Solid-state imaging device, signal processing method therefor, and electronic apparatus for enabling sensitivity correction

A signal processing method in a solid-state imaging device, wherein the solid-state imaging device includes a pixel unit in which a microlens is formed for a plurality of pixels in a manner such that a boundary of the microlens coincides with boundaries of the plurality of pixels, and a correction circuit of the solid-state imaging device corrects a sensitivity difference between pixels inside the pixel unit based on a correction coefficient, wherein the correction coefficient is provided per color temperature of light received by a pixel, and wherein the correction circuit uses a pixel signal of another pixel to estimate a color temperature of light received by the pixel, and performs correction based on the correction coefficient corresponding to the estimated color temperature.

An electronic apparatus provided with a solid-state imaging device that includes:

• a pixel unit in which a microlens is formed for a plurality of pixels in a manner such that a boundary of the microlens coincides with boundaries of the plurality of pixels;
• and
• a correction circuit configured to correct a sensitivity difference between pixels inside the pixel unit based on a correction coefficient, wherein the correction coefficient is provided per color temperature of light received by a pixel, and wherein the correction circuit uses a pixel signal of another pixel to estimate a color temperature of light received by the pixel, and performs correction based on the correction coefficient corresponding to the estimated color temperature.
