COMBINED TONE AND GAMUT MAPPING FOR AUGMENTED REALITY DISPLAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240202892 titled 'COMBINED TONE AND GAMUT MAPPING FOR AUGMENTED REALITY DISPLAY
The abstract describes a computing system that adjusts colors in an image to be displayed on a screen by mapping input colors to output colors through a look-up table, adjusting lightness according to a tone curve, and mapping chroma to the output gamut of the display.
- The system receives an image with an input gamut and displays it on a screen with an output gamut.
- It uses a look-up table to map input colors to output colors by adjusting lightness and mapping chroma.
- The final colors for each pixel are determined based on the original color and the look-up table.
- The system displays the final colors on the screen to represent the original colors of the image.
Potential Applications: - Image processing and color correction in photography and graphic design. - Display technology for accurate color representation in monitors and TVs.
Problems Solved: - Ensures accurate color representation on displays with different gamuts. - Provides a systematic approach to adjusting colors in images for optimal display.
Benefits: - Improved color accuracy and consistency in image display. - Enhanced visual experience for users viewing images on different displays.
Commercial Applications: Title: Color Management System for Display Technology This technology can be used in: - Graphic design software for accurate color representation. - Monitor and TV manufacturing for better color calibration. - Photography editing tools for precise color correction.
Prior Art: Research color management systems and display technologies for similar approaches to color adjustment and mapping.
Frequently Updated Research: Stay updated on advancements in color management systems and display technologies for improved color accuracy and efficiency.
Questions about Color Management Systems: 1. How does this technology improve color accuracy on displays? 2. What are the key components of a color management system and how do they work together?
Original Abstract Submitted
in one embodiment, a computing system may receive an image to be displayed on a display. the image may be associated with an input gamut and the display may be associated with an output gamut. the system may access a look-up-table that maps input colors to output colors. the output color of corresponding to each input color may be determined by adjusting a lightness of the input color according to a pre-determined tone curve while keeping the hue and chroma constant and (2) mapping the chroma to the output gamut of the display. the system may determine a final color for each pixel of the pixels of the image based on the look-up-table and an original color of that pixel. the system may display the final colors of the pixels on the display to represent the original colors of the image.
