Screen Color Calibration via Per-Channel Grayscale Adjustment

The patent changes the parameter adjustment approach from global luminance adjustment to per-channel grayscale value adjustment. By independently adjusting the grayscale values of red, green, and blue channels based on their respective emission energies and self-luminous energies, the system maintains color accuracy while adapting to external light conditions.

The patent applies different adjustment strategies to different color channels based on their specific characteristics. Each channel's grayscale values are adjusted independently according to its emission energy and self-luminous energy, allowing localized optimization of color representation rather than uniform global adjustment.

The patent incorporates feedback mechanisms by measuring the actual emission energies of each color channel and comparing them with the self-luminous energies. This feedback loop enables dynamic adjustment of grayscale values to maintain color accuracy while preventing over-adjustment that would cause distortion.

The system dynamically changes the grayscale values of each color channel based on real-time measurements of emission energy and self-luminous energy. This parameter adjustment prevents over-adjustment by grounding the luminance changes in actual physical measurements rather than assumptions.
