  • Publication number: 20170332026
    Abstract: The present disclosure relates to a solid-state image sensing apparatus, a control method, and an electronic device capable of reducing a settling time of a vertical signal line at the time of a read operation of pixels. A column processing unit A/D converts pixel signals of a plurality of pixels. A vertical signal line feeds the pixel signals output from the pixels to the A/D converter. A pull-up circuit increases a potential of the vertical signal line at the time of starting a read operation of the pixels. For example, the present disclosure can be applied to a CMOS (Complementary Metal-Oxide Semiconductor) image sensor that performs an interleaving operation or the like.

  • Patent number: 9451193
    Abstract: An electronic apparatus includes: a reference-signal output section that outputs a reference signal; a comparator that compares an electrical signal output from a pixel with the reference signal; a counter that obtains a count value as an AD conversion result of the electrical signal, the count value being obtained by counting time taken for the reference signal to change until the electrical signal and the reference signal match each other; and an auto-zero control section that performs control so that auto zero processing for setting the comparator is completed in a reset period, in which the pixel is reset, so that a comparison result indicating that two input signals supplied to the comparator match each other.
