OPPO Unveils Full-Path Color Management System
OPPO announced Wednesday the official release of its Full-Path Color Management System, which will premiere as part of its 2021 new flagship Find X3 series while also standing out as the first Android color management system to support the full DCI-P3 wide gamut and 10-bit color depth from capture, storage, and display.
“Based on the stellar color performance of the Find X2 Pro, the new Full-path Color Management System has been meticulously developed to support 10bit image capturing and HEIF format,” said Bai, product manager at OPPO.
Since the future trends lie in wide color gamut and high color depth, OPPO focused on color reproduction by improving the underlying system and hardware. As an end-to-end solution, the system covers all the steps from image acquisition, to computation, encoding, storage, decoding, and finally display, supporting a HEIF image with 10bit high color depth and the P3 wide color gamut.
As a management system, it also adopted higher specification algorithms and hardware to record color 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, which synthesizes different exposure conditions into an image to provide better color quality even under bright environment lighting.
The screen calibration procedure enables a professional, digital film-grade color accuracy at around 0.4 JNCD, thereby delivering a consistently accurate display on the screen. Meanwhile, the proprietary algorithm guarantees color gamut compatibility by adjusting the DCI-P3 with the D65 white point at the center of the color space.
The personalized color setting backed by the color correction solution will improve the imaging functions on the phone. Considering the visual health of users, OPPO’s team went on to initiate systematic research on color correction to address the needs of a wider user for a better visual experience ever since 2018. By conducting a large-scale quantitative and qualitative study on color weaknesses, OPPO upgraded its color correction solution to OPPO Color Correction Solution 2.0.

Currently, OPPO is joining hands with Zhejiang University, aiming to find the optimal solution for color correction by sampling potential users with accurate quantification of color vision test.
“Nowadays, we are focusing more on individual differences for people’s overall well-being. In this case, the color correction system of the future will be highly user-centric. Users can create their own unique and personalized display by choosing colors from the smartphone’s palette as well as testing and calibrating the system,” said Dr. Luo Ming, Professor of Color and Image Science at the university.
