Abstract
A solid-state imaging device includes: a plurality of photoelectric conversion units arranged in rows and columns in a pixel region; a plurality of vertical transfer units arranged for corresponding columns of the photoelectric conversion units, and transfer, in a column direction, the signal charges read from the corresponding columns of the photoelectric conversion units; a first and a second horizontal transfer units arranged in parallel, and transfer, in a row direction, the signal charges transferred by the vertical transfer units; and a first and a second output units which (i) include floating diffusion units each formed in a region adjacent to an output end of a corresponding one of the first and the second horizontal transfer units and (ii) output, as electric signals, the transferred signal charges, wherein the floating diffusion units are disposed at greater intervals than adjacent ones of the horizontal transfer units.
