AI Technical Summary
Technical Problem
Existing multi-projection systems face challenges in adjusting colors effectively across multiple projectors, leading to uneven brightness and an unnatural image output.
Method used
A color matching method and system that adjusts the colors of multiple projectors by determining the maximum luminance of each chromaticity, calculating relative luminance values, and transmitting set luminance values to each projector to maximize performance and reduce luminance variations.
Benefits of technology
The system enhances the sense of unity in images projected by multiple projectors by optimizing color output, leveraging the performance of each projector to achieve consistent brightness and color across the projected image.

Abstract
To adjust color while utilizing performance of a plurality of projectors in a multi-projection system.SOLUTION: A multi-projection for projecting one image by a plurality of projectors including a first projector and a second projector includes the steps of: acquiring maximum luminance of first chromaticity serving as a reference among a plurality of chromaticity and maximum luminance of second chromaticity different from the first chromaticity among the plurality of chromaticity in the first projector and the second projector; calculating a relative luminance value indicating a ratio of the maximum luminance of the second chromaticity to the maximum luminance of the first chromaticity in the first projector and the second projector; calculating a set luminance value for the second chromaticity of the first projector and the second projector based on the smallest value among the relative luminance value of the first projector and the relative luminance value of the second projector; and transmitting the set luminance value to each of the plurality of projectors.SELECTED DRAWING: Figure 2
