TECNO has enhanced its Universal Tone technology through a scientifically improved 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.

This update features an enhanced multi-skin tone color chart comprising 372 swatches along with improvements to the Multi-Skin Tone Color Restoration Engine, dramatically boosting the precision of skin tones. These advancements guarantee greater accuracy and inclusivity in representing various skin tones for different ethnic backgrounds and situations within mobile photography.

This new feature will make its first appearance with the forthcoming TECNO CAMON 40 Series, set to launch during MWC Barcelona 2025 in March. Visitors attending the yearly exhibition can come to TECNO’s exhibit space, situated at Hall 6 Booth 6B11 within the Fira Gran Via venue, to personally try out the enhanced camera capabilities showcased here.

Increasing the Diversity of Skin Tones in Databases for Realistic Portrayal

TECNO has notably expanded its Universal Tone multispectrum color palette to feature 372 color swatches, thereby developing a more extensive and all-encompassing repository that encompasses a vast array of global skin tones spanning regions like Southeast Asia, South Asia, Africa, the Middle East, and Eastern Europe. The improved color chart not only adds additional shades but also refines both the scientific approach and practical use of measuring and categorizing 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 portraying an extended range of skin complexions. At MWC 2025, TECNO plans to present two customized iterations of this refined color map; one edition concentrating on deeper skin tones and another emphasizing lighter ones, ensuring thorough representation throughout the broad spectrum of human pigmentation.

Leveraging its advancements, TECNO has made a groundbreaking move by developing a new region-specific color chart exclusively for Saudi Arabia. This initiative includes 186 distinct shades representing various Saudi Arabian skin tones and was created in partnership with the University of Leeds (UK) and Dar Al-Hekma University (Saudi Arabia). Scheduled for release towards the end of 2024, this achievement highlights TECNO’s dedication to providing an accurate and comprehensive portrayal of skin tones within the Saudi marketplace. With this localized color palette as their foundation, TECNO plans to continually refine Universal Tone’s capabilities through extensive studies focused on skin tones, specific regional contexts, and varying light settings. These efforts aim at optimizing algorithms to cater specifically to these locales, thereby enhancing overall user experience according to individual preferences across different regions.

Improving the Multi-Skin Tone Color Restoration Engine for Enhanced 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 uses TECNO’s enhanced Multi-skin Tone Color Card during training to ensure accurate color calibration. Meanwhile, the AWB algorithm utilizes spectral predictions derived from skin tones to effectively tackle color shifts in single-color photography environments and enhance exposure and white balance for different skin tones within the same image. These enhancements together result in more than a 50% increase in skin tone precision, guaranteeing lifelike and naturally rendered portraits under varied skin complexions 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 scenes with solid color backgrounds or strong backlights.

Driven by a firm dedication to minimizing skin tone biases and promoting inclusive imaging solutions, TECNO places these goals at the heart of their imaging advancements. They continually enhance their Universal Tone technology and algorithms using an extensive skin tone dataset to guarantee precise and representative outcomes. Through this refined Universal Tone feature, TECNO remains a frontrunner in mobile photography, equipped with one of the most sophisticated large-scale skin tone analytics systems. Their ongoing quest for superior tech and equitable innovations keeps pushing boundaries within the sector.
