“…We have recently investigated the color difference caused by spectral radiance wavelength change. The same amplitude loss ranging from 400 to 700 nm wavelengths will cause uneven color differences in human visual perception [14]. The CIE 1931 and CIE 1964 standard observer visual matching functions apply to the observation field range of 1 • -4 • and 10 • , respectively.…”

This paper proposes a simple spectral radiance backward characterization model based on the key wavelength strategy. The color difference of spectral wavelength radiance amplitude loss under different conditions, the spectral amplitude change of primary color, and the monotonicity of spectral amplitude were investigated. The key wavelengths were selected based on these three factors. We innovatively introduced the selected wavelengths into a backward characterization interpolation table, which was tested using different color samples. The experimental results indicate that the proposed model is more suitable for spectral backward characterization than the existing methods.

Reproducing colors under different ambient illumination conditions is a critical issue for monitors. This paper proposes a spectral-based color correction method for liquid crystal displays. The method establishes a model linking RGB values to display emission spectra and its inverse process. It estimates the white point of display images using emission and ambient light spectra. To solve the ill-posed nature of the display illuminance relationship, the method employs dimensionality reduction for spectra and dimensionality expansion for RGB drive values. Experimental results demonstrate that the proposed model achieves higher accuracy in spectral estimation compared to current methods. It effectively solves the color correction problem under ambient light. Validation images further indicate the effectiveness of the proposed method.
