COLUMN A/D CONVERTER, COLUMN A/D CONVERSION METHOD, SOLID-STATE IMAGING ELEMENT AND CAMERA SYSTEM

摘要

A solid-state imaging device having an analog-digital converter, and an analog-digital conversion method are described herein. An example of a solid-state imaging device includes a column processing section that includes a low-level bit latching section. The low-level bit latching section receives a comparator output from a comparator and a count output from a counter, and the low-level bit latching section latches a count value.
