New method improves in-camera color mapping using 2D chromaticity

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for in-camera colorimetric mapping that moves beyond traditional one-dimensional correlated color temperature (CCT) interpolation. This new approach utilizes a two-dimensional chromaticity space, allowing for more accurate color reproduction under modern lighting conditions like LEDs, which often deviate from the Planckian locus. By replacing CCT interpolation with a lightweight multilayer perceptron (MLP) trained on 2D chromaticity features, the system reduces angular reproduction error by an average of 22% in LED-lit scenes while maintaining compatibility with older lighting standards and supporting real-time deployment. AI

IMPACT Enhances color accuracy in digital imaging by adapting to modern lighting conditions, potentially improving visual fidelity in AI-driven applications.

    Off the Planckian Locus: Using 2D Chromaticity to Improve In-Camera Color

    arXiv:2511.17133v4 Announce Type: replace Abstract: Traditional in-camera colorimetric mapping relies on correlated color temperature (CCT)-based interpolation between pre-calibrated transforms optimized for Planckian illuminants such as CIE A and D65. However, modern lighting te…
