US Patent 9001248 Solid state imaging device with additive read mode

A solid state imaging device includes a plurality of pixels, a plurality of vertical signal lines, a plurality of sample hold sections, a horizontal output section, and a horizontal scanning circuit. The horizontal output section is made up of a plurality of first horizontal signal lines connected to at least two or more vertical signal lines, and second horizontal signal lines connected to the plurality of first horizontal signal lines via the selection switches. The horizontal scanning circuit controls so that at least two of the plurality of selection switches are turned on and the pixel signal is output to the second horizontal signal lines when the pixel signal held in the sample hold sections is output to the horizontal signal lines.
