Device and method for compressing/decompressing lens shading compensation coefficient
A lens shading compensation coefficient compression device includes: a first differential block suitable for calculating a lens shading compensation coefficient between color channels and removing redundancy between the color channels; a second differential block suitable for calculating a lens shading compensation coefficient within color channels and removing redundancy within the color channels; and an entropy coding block suitable for performing entropy coding on remaining lens shading compensation coefficients and compressing the lens shading compensation coefficients.
