Projection system using multiple color gamuts for image display
The patent US12075021B2 describes a projection system designed to enhance image display capabilities using six predefined primary colors. This system incorporates at least one spatial modulator and an electronic processor that processes two-dimensional video data to generate two sets of intensity values corresponding to two distinct color gamuts. The first color gamut is derived from a combination of the predefined primaries, while the second color gamut is defined by the remaining energy output after accounting for the first. The processor employs a method that includes subtracting a luminance threshold from the video data to create a third set of intensity values, which are then adjusted to form the second color gamut. The first color gamut is generated by subtracting the second from the original video data, followed by further processing to produce the final intensity values.
Additionally, the patent outlines a method for rendering wide color gamut images, emphasizing the importance of blending the output gamut with the native color gamut of the projection system. This blending process is designed to maintain the hue of the original video data while ensuring that the distinct sets of predefined primaries are utilized effectively. The claims also specify that the first and second sets of primaries consist of different wavelengths of red, green, and blue, enhancing the system's ability to produce a broader range of colors. The patent further includes provisions for a non-transitory computer-readable medium that stores instructions for executing these processes, ensuring that the projection system can efficiently manage and display high-quality images.
