A New Era in Mobile Colour Accuracy
One of the other innovative technologies on display from TECNO at MWC 2025 is its revolutionary multispectral imaging sensor – the TECNO SpectraVision Camera, which is establishing an industry benchmark for colour reproduction in mobile photography.
This proprietary multispectral camera achieves a significant improvement in colour accuracy, enabling true-to-life image capture that mirrors human visual perception.
2MP SpectraVision Camera for True-to-Life Colour Accuracy
For years, achieving colour reproduction that closely matches visual perception of human eyes has remained a major challenge in mobile imaging technology. TECNO’s 2MP SpectraVision Camera is a real-time colour-rendering sensor designed to enhance colour accuracy significantly, delivering users with true-to-life colours. It employs an innovative 9-channel spectral sensor and self-developed spectral colour algorithm, which captures a broader spectrum of light and richer colour details, significantly surpassing traditional 4-channel RGGB and RYYB solutions, as well as single-point spectral sensors, thereby ensuring accurate colour reproduction in every section of an image.
By leveraging TECNO Imaging Matrix (TIM) technology, a new AI imaging “brain” that harmonises advanced hardware and AI-powered software, the SpectraVision Camera achieves unparalleled precision in colour restoration, aligning with the way the human eye perceives colours, even in complex lighting conditions such as stage lighting or urban night scenes, allowing your photos to truly reflect the moments you cherish.
Hardware and Software Synergy for Skin Tone Representation
The TECNO SpectraVision Camera excels in delivering accurate colour reproduction, even in challenging lighting conditions. Its advanced spectral clustering technology and full-spectrum environmental analysis enable fine-tuned colour restoration across different sections of an image.
Notably, the system’s prowess in portrait photography ensures natural skin tone rendering, overcoming the common pitfalls of colour distortion in multi-skin-tone scenarios. Integrated with TECNO Universal Tone (UT) algorithms – the most advanced AI-powered multi-skin tone imaging technology, which leverages TECNO’s industry-leading multi-skin tone colour card and inclusive skin tone database – the camera captures the nuances of diverse skin tones with remarkable accuracy. This seamless integration of advanced hardware and sophisticated software delivers a truly inclusive photographic experience, making it a game-changer for users seeking natural and authentic portraits in any lighting conditions.
MWC has long served as a key platform for the mobile technology industry, and TECNO has consistently leveraged this stage to showcase its groundbreaking imaging innovations. Guided by its brand ethos of “Stop at Nothing,” TECNO remains dedicated to delivering cutting-edge mobile imaging technologies, continuously advancing the field of imaging science. At MWC 2024, TECNO unveiled the PolarAce Imaging System and a multi-skin tone colour card, setting new standards for imaging accuracy.
The launch of the TECNO SpectraVision Camera reaffirms TECNO’s advanced technical capabilities and innovative leadership in mobile imaging. Looking ahead, TECNO remains committed to exploring new horizons in mobile imaging technology, delivering exceptional imaging products to consumers around the world.
