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

“Color inspires creativity and affects our perceptions of reality. That’s why we’ve enhanced every aspect of the color management system to add brilliant, high-quality visuals to more aspects of daily life.” said Bai, product manager at OPPO. “Based on the stellar color performance of the Find X2 Pro, the new Full-path Color 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 color experience, which unleashes content creators’ desire to explore, capture and express themselves fully.”

Considering the future trends lie in wide color gamut and high color depth, OPPO’s R&D engineering team did a decent job with color 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 color depth and the P3 wide color gamut. 

As a management system, the full-path color management system adopted higher specification algorithm 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. In the DOL-HDR technology, it synthesizes different exposure conditions into an image. Therefore, brilliant colors 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 color accuracy at around 0.4 JNCD, thereby delivering a consistently accurate display on the screen. On the other hands, OPPO’s proprietary algorithm guarantee color gamut compatibility by adjusting the DCI-P3 with the D65 white point at the center of the color space.

Compared with the depth of 8-bits, the 10-bit color depth tones down the artificial visual features brought about by gaps in colors. The 10-bit color depth further improves color 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 color depth.
