COLOR CORRECTION SYSTEM AND METHOD FOR ACCURATE COLOR REPRODUCTION FROM A COMPOSITE COLOR IMAGE SENSOR

摘要

The various embodiments of the present invention disclose a system and method for estimating one or more correction coefficients, and performing color correction based on a correction coefficients associated with a composite Red Green Blue -Infrared (RGB-IR) sensor, wherein the method for performing color correction based on correction coefficients associated with a composite Red Green Blue -Infrared (RGB-IR) sensor comprises calculating a luminance signal using RGB luminance values, checking if the RGB luminance value is more than a predefined threshold value, checking if the RGB luminance value is equal to saturation value if the luminance is bright upon identifying that RGB luminance value is greater than a predefined threshold value using median filter, checking whether the visible pixel values are saturated if the RGB luminance value of IR pixel value is saturated, and replacing the visible pixel value with an IR pixel value if the visible pixel value is saturated.
