Projector Color Calibration via Dynamic Gamut Adjustment

The system dynamically adjusts the gamut configuration based on the detected ambient light conditions. In ambient light, a first gamut is used that accounts for the presence of ambient illumination, while in darkroom conditions, a second gamut is applied that is optimized for darkness. This dynamic adaptation ensures color appearance consistency across different environments while maintaining reliable visual perception.

The calibration process transforms color values using different gamut parameters depending on the ambient light conditions. By changing the gamut parameters (from first gamut in ambient light to second gamut in darkroom), the system adapts the color output to maintain consistency across varying environmental conditions, resolving the contradiction between adaptability and perception stability.

The processor serves multiple functions: it detects ambient light conditions, determines the appropriate gamut configuration, transforms color values, and controls the projection device. By making the processor multi-functional, the system achieves color appearance consistency across different environments without proportionally increasing overall device complexity, as the processing unit already exists and is being utilized for additional calibration tasks.

The system introduces an intermediate calibration process that acts as a mediator between the input image and the projected output. This calibration process, which involves gamut transformation and color value adjustment, serves as an intermediary layer that adapts the content to different ambient light conditions, maintaining visual perception stability without requiring complex hardware changes.

The system dynamically switches between first and second gamut configurations based on ambient light detection. The processor determines whether the environment is ambient light or darkroom conditions and applies the appropriate gamut, enabling the projector to adapt to different environments while managing configuration complexity through automated detection and selection.

The system uses feedback from ambient light detection to automatically select the appropriate gamut configuration. The processor continuously monitors the ambient light conditions and adjusts the gamut setting accordingly, creating a closed-loop control system that adapts to environmental changes without requiring manual intervention, thus balancing environmental adaptation with manageable configuration complexity.
