TECNO has enhanced its Universal Tone technology by introducing an advanced multi-skin tone color chart, which currently includes 372 color swatches and continues to expand to encompass additional skin tones.
TECNO, a pioneering tech brand powered by artificial intelligence, is pushing the boundaries of multi-skin tone imaging through substantial enhancements to its Universal Tone technology.
The update includes an upgraded multi-skin tone colour card with 372 patches and enhancements to the Multi-Skin Tone Color Restoration Engine, significantly improving skin tone accuracy. These upgrades ensure more accurate and inclusive skin tone representation across diverse ethnicities and scenarios in mobile imaging.
This advancement will debut in the upcoming TECNO CAMON 40 Series, which will be unveiled at MWC Barcelona 2025 in March. Attendees at the annual trade show are invited to experience the benefits of this upgraded imaging technology firsthand at TECNO’s booth, located at Hall 6 Stand 6B11, Fira Gran Via.
Increasing the Diversity of Skin Tones in Databases for Realistic Portrayal
TECNO has notably expanded its Universal Tone multi-skin tone color chart to feature 372 color swatches, thereby building a more extensive and inclusive repository that encompasses a broad range of global skin tones, particularly catering to users from areas like Southeast Asia, South Asia, Africa, the Middle East, and Eastern Europe. The improved color palette does not just add more samples; it also refines the scientific and practical use of measuring and quantifying skin tones, acting as a vital reference point for calibrating Universal Tone algorithms. By offering a solid and varied collection of data points for these skin tone reconstruction algorithms, the updated Universal Tone can attain greater precision in depicting and presenting a broader array of complexions. At MWC 2025, TECNO plans to display two customized iterations of this refined color map: one emphasizing deeper skin shades and another concentrating on lighter ones, ensuring thorough representation throughout the vast continuum of human pigmentation.
Building on its progress, TECNO has taken a pioneering step by customizing a brand-new region-specific colour 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 milestone underscores 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 colour card, TECNO will continuously enhance 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.
Enhancing the Multi-Skin Tone Color Restoration Engine for Unmatched Precision and Accuracy
One of the key components of Universal Tone is the improved Multi-Skin Tone Color Restoration engine, which now features an advanced CCM Skin Tone Calibration Algorithm and a Spectrum-Based Automatic White Balance (AWB)Algorithm. This updated CCM algorithm utilizes TECNO’s enhanced Multi-skin Tone Color Card during training to ensure accurate color calibration. Meanwhile, the new AWB algorithm uses spectral predictions derived from skin tones to effectively tackle color shifting issues in single-color photographic scenes. It also enhances exposure and white balancing for different skin tones within the same image. These enhancements together result in more than a 50% increase in skin tone precision, providing naturally realistic portraits under varying skin tones and lighting situations.
In addition to these advancements, Universal Tone incorporates an Intelligent Skin-Tone Grading Exposure Algorithm. This feature allows for accurate adjustment of exposure levels across various skin tones, guaranteeing enhanced tonal balance and uniform brightness correction. These improvements collectively enhance Universal Tone’s ability to restore multiple skin tones effectively and provide outstanding performance under demanding circumstances like solid color backgrounds and backlit situations.
Driven by a firm dedication to minimizing skin tone bias and promoting inclusive image technologies, TECNO places these goals at the heart of their imaging advancements. They consistently enhance their Universal Tone technology and algorithms using a comprehensive skin tone dataset to guarantee precise and equitable depiction. Through this refined Universal Tone feature, TECNO maintains its position as a pioneer in mobile photography, equipped with one of the leading large-scale skin tone aesthetic analytics systems. Their ongoing quest for unparalleled technical prowess and inclusive creativity keeps pushing boundaries within the sector.
