Abstract:
1. A method for converting, by an imaging device, an input colorspace associated with an image into an output colorspace associated with the image, wherein the imaging device is situated in an ambient lighting condition, the method comprising: receiving, by the imaging device, light data, wherein the light data includes information that pertains to the ambient light condition surrounding the imaging device; comparing a white point of a first colormap with the light data; based on comparing the white point of the first colormap with the light data, determining an adjustment factor; adjusting, based on the adjustment factor, a plurality of entries of the first colormap to generate a second colormap; and based on the second colormap, converting, by the imaging device, the input colorspace associated with the image into the output colorspace associated with the image, wherein comparing the white point of the first colormap with the light data comprises comparing the white point of the first colormap with an illuminant value of the light data to determine a difference between (i) the white point of the first colormap and (ii) the illuminant value of the light data, and wherein determining the adjustment factor further comprises based on the difference between (i) the white point of the first colormap and (ii) the illuminant value of the light data, determining the adjustment factor.
