Infrared Image Modulation Coefficient Correction for Color Accuracy

The patent applies parameter changes by introducing modulation coefficients that dynamically adjust the luminance information from infrared images. These coefficients are calculated based on the ratio between infrared and visible light reflectance characteristics, allowing the system to transform infrared luminance data into values that accurately represent visible light appearance. This resolves the contradiction by modifying the parameter (luminance values) to match the target color space while preserving the infrared imaging capability.

The patent implements universality by designing the modulation coefficient correcting unit to perform multiple functions: it calculates reflectance ratios, determines appropriate modulation coefficients, and applies corrections to luminance information. This multi-functional approach improves color reproduction accuracy while minimizing the increase in device complexity by consolidating correction operations into a single versatile unit rather than adding separate specialized components.

The patent applies preliminary action by pre-calculating and storing modulation coefficients for different brightness levels and lighting conditions. When processing images, the system quickly retrieves the appropriate pre-computed coefficients based on the current brightness parameter rather than performing complex real-time calculations. This approach maintains high color accuracy across varying lighting conditions while significantly reducing the processing time required for each image.
