TECNO upgrades its Universal Tone technology with a scientifically enhanced multi-skin tone colour card, now boasting 372 colour patches and continuously expanding to include more skin tone types.
TECNO, a cutting-edge, AI-driven technology company, is pushing the boundaries of multi-skin tone imaging technology with substantial advancements to its Universal Tone technology.
This update introduces an enhanced multi-skin tone color palette with 372 patches and improvements to the Multi-Skin Tone Color Restoration Engine, resulting in significantly improved skin tone accuracy. These enhancements guarantee more accurate and inclusive skin tone representation across various ethnicities and mobile imaging scenarios.
This innovation will be showcased at the TECNO CAMON 40 Series launch, which will take place at MWC Barcelona 2025 in March. Visitors to the annual trade show are welcomed to explore the advantages of this enhanced imaging technology at TECNO’s booth, situated at Hall 6 Stand 6B11, Fira Gran Via.
Enhancing the Skin Tone Library for Authentic Visual Representation
TECNO has substantially improved its Universal Tone multi-skin tone color chart to include 372 color patches to provide a more inclusive and comprehensive database representing a broad range of global skin tones, including those in Southeast Asia, South Asia, Africa, the Middle East, and Eastern Europe. This upgraded color chart not only increases the number of patches but also enhances the scientific and practical application of skin tone measurement and quantification, serving as a crucial calibration tool for Universal Tone algorithms. By providing a robust and diverse dataset for the skin tone restoration algorithms, the upgraded Universal Tone can achieve higher accuracy in capturing and representing a wider spectrum of skin tones. To demonstrate its innovation, TECNO will showcase two customized versions of this enhanced color chart at MWC 2025—one highlighting darker skin tones and the other focusing more on lighter skin tones, with comprehensive coverage across the diverse spectrum of skin tones.
Building on its progress, TECNO has taken a pioneering step by introducing a brand-new region-specific color card for Saudi Arabia, featuring 186 Saudi skin tone patches, in collaboration with the University of Leeds (UK) and Dar Al-Hekma University (Saudi Arabia) in late 2024. This achievement highlights TECNO's commitment to accurate and inclusive skin tone representation, ensuring precise and authentic reproduction of the diverse skin tones in the Saudi market. Starting with this regional color card, TECNO will continuously improve Universal Tone's capability for local tuning through in-depth research on skin tones, local scenarios, and lighting conditions, empowering algorithm optimization for regional specificity and delivering superior performance tailored to local consumer needs.
Improving the Multi-Skin Tone Color Restoration Engine for Unparalleled Precision and Reliability
As a key component of the Universal Tone system, the Multi-Skin Tone Color Restoration engine has been upgraded with a refined CCM Skin Tone Calibration Algorithm and Spectrum-Based Automatic White Balance (AWB) Algorithm. The CCM algorithm, trained using TECNO's upgraded Multi-skin Tone Color Card, provides precise color calibration, while the AWB algorithm, developed with spectral prediction based on skin tones, effectively addresses color shift challenges in monochromatic photo scenes and improves exposure and white balance for diverse skin tones within the same frame. Together, these advancements in the Multi-Skin Tone Color Restoration engine collectively result in an overall improvement of more than 50% in skin tone accuracy, ensuring natural, true-to-life portraits across various skin tones and lighting conditions.
In addition to these developments, Universal Tone incorporates an Intelligent Skin-Tone Grading Exposure Algorithm, which allows for precise adjustments to exposure across various skin tones, resulting in enhanced tone grading and consistent brightness recovery. Working together, these improvements greatly enhance Universal Tone's ability to restore multiple skin tones and provide superior performance in difficult situations such as backgrounds with pure colors and backlighting conditions.
Guided by a strong commitment to reducing skin tone bias and advancing inclusive imaging technology, TECNO has made these goals a top priority in its camera development strategy. TECNO regularly updates its Universal Tone technology and algorithms, using a large skin tone database to guarantee accurate and inclusive representation. With the improved Universal Tone, TECNO remains a leader in the mobile camera industry, boasting one of the most advanced skin tone aesthetic big data models. TECNO's ongoing pursuit of technological excellence and inclusive innovation continues to set new standards for the industry.
