The OPPO Find X3 series, the next flagship smartphone from the company, will be the first to feature Full-path Color management system. OPPO says that Full-path Color management system is the first Android colour management system to support the full DCI-P3 wide colour gamut and 10-bit colour depth.
On the Find X3 series, this new colour management system will be supported from capture, storage and display. By adopting Full-path Color management system, OPPO says it will be able to deliver an immersive viewing experience and accurate colour reproduction. “The system is an end-to-end solution, covering all the steps from image acquisition, to computation, encoding, storage, decoding, and finally display,” the company said in a statement.

The Find X3 series, when it debuts in 2021, will support a HEIF image with full 10-bit high colour depth and the P3 wide gamut. The Chinese smartphone maker says the future of mobile devices is in wide colour gamut and high colour depth and the company’s R&D Institute improved the hardware and software to support this new Full-path Color management system.
In order to support high colour depth and wide colour gamut, OPPO had to adopt a high specification algorithm and hardware to record colour at the time of capture. The company is improving algorithms in the areas such as distortion correction, multi-frame noise reduction and perpetual extreme super-resolution. OPPO will also support image sensors featuring Digital Overlap (DOL) HDR mode.
With DOL-HDR technology, OPPO says it will be able to synthesise different exposure conditions into an image. This could allow OPPO to capture better colours against bright light. The company is yet to finalize the hardware, but this technology will first appear in Find X3 series.
Apart from capture, OPPO is also working on the screen calibration process to display wide colour gamut. It says the current screen calibration procedure enables a professional, digital film-grade colour accuracy at around 0.4 JNCD. With its proprietary algorithm, OPPO says it will be able to adjust DCI-P3 with the D65 white point at the center of the colour space to guarantee colour gamut compatibility.

With the 10-bit colour depth, the biggest advantage will come in the form of elimination of artificial visual features brought by gaps in colours. The 10-bit colour depth also improves colour gradient, enhancing the quality of visual content during creation and post-editing. OPPO says the new 10-bit HEIF image will be only 50 percent of the size of a JPEG image.
Bai Lang, Product Manager at OPPO, said the biggest challenge is how to preserve and reproduce colour without any loss. Lang explains that OPPO’s Full-path colour management system covers the five technical stages of capture, encoding, storage, decoding and display.
With the new colour management system, OPPO is building a system that is cognizant of both range of colours as well as number of colours. Smartphone makers are trying to support 10-bit colour depth with capture of videos but OPPO seems to be building it right into its software.
This should allow for a smartphone experience that supports wider colour gamut and high colour depth at the time of capture as well as display. “Color plays a key role in seeing the world,” Lang said at OPPO INNO DAY 2020. It needs to be seen whether OPPO succeeds in implementing the new Full-path Color management system with the launch of Find X3 series next year.
