OPPO announced today that the official release of the Full-path Colour Management System will premiere as part of its 2021 new flagship smartphones, Find X3 series. OPPO’s Full-path Colour Management System is the very first Android colour management system to support the full DCI-P3 wide gamut and 10-bit colour depth from capture, storage, and display. This delivers an outstanding viewing experience with its authentic and accurate colour reproduction.

“Colour inspires creativity and affects our perceptions of reality. That’s why we’ve enhanced every aspect of the colour management system to add brilliant, high-quality visuals to more aspects of daily life,” said Bai, product manager at OPPO. “Based on the stellar colour performance of the Find X2 Pro, the new Full-path Colour Management System has been meticulously developed to support for 10bit image capturing and HEIF format. We aim to deliver to our users a seamless and systematic colour experience, which unleashes content creators’ desire to explore, capture and express themselves fully.”

DCI-P3, 10-bit HEIF Images Supported from end-to-end — The Full-path Colour Management System Expands the Boundary of Visual Representation

Considering the future trends lie in wide colour gamut and high colour depth, OPPO’s R&D engineering team did a decent job with colour reproduction by improving the underlying system and hardware. The system is an end-to-end solution, covering all the steps from image acquisition, to computation, encoding, storage, decoding, and finally display, supporting a HEIF image with 10bit high colour depth and the P3 wide colour gamut.

As a management system, the full-path colour management system adopted higher specification algorithm and hardware to record colour when capturing. OPPO’s R&D engineering promoted algorithms in the areas such as distortion correction, multi-frame noise reduction and perceptual extreme super-resolution. Moreover, OPPO will support image sensors featuring Digital Overlap (DOL) HDR mode. In DOL-HDR technology, it synthesizes different exposure conditions into an image. Therefore, brilliant colours are captured even when pictures are taken against bright light.

Once we have the right hardware, calibration becomes the next important factor. OPPO’s screen calibration procedure enables a professional, digital film-grade colour accuracy at around 0.4 JNCD, thereby delivering a consistently accurate display on the screen. On the other hands, OPPO’s proprietary algorithm guarantee colour gamut compatibility by adjusting the DCI-P3 with the D65 white point at the centre of the colour space.

Compared with the depth of 8-bits, the 10-bit colour depth tones down the artificial visual features brought about by gaps in colours. The 10-bit colour depth further improves colour gradient to enhance the quality of visual content during creation and post-editing. Meanwhile, with a size only around 50% of a JPEG image, the new and powerful HEIF format fully supports a wide variety of multimedia, such as static images, Exif, depth information, and dynamic videos, thus giving users more creative freedom. It is also worth mentioning that the HEIF format can be further developed to ensure compatibility with respect to ultra-high colour depth.

Personalized Color Settings on Your Smartphone — Color Correction Solution for the Future of Imaging

At the recent OPPO INNO DAY 2020, OPPO Founder and CEO Tony Chen said that “we believe in ‘Technology for Mankind, Kindness for the World’. OPPO uses technology to empower people to capture the beauty around them and to unleash their imagination of the future; thereby helping everyone get the best out of life.

This manifests in OPPO’s R&D process in colour management. OPPO’s Full-path Color Management System is a fundamental function at the system level, and it is smart too. OPPO first sought to achieve a uniform standard with every screen showing colours in the same way to ensure accuracy and fidelity; now, we go deeper to seek to meet user needs with customization.

Back in 2018, OPPO’s R&D engineering team became aware of the challenges facing smartphone users with colour weakness. Considering about visual health, the team went on to initiate systematic research on the colour correction to address the needs of wider use for a better visual experience.

Next, OPPO will go one step further by introducing a comprehensive colour correction solution. By conducting a large-scale quantitative and qualitative study on those with colour weaknesses, we have upgraded the colour correction solution to OPPO Color Correction Solution 2.0.

Right now, OPPO is joining forces with Zhejiang University with an aim to find the optimal solution to colour correction by sampling potential users with accurate quantification of colour vision test. Dr Luo Ming, Professor of Color and Image Science at the university stated that “Nowadays, we are considering more about the individual difference for human well-being. In this case, the colour correction system of the future will be highly user-centric. Users can create their own unique and personalized display by choosing colours from the smartphone’s palette as well as testing and calibrating the system.”

For OPPO, years of innovation have led to new heights of colour expression for smartphone displays. The Full-path Color Management System will be first available in OPPO’s 2021 flagship Find X3 series.
