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;
• and
• a correction circuit of the solid-state imaging device configured to correct a sensitivity difference between pixels inside the pixel unit based on a correction coefficient,
• wherein the correction coefficient is calculated based on an added signal obtained by adding pixel signals of respective pixels of the pixel unit,
• wherein the correction coefficient is calculated based on a pixel average value obtained by dividing the added signal by a number of pixels of the pixel unit, and wherein the correction coefficient is calculated by a ratio between the pixel average value and a pixel signal of each pixel of the pixel unit.
