Image color correction method using scaling values and ccm
A recently granted patent (Publication Number: US11924590B2) discloses a method for color correction in images. The method involves receiving an image, determining scaling values based on the image, applying these values to the image to obtain a scaled image, applying a color correction matrix (CCM) to the scaled image, and then applying the scaling values again to obtain a color-corrected image. The CCM used in the process can be a polynomial CCM, and the second scaling value is the inverse of the first scaling value. Additionally, the method includes obtaining a correlated color temperature associated with the image and adjusting the CCM based on this temperature.
Furthermore, the patent describes a system that implements the color correction method. The system includes a processing circuit that receives the image, determines scaling values, applies the CCM, and generates the color-corrected image. The processing circuit can obtain the correlated color temperature through user input or by analyzing chromaticity coordinates associated with the image. It can also retrieve the appropriate CCM from a memory based on the correlated color temperature. Additionally, the system is capable of determining a spectral power distribution based on the color temperature and adjusting the CCM accordingly. Overall, this patented technology offers a comprehensive approach to color correction in images, ensuring accurate and consistent results for display or storage purposes.
