Solid-state imaging device, signal processing method, and electronic device

A signal processing method comprising:

• adding electric signals output from a plurality of pixel units sharing a shared VSL on the shared VSL of
• a solid-state imaging device including:
• a pixel array unit in which pixel units which output the electric signals obtained by photoelectric conversion are arranged at least in a horizontal direction;
• and
• the shared VSL being a vertical signal line (VSL) shared by the plurality of pixel units adjacent to each other in the horizontal direction.

An electronic device comprising:

• an optical system which condenses light;
• and
• a solid-state imaging device which receives light and takes an image, wherein the solid-state imaging device includes:
• a pixel array unit in which pixel units which output electric signals obtained by photoelectric conversion are arranged at least in a horizontal direction;
• and
• a shared VSL being a vertical signal line (VSL) shared by a plurality of pixel units adjacent to each other in the horizontal direction, and
• is configured such that the electric signals output from the plurality of pixel units which shares the shared VSL are added on the shared VSL.
