发明名称 Solid-state imaging apparatus for causing an FD capacitor value to be variable without increasing a number of elements
摘要 A solid-state imaging apparatus wherein an FD capacitor value is variable without increasing the number of elements. There is provided a solid-state imaging apparatus including a plurality of photoelectric conversion elements arranged in a horizontal direction and a vertical direction, for generating an electric charge by photoelectric conversion; a plurality of transfer transistors each connected to each of the photoelectric conversion elements, for transferring the electric charge generated by the plurality of photoelectric conversion elements; a plurality of floating diffusion regions for holding the electric charge transferred by the transfer transistors; a plurality of amplifiers each connected to each of the floating diffusion regions, for amplifying a signal based on the electric charge in the plurality of floating diffusion regions; and a connecting unit for connecting and disconnecting between the plurality of floating diffusion regions.

主权项 1. A solid-state imaging apparatus comprising: a plurality of rows of photoelectric conversion elements for generating electric charges; a plurality of transfer transistors each connected to each of the photoelectric conversion elements, for transferring the electric charges generated by the plurality of photoelectric conversion elements; a plurality of floating diffusion regions for holding electric charges transferred by the plurality of transfer transistors; a plurality of amplifying units each connected to each of the floating diffusion regions, for amplifying a signal based on an electric charge in the plurality of floating diffusion regions; a plurality of switches for connecting the plurality of floating diffusion regions to each other, each of the plurality of switches being arranged correspondingly to each pair of the rows of the photoelectric conversion elements; a scanning circuit for scanning each of said plurality of switches, the scanning circuit turning ON each of said plurality of switches by the scanning, in an order of arrangement of the switches, shifting successively from a one switch of a pair of rows of the photoelectric conversion elements to a next one switch of the next pair of rows of photoelectric conversion elements; and a Bayer array color filter.
