Signal processing device for solid-state imaging device, imaging apparatus having the signal processing device, signal processing method, and program which allow inter-pixel color mixing to be properly corrected even when color mixing ratios are two-dimensionally distributed in a pixel array surface

摘要

A signal processing device for a solid-state imaging device correcting inter-pixel color mixing in the solid-state imaging device in which color filters having a color component constituting a primary component among luminance components and other color components are disposed on a surface of a two-dimensional array of pixels including a photoelectric conversion element is disclosed. The signal processing device includes a parameter distribution unit two-dimensionally distributing correction parameters in a pixel array surface on which a plurality of pixels are arranged and a signal correcting unit correcting a signal for a pixel of interest using each of signals for a plurality of surrounding pixels adjacent to the pixel of interest in the pixel array surface and using two-dimensionally distributed correction parameters for each of the signals.
