Abstract
A lens shading correction method includes providing lens shading correction profile data; calculating an intensity values of light passing through each of one or more visible light pass filters and each of one or more infrared light pass filters; calculating an average of the intensity values of the light passing through the one or more visible light pass filters; calculating an average of the intensity values of the light passing through the one or more infrared light pass filters; calculating a normalized intensity value of the light passing through the one or more infrared light pass filters, based on the calculated averages; adjusting one or more lens shading correction coefficients included in the lens shading correction profile data and each having a value varying depending on a frequency element of light, based on the calculated normalized intensity value; and correcting lens shading by using the adjusted lens shading correction coefficient.
