Abstract

Official abstract text for this publication.

In a solid-state imaging device which includes column analog-to-digital conversion circuits (ADCs) for converting pixel signals output from pixels into digital signals, each of the column ADCs includes a comparator which outputs a result of voltage comparison (comparison result signal) between the voltage of the pixel signal and an analog ramp voltage; a column counter which counts a column counter clock signal, which is either a clock signal or a phase-shifted clock signal, and stores a value represented by upper bits of a count value at a time of change in the comparison result signal; and a first latch unit which stores a value represented by lower bits of the count value. A second latch unit stores the value stored in the first latch unit.

First claim

Opening claim text (preview).

What is claimed is: 1. A solid-state imaging device which includes a plurality of sensing elements arranged in a matrix format for measuring physical quantities, and a plurality of column analog-to-digital conversion circuits (ADCs) for converting signals output from the sensing elements into digital signals, each of the column ADCs comprising: a comparator configured to output a comparison result signal which indicates a result of voltage comparison between a voltage of a signal…
