while for this technology to trickle down to lower price points。
