Abstract
Provided is a solid-state image sensing device that performs an A/D conversion operation at high speed. A sample-and-hold sectionincluded in an A/D converter in a CMOS image sensor includes switches Sand Sand capacitor Cthat sample and hold a dark signal during each cycle period, switches Sand Sand capacitor Cthat sample and hold a bright signal during an odd-numbered cycle period, and switches Sand Sand capacitor Cthat sample and hold a bright signal during an even-numbered cycle period. While a bright signal is held with switch Splaced in a conducting state, the next bright signal can be sampled by placing switch Sin a conducting state.
