Image sensor circuits including shared floating diffusion regions
An image sensor can include a plurality of photoelectric conversion elements arranged in a matrix. A plurality of floating diffusion regions can be shared by respective corresponding pairs of adjacent photoelectric conversion elements. A plurality of charge-transmission transistors can respectively correspond to the photoelectric conversion elements, where each of the charge-transmission transistors are connected between a corresponding one of the plurality of photoelectric conversion elements and a corresponding one of the plurality of floating diffusion regions. A plurality of charge-transmission lines can be commonly connected to gates of respective corresponding pairs of adjacent rows of charge-transmission transistors, where each of the respective corresponding pairs of adjacent rows of charge-transmission transistors can be connected to respective ones of the plurality of photoelectric conversion elements in different adjacent rows of floating diffusion regions.
