Abstract
A solid state imaging device includes a pixel array unit in which color filters of a plurality of colors are arrayed with four pixels of vertical 2 pixels×horizontal 2 pixels as a same color unit that receives light of the same color, shared pixel transistors that are commonly used by a plurality of pixels are intensively arranged in one predetermined pixel in a unit of sharing, and a color of the color filter of a pixel where the shared pixel transistors are intensively arranged is a predetermined color among the plurality of colors. The present technology can be applied, for example, to a solid state imaging device such as a back-surface irradiation type CMOS image sensor.
