  • Patent number: 10021330
    Abstract: In a solid-state image capturing device, one or more vertical signal lines are disposed along one of columns of a pixel portion, and each of the vertical signal lines is divided into two parts between an upper region and a lower region of the pixel portion. Pixel signals output from a plurality of pixels of the one of the columns are read out to a plurality of column readout circuits through two or more parts of the vertical signal lines including the two parts of the one or more vertical signal lines disposed along the one of the columns. A division position of one vertical signal line among the vertical signal lines disposed in the pixel portion is different from a division position of another vertical signal line among the vertical signal lines in a row direction.
